On most of the Olympic weight plates in this ranking, the Item Weight field contradicts the set described in the title. One pair is sold as '2 x 10KG' — 20 kg of rubber — yet its data table reads 1.63 kg. A bumper set labelled '70KG SET (2 x 20KG + 2 x 10KG + 2 x 5KG)' lists 20 kg. A tri-grip set that advertises 50 kg, 70 kg and 100 kg options carries an Item Weight of 62 kg, which matches only the smallest 50 kg set plus the 12 kg 6FT bar — which means the headline kilo count is a marketing figure, not a shipping manifest.

We ranked ten of the best Olympic weight plates on Amazon on verified review volume, star rating, and whether each listing's own spec table agrees with the set it advertises. Price per kilo appears only where the listing supplies both numbers.

## The ranking

### 1. PhysKcal 50mm Tri-Grip Olympic Weight Plates, 1.25–25 kg

- Price: £33.99 | Amazon rating: 4.7 from 690 ratings
- Full review: https://www.ranked10.co.uk/fitness/best-weight-plates/physkcal-olympic-tri-grip-plates
- Buy on Amazon: https://www.amazon.co.uk/dp/B0B3QXZFG2?tag=ranked10-21

The top seller in Strength training Plates, with 690 ratings at 4.7 and the rare distinction of an Item Weight that actually adds up.

This is the highest-ranked set of Olympic weight plates here because of volume, not hype: 690 ratings at 4.7, and first place in Amazon's Strength training Plates category. It is also one of the few entries where the numbers agree. The colour option reads '5KG x 2' and the Item Weight reads 10 kg, which adds up exactly. By contrast, several pricier sets on this page fail that same test.

Each plate is solid cast iron with a 5 mm rubber coating, drilled with three cut-out grip holes and fitted with a 50 mm collar opening that takes standard Olympic barbell plates. The range runs from 1.25 kg to 25 kg, so a bar can be built up in small steps, and the thin profile lets you load more plates per side.

However, that 10 kg Item Weight only describes the 5 kg pair, and it is the figure to watch on any set of Olympic weight plates sold in multiple sizes. Two of the ratings are 1-star and two are 3-star — a small tail, but present. If you need calibrated competition tolerance, this listing does not state one.

Pros: 4.7 from 690 ratings — the largest review sample in this ranking; Number one best seller in Amazon's Strength training Plates category; Item Weight of 10 kg matches the '5KG x 2' colour option exactly; 5 mm rubber coating over solid cast iron, with a 50 mm collar opening; Sizes cover 1.25 kg to 25 kg in a thin profile that fits more per side
Cons: The 10 kg Item Weight only describes the 5 kg pair, not the heavier options; Two 1-star and two 3-star ratings sit in the histogram; No calibration tolerance is stated anywhere on the listing; Several pair sizes sit under one price entry, so check the selected option

### 2. PROIRON Olympic Bumper Plates, 2" Rubber, 5–25 kg, Single or Pair

- Price: £59.99 | Amazon rating: 4.7 from 246 ratings
- Full review: https://www.ranked10.co.uk/fitness/best-weight-plates/proiron-olympic-bumper-plates
- Buy on Amazon: https://www.amazon.co.uk/dp/B0BYJQC332?tag=ranked10-21

246 ratings at 4.7 and a stated IWF tolerance, held back by a spec table listing 1.63 kg against a '2 x 10KG' option.

These are the classic bumper plates: solid rubber, chrome-plated steel sleeves, a 50 mm centre hole, and a stated weight tolerance of -1.5% to +1.5% against IWF standards. At 4.7 from 246 ratings it earns its place. The catch is the Item Weight field, which reads 1.63 kg against a colour option reading 'b. 2 x 10KG'. A pair of 10 kg plates cannot weigh 1.63 kg, and neither can one of them.

The rubber is rated at 80-85 HRC hardness and described as low-elasticity, which is the property that stops a dropped plate bouncing back at you. Thick chrome sleeves should survive repeated loading, and the weight markings are embossed rather than printed.

That said, if you are buying for a competition setup and need a calibration certificate rather than a claim, these are not the Olympic weight plates for you. The listing states IWF compliance but supplies no sheet to back it up. Even so, for a home gym where plates get dropped on a concrete floor, the rubber construction is the point.

Pros: 4.7 from 246 ratings, ranked 14th in Strength training Plates; Stated weight tolerance of -1.5% to +1.5% to IWF standards; Solid rubber rated 80-85 HRC and described as low-elasticity for minimal bounce; Chrome-plated steel sleeves with a 50 mm centre hole
Cons: Item Weight field reads 1.63 kg against a '2 x 10KG' colour option; IWF compliance is stated but no calibration sheet is provided; One 1-star and one 2-star rating appear in the histogram; Sold as single or pair, so the £59.99 entry price depends on the option chosen

### 3. FK Sports Olympic Tri-Grip Weight Plates, Rubber-Coated Cast Iron

- Price: £46.99 | Amazon rating: 4.7 from 91 ratings
- Full review: https://www.ranked10.co.uk/fitness/best-weight-plates/fk-sports-olympic-weight-plates
- Buy on Amazon: https://www.amazon.co.uk/dp/B0CKTRPH4B?tag=ranked10-21

A 20 kg pair in the colour option against a 10 kg Item Weight and a count of one — three fields that do not agree.

Three fields on this listing point in different directions. The colour option reads 'C) 2 X 10KG', which implies 20 kg. The Item Weight reads 10 kg. The Number of Items reads 1, while the Unit Count reads 2.0 count. Which means the 10 kg almost certainly describes a single plate, and the pair is 20 kg.

In practice it is a straightforward formula for rubber coated weight plates: a cast iron core, a rubber shell, and a stainless steel inner ring. Three grip handles are cut into the face and a 2 inch opening fits Olympic bars, EZ curl bars and machines. Pairs run from 2.5 kg up to 25 kg.

Worth noting: 91 ratings is a small sample next to the 690 on the top-ranked pair, so the 4.7 here carries less weight. And if you want a listing that adds up on the first read, this is not it.

Pros: Cast iron core with a rubber coating and a stainless steel inner ring; 2 inch (50mm) opening fits Olympic bars, EZ curl bars and machines; Tri-grip handles allow use away from the bar; Pairs available from 2.5 kg to 25 kg; 4.7 rating from 91 reviews
Cons: Colour option says 2 x 10KG (20 kg) while Item Weight says 10 kg; Number of Items reads 1 while Unit Count reads 2.0 count; 91 ratings is a small sample next to the leaders in this list; No weight tolerance is stated

### 4. HOMCOM 2 x 2.5kg and 2 x 5kg Cast Iron Olympic Weight Plates

- Price: £31.99 | Amazon rating: 4.8 from 87 ratings
- Full review: https://www.ranked10.co.uk/fitness/best-weight-plates/homcom-olympic-tri-grip-plates
- Buy on Amazon: https://www.amazon.co.uk/dp/B09CM3PVD2?tag=ranked10-21

The highest rating here at 4.8, with a 15 kg Item Weight that matches the described set — but two spec fields belong to something else.

This is the best-rated set in this list at 4.8 from 87 ratings, and the arithmetic is honest. The bullets describe 2 x 2.5 kg plus 2 x 5 kg, totalling 15 kg, and the Item Weight field reads 15 kg. So far, so consistent. However, two other fields appear to belong to a different product entirely: Included Components reads 'Cover' and Item Type Name reads 'CAGE'. Neither describes Olympic weight plates.

The body here is steel with an enamel coating rather than cast iron, so it resists rust without the mass of cast iron weight plates. Three grip cut-outs let you use each disc on its own for twists or goblet squats. The centre hole is given as 5.4 cm against a 5 cm bar, and the dimensions are listed per plate: 19 cm x 2.5 cm at 2.5 kg, 23 cm x 3 cm at 5 kg.

The catch is the size ceiling. The largest plate in the described set is 5 kg, so it suits beginners and light accessory work rather than a serious squat or deadlift. Meanwhile, the product name mentions 10 kg plates that the bullet description does not include.

Pros: 4.8 from 87 ratings — the highest rating in this ranking; Item Weight of 15 kg matches the described 2 x 2.5 kg + 2 x 5 kg set; Enamel coating on a steel body resists mild rust and corrosion; Three grip cut-outs allow use without a barbell; Plate dimensions stated: 19 cm x 2.5 cm and 23 cm x 3 cm
Cons: Spec sheet lists Included Components as 'Cover' and Item Type Name as 'CAGE'; Heaviest plate in the described set is only 5 kg; Product name mentions 10 kg plates the bullets do not include; Steel with an enamel coating, not cast iron

### 5. Strongway Olympic Bumper Weight Plates, 70 kg Set, 2" / 50mm

- Price: £191.95 | Amazon rating: 4.5 from 78 ratings
- Full review: https://www.ranked10.co.uk/fitness/best-weight-plates/strongway-bumper-plates-70kg-set
- Buy on Amazon: https://www.amazon.co.uk/dp/B09RJRLMJT?tag=ranked10-21

Six plates and a 70 kg headline, with a 20 kg Item Weight describing one plate — and the largest 1-star tail in this list.

The colour option spells the set out: '70KG SET (2 X 20KG + 2 X 10KG + 2 X 5KG)'. The Number of Items reads 6, which matches six plates. Then the Item Weight reads 20 kg — the weight of a single 20 kg plate, not the set. Crucially, that is the number Amazon shows in comparison tables, and it makes this 70 kg set look like a 20 kg one.

Each plate is 45 cm in diameter with a 50 mm steel inner ring, coated in virgin rubber for floor protection and noise reduction. The diameter matters more than it sounds: it keeps the bar at a consistent height, which is what you want when pulling from the floor.

Even so, check the ratings before buying. Six of the 100 histogram units are 1-star and two are 2-star — a bigger complaint tail than either PhysKcal set carries. If you want bumper plates without that tail, the 4.7-rated crumb rubber pair further down is the fairer bet.

Pros: 70 kg set fully itemised: 2 x 20 kg, 2 x 10 kg and 2 x 5 kg; Number of Items reads 6, matching the six plates listed; 45 cm plate diameter keeps the bar at a consistent height; 50 mm steel inner ring with a virgin rubber coating
Cons: Item Weight reads 20 kg — one plate, not the set; Six 1-star and two 2-star ratings in the histogram; £191.95 buys plates only, with no bar included; The colour option is the only place the set contents are broken down

### 6. Lions Olympic Weight Plates, Rubber-Coated Cast Iron, 2" / 50mm

- Price: £23.95 | Amazon rating: 4.5 from 61 ratings
- Full review: https://www.ranked10.co.uk/fitness/best-weight-plates/lions-olympic-weight-plates
- Buy on Amazon: https://www.amazon.co.uk/dp/B0BD4MGCLH?tag=ranked10-21

The cheapest entry at £23.95, with a 15 kg Item Weight and a count of one — and no plate size stated anywhere.

At £23.95 this is the lowest price in the ranking. It is also the vaguest listing: the Item Weight reads 15 kg, the Number of Items reads 1, and nowhere in the bullets or the specs does it state which plate size that 15 kg refers to. A 15 kg plate is not a standard size, so the figure is hard to reconcile with anything you can load on a bar.

What is described is a solid cast iron core in a heavy-duty rubber shell with a 2 inch / 50mm bore, plus tri-grip handles for lifting the plate off the floor without a bar. The rubber is there to protect flooring and cut impact noise, and the grips are shaped for control when loading.

The 4.5 rating comes from 61 reviews, and seven of the 100 histogram units are 1-star — the joint-highest complaint share here. If you need to know precisely what arrives, these are not the Olympic weight plates to order blind.

Pros: Lowest price in this ranking at £23.95; Solid cast iron core inside a heavy-duty rubber shell; 2 inch / 50mm bore fits Olympic bars, dumbbells and EZ curl bars; Tri-grip handles allow lifting and carrying without a bar
Cons: Item Weight of 15 kg with no plate size stated anywhere on the listing; Seven 1-star ratings out of the histogram population; Number of Items reads 1, so it is a single plate; 4.5 from 61 ratings, below every set ranked above it

### 7. Strongway Tri-Grip Weight Plate Sets with 6FT or 7FT Barbell

- Price: £209.95 | Amazon rating: 4.8 from 56 ratings
- Full review: https://www.ranked10.co.uk/fitness/best-weight-plates/strongway-olympic-tri-grip-plates
- Buy on Amazon: https://www.amazon.co.uk/dp/B0BY9KSRHH?tag=ranked10-21

The only bundle here that includes a bar, and a 62 kg Item Weight that resolves exactly to the 50 kg set plus the 12 kg 6FT bar.

This is the joint-best rating in the list at 4.8 from 56 reviews, and the arithmetic resolves cleanly. The 50 kg set is 2 x 10 kg, 4 x 5 kg and 4 x 2.5 kg. Add the 12 kg 6FT bar and you get 62 kg — precisely the Item Weight on the listing. As a result, that figure describes the smallest configuration only, not the 70 kg or 100 kg option you may actually be buying.

The 7FT bar measures 220 cm and is rated to 700 lbs / 320 kg at 20 kg itself. The 6FT bar is 180 cm, rated to 550 lbs / 250 kg, and weighs 12 kg. Both have rotating sleeves, a 28 mm knurled centre and two quick-release collars. The plates are tri grip weight plates with virgin rubber over a steel inner ring.

At the same time, you are paying for a bar whether you need one or not. If you already own a 7FT bar, this bundle duplicates it. And because the plates are described only by set total, you cannot buy a single plate to fill a gap in the rack later.

Pros: 4.8 from 56 reviews, joint-highest rating in this ranking; 62 kg Item Weight resolves exactly to the 50 kg set plus the 12 kg 6FT bar; 7FT bar rated to 700 lbs / 320 kg; 6FT bar rated to 550 lbs / 250 kg; Two quick-release spring collars included with either bar; 100 kg set itemised as 2 x 20 kg, 2 x 15 kg, 2 x 10 kg and 2 x 5 kg
Cons: 62 kg Item Weight describes the smallest configuration only; No option to buy the plates without a bar; 2-star and 3-star ratings account for six histogram units; £209.95 is the highest price in this list

### 8. PhysKcal Crumb Rubber Bumper Plates, 50mm, 5–25 kg

- Price: £69.99 | Amazon rating: 4.7 from 48 ratings
- Full review: https://www.ranked10.co.uk/fitness/best-weight-plates/physkcal-rubber-plates-5-25kg
- Buy on Amazon: https://www.amazon.co.uk/dp/B0CZR4W2M5?tag=ranked10-21

A listing where the colour option and the Item Weight finally agree — 10KG x 2 against 20 kg — with a stated 60,000-drop test.

The colour option reads 'c) 10KG x 2' and the Item Weight reads 20 kg. Those two numbers agree, which is not a given on this page. The set carries 4.7 from 48 ratings and costs £69.99, or roughly £3.50 per kilo if you take the 10 kg pair.

These are made from recycled crumb rubber with a 50.5 mm stainless steel hub insert. That half-millimetre over the 50 mm standard is deliberate clearance, but it does mean a looser fit than a machined sleeve. The listing claims testing beyond 60,000 drops, and weight digits follow IWF colour coding for quick identification.

In theory, crumb rubber is the cheaper route into bumper plates; in practice, the grainy surface holds chalk and dust in a way smooth virgin rubber does not. And 48 ratings is a thin base. If you need a proven competition plate, this set of Olympic weight plates has not been on sale long enough to prove it.

Pros: Item Weight of 20 kg matches the '10KG x 2' colour option exactly; Recycled crumb rubber construction with a stainless steel hub insert; Stated testing beyond 60,000 drops; £69.99 for the 10 kg pair works out around £3.50 per kilo; IWF colour coding on the weight digits
Cons: 50.5 mm hub insert is a looser fit than a 50 mm machined sleeve; Grainy crumb rubber surface holds chalk and dust; Only 48 ratings to judge from; Two 1-star ratings appear in the histogram

### 9. GYM MASTER Fractional Change Plates, 2" Rubber, Full Set 15 kg

- Price: £89.99 | Amazon rating: 4.7 from 48 ratings
- Full review: https://www.ranked10.co.uk/fitness/best-weight-plates/gym-master-fractional-plates
- Buy on Amazon: https://www.amazon.co.uk/dp/B0BP2TJ2D3?tag=ranked10-21

Calibrated to +/- 10 g and honestly totalled at 15 kg, but at £89.99 it is £6 per kilo and the listing rules out commercial use.

This is the one listing here where the headline weight and the spec table agree without argument. The bullets say 'Full Set Total 15KG' and the Item Weight reads 15 kg. The set is pairs of 0.5, 1, 1.5, 2 and 2.5 kg plates — 7.5 kg per side. Calibration is stated as +/- 10 g, tighter than anything else on this page.

They are solid rubber with a 2 inch / 50mm bore, sized for micro loading when a 2.5 kg jump is too big a step. Dimensions are given per plate, from 13.5 cm across at 0.5 kg to 23 cm at 2.5 kg.

The catch is the price. £89.99 for 15 kg works out at £6 per kilo, roughly double the rate of the crumb rubber pair above. The listing also states plainly that the plates are not suitable for commercial use, so do not drop them. If you are not chasing small personal bests, skip this one.

Pros: 'Full Set Total 15KG' matches the 15 kg Item Weight exactly; Calibrated to +/- 10 g — the tightest tolerance stated on this page; Solid rubber with a 2 inch / 50mm bore; Covers 0.5 kg to 2.5 kg for micro loading; Per-plate dimensions given from 13.5 cm to 23 cm
Cons: £89.99 for 15 kg is £6 per kilo, about double the crumb rubber pair; Listing states it is not suitable for commercial use; Two 1-star ratings sit in the histogram; A set of this price that cannot be dropped

### 10. SPORTNOW Tri-Grip Weight Plate, 2" / 5cm, 20 kg Single

- Price: £17.99 | Amazon rating: 4.7 from 38 ratings
- Full review: https://www.ranked10.co.uk/fitness/best-weight-plates/sportnow-olympic-tri-grip-plate
- Buy on Amazon: https://www.amazon.co.uk/dp/B0FV3166CW?tag=ranked10-21

£17.99 for a single 20 kg plate, where the spec table says one item and the highlight text says a pair.

£17.99 for 20 kg is the lowest price per kilo in this ranking by a wide margin. It is also where the listing contradicts itself: the Item Highlight describes a 'Weight Disc Pair', while Number of Items, Number of Packs and Unit Count all read 1. On the evidence of the spec table, you are buying one plate.

The construction differs from everything above — a steel-filled core wrapped in PVC rather than cast iron or rubber, with three grip holes and a 5 cm centre hole. Diameter is 40 cm, against 45 cm on the Strongway bumpers, so the bar sits lower when these are the only plates loaded.

PVC is not bumper rubber. Drop this on a hard floor and the coating will not absorb the way a bumper plate does. Meanwhile, 38 ratings is the smallest sample here. If you want one cheap heavy plate for squats and rows, that is what it is. If you plan to drop it, it is not.

Pros: £17.99 for a 20 kg plate — the lowest price per kilo in this list; 4.7 rating from 38 reviews; Triple grip holes plus a 5 cm centre hole for 2 inch bars; PVC-coated steel core, no assembly required
Cons: Item Highlight says 'Weight Disc Pair' while Number of Items reads 1; 40 cm diameter against 45 cm on the Strongway bumpers; PVC coating, not rubber — not built for dropping; 38 ratings is the smallest sample in this ranking

## Verdict

For most homes, a 20 kg pair is the sensible buy: the PhysKcal tri-grip pair at £33.99 has 690 ratings and an Item Weight that matches its stated 5 kg x 2 option, while the PhysKcal crumb rubber pair at £69.99 reads 20 kg against a 2 x 10 kg option. If you need micro loading, the GYM MASTER fractional set is calibrated to +/- 10 g and totals a stated 15 kg — but at £89.99 that is £6 per kilo, and the listing rules out commercial use. If you want plates and a bar in one order, the Strongway tri-grip bundle is the only one here that ships with a bar; note that its 62 kg Item Weight describes the 50 kg set plus the 12 kg bar, not the 100 kg option. Either way, add up the individual plates before you check out. The headline figure on Olympic weight plates is advertising; the sum of the plate sizes is the specification.
