The Difference Between Standard & Olympic Weight Plates

If you are considering purchasing weight plates, for either home or commercial use, it’s incredibly important to understand the differences between Olympic and Standard weightlifting equipment. If you only remember one thing from this article, make sure it is that Olympic weight plates have a 2" diameter hole, whereas standard weight plates only have a 1" diameter hole.

Only Olympic weight plates are compatible with Olympic weight lifting bars. Standard weight plates will not fit on an Olympic bar.

The Advantages of using Olympic Weight Plates

The main advantage of using Olympic weight plates over standard plates:

  1. Olympic weight plates are much more stable on the weight lifting bar.
  2. They are much more versatile - The number of exercises you can do with Olympic weight plates far outweighs standard weight plates.
  3. Olympic weight lifting bars are built to hold a greater total weight and some power racks and weight benches are made to fit the 7ft Olympic bars, as opposed to a 5ft or 6ft standard bar.

Different Types of Weight Plates

To summarise all the different kinds of weight plates you will find available to buy on the market we have provided an overview of each type: Studio, cast iron, rubber coated, technique, bumper and competition weight plates.

Studio Weight Plates

These are designed primarily for group exercise and exercise to music classes like Les Mills' BodyPump during which participants typically won’t be working with very heavy loads. These plates tend to be rubber coated, small in size, normally with handles and brightly coloured. They are easy to identify, are easy to store in the corner of your studio and can be quickly added and removed from specialised studio weight bars.


Rubber Weight Plates

Rubber weight plates are exactly the same as cast iron weight plates, but with an extra layer of rubber coating for safety, protection and longevity. The rubber coating helps both the weight plate and the floor to a certain degree, and will ensure that the plates are longer lasting and harder wearing.

One step up within this section is urethane coated plates. These are generally the same dimensions and shape as rubber plates, but are much more durable and less susceptible to markings and cosmetic damage. As well as marking less easily, these plates will not mark your floor, walls and other equipment like rubber plates will. They also have the benefit of not offgassing, which some rubber products do in gym environments creating an often unpleasant smell.

With rubber coated weight plates, it is quite common to see terms like “non-standard Olympic plates”. Non-standard Olympic plates are plates which are made to fit Olympic sized bars but have a reduced circumference when compared with a traditional Olympic weight plate. The main thing which makes a plate non-standard is the presence of grips, which are cut into the plate making them easier to lift off the ground, perform exercises without a bar and to place back in the weight rack.


Technique Bumper Weight Plates

Demand for bumper plates has been increasing over recent years due to growing popularity of Olympic lifting, some of which can be attributed to a rise in the number of people participating in CrossFit training.

A bumper plate is a solid rubber weight disc which can be safely used for performing Olympic lifts and can be dropped from a height during exercises like snatches and presses. The purpose of bumpers is to create a safe environment and allow certain exercises to be performed without the risk of damages to the floor, equipment or athlete.

Strength and conditioning coaches and gyms have long been using Olympic lifts in training, and weightlifting as a sport relies upon this core set of movements that require the use of bumper plates.

The first kind of bumper plate available is a technique plate. These are very basic and made from a simple single piece of rubber, without a metal ring around the hole. These only come in light weights and are perfect for introducing beginners to Olympic lifts and helping athletes improve their technique. Facilities tend only to have a small set of technique plates and they are normally only produced in 2.5kg and 5kg weights, otherwise training or competition plates would be used.


Training Bumper Weight Plates

Training bumper plates can vary slightly in depth but will all, for the most part, be a similar diameter. Top manufacturers like Eleiko and Zhangkong produce training plates which are the exact dimensions of competition weightlifting plates.

More affordable training bumper plates may not be the exact depth of IWF competition plates, however they will, for the most part, stand up the Olympic lifting requirements of a specialist facility, commercial gym or CrossFit box. Training plates usually come in black or are colour coded by weight.


Competition Bumper Plates

The factor which separates Olympic competition plates from training plates and all other kinds of free weights is the calibration. Official IWF Competition rules mean that plates need to be accurate to +0.1% and -0.05%. This means that production of a 25kg plate only has a 25 gram margin for error. The result is that Competition bumper plates are incredibly accurate and consistent, so the weight you are lifting is absolutely what you think it is. Origin Fitness is a proud distributor of Zhangkong Olympic weightlifting equipment which is IWF approved and has been selected to be used at the 2016 Rio Olympic games.
