With the increased popularity of functional fitness and the weightlifting fan base growing, more health and fitness enthusiasts are getting into Olympic lifting.

If you’re looking to set up a home gym or add to your current collection, you might be wondering if Olympic bar dimensions differ from a standard barbell. The answer is yes, they do.

If you want to compete, you need to practice using Olympic-approved barbells and plates. Even if you don’t, you can’t beat the quality of an Olympic barbell.

Olympic lifting is tightly regulated, with both the barbells and weight plates conforming to specific standards set out by the main governing organization – International Weightlifting Federation.

In this guide, I’ll go through the different dimensions and specifications.

What are Olympic Barbell dimensions? Certified Olympic bar dimensions differ according to gender. Female bar weigh – 15 kg, measure – 2.01 m long, have a 25 mm shaft diameter, male bar, respectively, weigh – 20 kg, 2.2 m long, have a 28 mm shaft. Both bars have 2-inch loadable sleeves.

Olympic Barbell Dimensions and Weight

To use an Olympic barbell for competition, it has to be certified by the governing body responsible. Olympic barbells differ in weight and dimensions compared to standard barbells. They are typically stronger, heavier, and can handle much larger weight capacities. They also have thicker loadable sleeves and are made from a higher-quality material.

The history of Oly bar is related to the development of weightlifting as a celebrated and recognized sport. The transformation of the bar`s dimensions has been profoundly influenced by the standards of weightlifting competitions.

With the inception of the IWF (International Weightlifting Federation) in 1905, the need for uniformity and standardization became apparent. By the middle of the 20-th century, a classic Olympic bar was introduced, featuring a length of 220 cm and a weight of 20 kg for men and way later on, closer to 2000 the women’s version (slightly shorter and lighter) was introduced as well.

The design became more intricate over time, integrating revolving sleeves to enhance level of performance and reduce the risk of injury. The diameter of the barbell also evolved, providing a more comfortable and secure grip (25 mm for women and 28 mm for men).

In recent years, the emphasis on improving manufacturing processes and using better quality steel has resulted in highly standardized, refined tool. The modern Olympic barbell is a testament to thу constant evolution of weightlifting as a sport, reflecting the blending of tradition, innovation and scientific advancement.

Let’s look at the dimensions of an Olympic barbell in more detail:

1. Length

Length refers to the measurement taken from one side of the barbell end to the other end. It can be given in meters, centimeters, or millimeters. For male and female bar length is different: 220 cm and 201 cm respectively. When looking at how long is an Olympic barbell, you can split the measurements into shaft length and sleeve length. 

2. Shaft Length

Commercially available Olympic barbell grip shafts are 151 cm (51.6″) both for men and women. 

3. Sleeve Length

Sleeve length refers to the loadable plate length at either end of the barbell. This determines how many weight plates the Olympic bar can hold. This part of the bar is different: 35 cm for men and 25 cm for women.

4. Diameter

Diameter is the thickness of the barbell shaft and sleeves. This determines the grip comfort, difficulty level, and type of plates you can use with the bar. When considering how wide is an Olympic barbell, the diameter can be classified into shaft diameter and sleeve diameter.

5. Shaft Diameter

Generally, Olympic barbell diameter two ranges from 25 and 28 mm (0.98 and 1.1’’). This varies depending on the gender bar type. Men’s bar shafts are 28 mm thick. This is because it allows some flex, making it more suitable for dynamic lifting patterns such as the snatch and clean and jerk. Thicker 30-32 mm bars are usually better suited for powerlifting style squats, as the thicker bar is stiffer, meaning it’s less prone to moving around at the bottom of the squat.

The Olympic barbell width for women tends to be at the lower end at 25 mm to accommodate their smaller hand size compared to men. This allows them to use a hook grip without difficulty. Special Axel bars, also known as fat bars, are 2″ thick and mainly used in strongman competitions.

6. Sleeve Diameter

Sleeves need to be able to accommodate the 2″ hole size of Olympic-sized plates. Therefore, the sleeves are slightly smaller at 50 mm (just under 2″ thick). The thickness allows the loadable sleeves to spin whilst letting the Olympic plates slide on without too much restriction or falling off too easily. 

7. Weight 

Weight refers to how heavy the Olympic bar is. It’s different for men and women. Men’s Olympic bars weigh 20 kg (44 lbs) whilst women’s Olympic bars weigh 15 kg (33 lbs). There are specialty bars that weigh more, but these are rare and not usually used in competitive Olympic weightlifting

IWF Specifications

The International Weightlifting Federation (IWF) comprises 193 affiliated national federations from 5 continents. They are the controlling body for weightlifting, and are recognized by the International Olympic Committee (IOC) as the sole controlling organization. They mainly regulate Olympic weightlifting, consisting of the snatch and clean and jerk. Bars regulated by the IWF may be referred to as Olympic barbells, Oly bars, WL bars, or weightlifting bars.

According to the IWF technical rules book, these are the specifications a men’s Olympic barbell needs to be:

Full LengthShaft Grip LengthShaft DiameterSleeve DiameterWeight
220 cm / 86.6″151 cm / 51.6″28 mm / 1.1″50 mm / 1.97″20 kg / 44 lbs

The knurling pattern on men’s Olympic weightlifting bar follows a specific diagram given by the IWF, usually with no center knurling to stop the bar from rubbing against your neck during the lift.

Compared to men, women’s weightlifting bars have shorter sleeves and a smaller shaft diameter to cater to their smaller hand sizes. They also weigh less to cater to the physiological differences.

These are the IWF specifications for women’s Olympic barbells:

Full LengthShaft Grip LengthShaft DiameterSleeve DiameterWeight
201 cm / 79.1″151 cm / 51.6″25 mm / 0.98″50 mm / 1.97″33 lbs / 15 kg

Unofficial Olympic Barbells

Even if a bar is called an Olympic barbell, it doesn’t mean it complies with IWF standards. Most of the barbells advertised as Olympic don’t comply and will have slightly different measurements and features.

The unofficial Olympic bars can be put into three categories:

  1. The barbell complies with federation regulations, but isn’t certified.
  2. The barbell is very close to the regulations, but doesn’t quite comply.
  3. The barbell has 2 diameter sleeves for men and women, but is quite different from governing body specifications.

Throughout the three categories, If you find a bar that’s advertised as ‘Olympic’, you can expect 2″ diameter sleeves, but the other measurements will most likely vary. This means that the barbells will fit official Olympic plates, but can’t be used for competition.

If you’re looking to add an Olympic barbell to your home gym, having a certified barbell isn’t necessary. Unless you’re training for an officially sanctioned competition, using a bar very close to the specifications or one that compiles but isn’t certified is appropriate.

Having a high-quality bar with 2″ loadable spinning sleeves is the main thing to look for. Compared to standard barbells, Olympic barbells will last for a lot longer, so they are usually worth the extra investment.
