Most fitness equipment listings describe products in marketing terms. Competition rulebooks do the opposite: they state dimensions and tolerances in numbers. The International Powerlifting Federation (IPF) publishes such figures for the bars, discs, racks and benches used at its championships, and they give buyers a precise benchmark for reading any manufacturer’s specification sheet. This article summarises the equipment section of the IPF Technical Rulebook effective 1 March 2026. These are competition rules for IPF events, not consumer safety standards, and other federations publish their own rulebooks.
How the rulebook treats approved equipment
The IPF’s Approved List page states that bars and plates, squat racks, bench racks and benches from commercial manufacturers registered and approved by its Technical Committee are permitted at World, Regional and Continental Championships, and that the list published there is valid through 31 December 2026. The rulebook itself adds that only approved bars and discs may be used at IPF World Championships or for setting world records, and that bars used at IPF championships must not be chromed on the knurling.
The bar
The 2026 rulebook requires a straight, well-knurled and grooved bar that conforms to these dimensions:
- total overall length not exceeding 2.2 m;
- distance between the collar faces not exceeding 1.32 m or less than 1.31 m;
- shaft diameter not exceeding 29 mm or less than 28 mm;
- combined weight of bar and collars of 25 kg;
- sleeve diameter not exceeding 52 mm or less than 50 mm;
- machined diameter markings spaced 81 cm apart.
The discs
Disc rules are where competition equipment differs most from typical consumer plates. The rulebook requires that:
- every disc weighs within 0.25 per cent or 10 grams of its face value, so a 20 kg disc must weigh between 19.95 kg and 20.05 kg, and a 1.25 kg disc between 1.24 kg and 1.26 kg;
- the centre hole is between 52 mm and 53 mm;
- discs come from a permitted range of 1.25, 2.5, 5, 10, 15, 20 and 25 kg;
- discs of 20 kg and over are no more than 6 cm thick, and discs of 15 kg and under no more than 3 cm thick;
- the largest discs are no more than 45 cm in diameter;
- colours follow a code: 15 kg yellow, 20 kg blue, 25 kg red, with any colour for 10 kg and under.
The rulebook also specifies collars, which must always be used and must weigh 2.5 kg each.
Scales and the lifting platform
The rulebook sets equipment beyond the bar. Scales must be electronic, register to two decimal places, weigh up to 180 kg and have a calibration certificate valid within one year of the competition. The platform must measure between 2.5 m by 2.5 m and 4.0 m by 4.0 m, be no more than 10 cm high, and be flat, firm, level and covered with non-slip smooth carpet. Rubber matting or similar sheeting is not permitted on the competition platform.
Squat racks
Squat racks must come from approved commercial manufacturers, adjust from a minimum height of 1.00 m at the lowest position to at least 1.70 m in 2.5 cm increments, and be capable of being secured at the required height by pins.
Benches and bench racks
The bench specification is the most detailed and the most transferable to consumer comparison. The rulebook requires:
- bench length not less than 1.22 m, flat and level;
- width of at least 29 cm and no more than 32 cm;
- height of at least 42 cm and no more than 45 cm from floor to the top of the uncompressed pad;
- adjustable uprights with a bar rest height between 75 cm and 110 cm;
- a minimum width of 1.10 m between the insides of the bar rests;
- a bench head extending 22 cm beyond the centre of the uprights, with a tolerance of 5 cm either way;
- attached safety stands in all events, at least 50 cm high, with ten holes in 2.5 cm increments and 50 cm in length.
Using the figures as a buying benchmark
A buyer comparing home benches and racks can hold a product’s published dimensions against these numbers: pad width and height, upright range, width between bar rests and safety-stand height and adjustability. A rack that adjusts in wider steps than 2.5 cm, or a bench whose pad is well outside the 29 to 32 cm width, is not wrong for home use, but it differs from the competition specification. Products described as “competition” or “calibrated” should state the tolerance they meet.
Frequently asked questions
Do these figures apply to home gym equipment?
They apply to equipment used at IPF championships. They are useful as a benchmark, but a home product is not required to meet them.
Why are disc tolerances so tight?
The rulebook requires that discs weigh within 0.25 per cent or 10 grams of face value, so that loaded weights are accurate for records.
The bottom line
The IPF rulebook effective 1 March 2026 supplies concrete numbers for bars, discs, collars, racks and benches, including a 28 to 29 mm shaft, 50 to 52 mm sleeves, disc tolerances of 0.25 per cent or 10 grams, and a bench 29 to 32 cm wide and 42 to 45 cm high. These do not certify any home product, but they give buyers a factual yardstick for comparing specification sheets.
