How Much Does a Barbell Weigh? All Common Bar Types

Quick Answer: A standard Olympic barbell weighs 45 lbs (20 kg). A women’s Olympic bar weighs 33 lbs (15 kg). Powerlifting and deadlift bars also weigh 45 lbs but differ in stiffness and length. Squat bars are heavier at 55 lbs (25 kg). Training bars run 5–15 lbs.

---

Every barbell in a gym looks like a steel rod with sleeves on each end. Most of them weigh 45 lbs. But “most” isn’t “all,” and the exceptions matter more than people expect.

A deadlift bar and a squat bar both look like 7-foot steel rods, but one weighs 45 lbs and the other weighs 55 lbs. A training bar looks like a regular barbell but weighs 10 lbs. A safety squat bar with its pads and handles can hit 70 lbs before you add a single plate. If you’re tracking progressive overload, every one of those differences changes what your training log actually says about your strength.

How Much Does a Standard Olympic Barbell Weigh?

A men’s Olympic barbell weighs 20 kg (44.1 lbs, rounded to 45 in the imperial system). It runs 2.2 meters (7.2 feet) long with a 28mm shaft diameter and rotating sleeves that accept 2-inch Olympic plates.

This is the bar the International Weightlifting Federation (IWF) sets as the competition standard for the snatch and clean & jerk. The IWF’s Technical and Competition Rules specify the exact dimensions, materials, and manufacturing tolerances, bars must fall within +0.1% to −0.05% of the stated weight (IWF, 2025). Every competition bar worldwide matches these specs.

Outside of competition, the same 20 kg / 45 lb standard carries into commercial gyms, CrossFit boxes, and home gyms. If you see a 7-foot bar on a squat rack with 2-inch sleeves, it almost certainly weighs 45 lbs.

Olympic bars are built with whip, the shaft flexes under heavy loads. That flex helps during cleans and snatches because the plates break off the floor before the bar finishes bending, giving the lifter a mechanical timing advantage. If you’re not doing Olympic lifts, a stiffer powerlifting bar is a better fit.

How Much Does a Women’s Barbell Weigh?

A women’s Olympic barbell weighs 15 kg (33 lbs). It’s shorter at 2.01 meters (6.5 feet) and uses a 25mm shaft instead of 28mm.

The thinner shaft isn’t about strength capacity, it’s about grip. A 25mm bar fits smaller hands better, which means a more secure hold during fast, technical lifts like snatches and cleans. Despite the name, these bars work for anyone with smaller hands, including teenage athletes and lighter adults who find a 28mm shaft uncomfortable.

You can identify one by the collar markings: women’s Olympic bars carry yellow rings near the sleeves, while men’s bars carry blue. If there are no markings, grip the shaft — if your thumb and fingers overlap easily, it’s the thinner 25mm women’s bar.

How Much Does a Powerlifting Bar Weigh?

A powerlifting bar weighs 20 kg (44–45 lbs), same as an Olympic bar on paper, but built for a different purpose. The International Powerlifting Federation (IPF) specifies a shaft diameter between 28–29mm and a combined bar-and-collar weight of 25 kg (IPF, 2026).

The key difference is stiffness. A powerlifting bar has almost no whip, the shaft doesn’t flex under load. That rigidity is what you want for squats, bench press, and deadlifts, where bar stability matters more than the timing advantage whip provides.

Powerlifting bars also have aggressive knurling and center knurling. The center knurl keeps the bar from sliding down your back during squats. If a bar has center knurling and a stiff feel, it’s a powerlifting bar — not an Olympic bar.

How Much Does a Deadlift Bar Weigh?

A deadlift bar weighs 44–45 lbs (20 kg), but everything else about it is different from a powerlifting bar.

Deadlift bars are longer (7.4–7.7 feet vs 7.2 feet standard) with a thinner shaft (27mm vs 28–29mm). Both changes increase whip. On a heavy pull, the bar bends and the inner plates break the floor before the outer plates do, meaning you’re not lifting the full load all at once. That mechanical advantage is why deadlift bars are used in meets that allow them.

The knurling is aggressive with no center knurl (keeping the bar from scraping your shins), and the sleeves are shorter to concentrate the weight closer to the hands. If a bar flexes noticeably when you pull 315+ lbs, it’s a deadlift bar.

How Much Does a Squat Bar Weigh?

A squat bar weighs 55 lbs (25 kg), heavier and thicker than a standard barbell.

The shaft diameter jumps to 32mm (vs 28mm standard), and the total length extends to 7.7–8 feet. Both changes serve stability: the thicker shaft spreads the load across your upper back more evenly, and the complete lack of whip means the bar stays rigid under maximal squat loads. Center knurling is wider than on a powerlifting bar, covering more shaft where it contacts your back.

This is a specialty bar. Most commercial gyms don’t stock it — it’s mainly found in powerlifting-focused facilities. If you’re squatting under 400 lbs, a standard 45 lb powerlifting bar handles the job.

How Much Does a Standard (1-Inch) Barbell Weigh?

Standard barbells with 1-inch sleeves weigh 15–25 lbs (7–11 kg). They run 5–6 feet long and accept standard plates with a 1-inch center hole, not the 2-inch Olympic plates used on every bar listed above.

These are the bars included in home gym starter kits, body-pump classes, and budget setups. They’re lighter, cheaper, and have lower weight capacity (typically under 200 lbs). If you’ve already bought Olympic plates, they won’t fit on a standard bar, the sleeve diameters are incompatible.

For anyone training seriously or planning to add weight over time, an Olympic bar is the better investment from the start.

How Much Does a Training or Technique Bar Weigh?

Training bars weigh 5–15 lbs (2.5–7 kg). They’re typically aluminum or lightweight steel, run 4–6 feet long, and max out at 40–200 lbs of capacity.

These bars exist for one purpose: learning movement patterns without load. They’re used with youth athletes, rehab patients, and anyone practicing Olympic lift technique before adding real weight. They’re not built for working sets, they’re built for movement quality. Coaches also use them as warm-up tools before transitioning athletes to a full 45 lb bar.

Specialty Bars at a Glance

Some bars don’t fit the standard categories. Here are the specialty types you’re most likely to encounter:

Safety Squat Bar (SSB): ~70 lbs (32 kg). Padded yoke sits on your shoulders with handles jutting forward. The load shifts your center of gravity forward, forcing your core and upper back to work harder. Built for lifters with shoulder mobility issues who can’t hold a straight bar behind them.

Bench Press Bar (Cambered): ~60 lbs (27 kg). A bar with a 4–6 inch bend in the shaft. The curve lowers the plates’ center of gravity and reduces wrist strain during heavy bench pressing. Roughly 8 feet long — longer than a standard bar.

Axle Bar: 44–55 lbs (20–25 kg). A 2-inch thick shaft with no rotating sleeves. The fat grip makes every pulling movement harder and is a staple in strongman training for building raw grip strength.

Tricep Bar: ~22 lbs (10 kg). A short bar (~3 feet) with two parallel handles inside a square frame. Designed to reduce wrist stress during tricep extensions and close-grip pressing movements.

Bamboo/Stability Bar: ~6 lbs (2.7 kg). A flexible bar that wobbles under load, forcing your stabilizer muscles to work throughout the lift. Can handle up to 300 lbs despite its light weight. Used for warm-ups, rehab, and stability-focused training.

Fixed (Preloaded) Barbell: 20–115 lbs (9–52 kg). Straight or EZ-shaped bars with rubber-coated plates permanently attached. The number stamped on the end IS the total weight, bar plus plates combined. You’ll find these on a dedicated rack in most commercial gyms, organized by weight in 10 lb increments.

How Much Do EZ Curl Bars, Hex Bars, and Smith Machine Bars Weigh?

These three bar types vary so widely across brands that each has its own detailed guide on ExerciseMenu:

EZ Curl Bars: 10–30 lbs depending on standard, Olympic, super, rackable, or fixed-weight model. A Titan Olympic EZ bar weighs 14 lbs, while a Rogue weighs 30 lbs. For the complete brand-by-brand breakdown with 16 models compared, see our EZ curl bar weight guide.

Hex/Trap Bars: 44–65 lbs depending on closed, open, or rackable frame design. A CAP hex bar weighs 45 lbs, a Kabuki HD weighs 65 lbs. For the full comparison with 15 brands, see our hex bar weight guide.

Smith Machine Bars: 15–35 lbs depending on the counterbalance system. A counterbalanced bar can feel as light as 15 lbs, while a non-counterbalanced bar sits closer to 30–35 lbs. For specs by machine type, see our Smith machine bar weight guide.

Is a Barbell 44 or 45 Pounds?

Technically, 44.09 lbs. The IWF standard is exactly 20 kg, which converts to 44.09 lbs, not 45.

The rounding happened because barbells and standardized weight plates were designed in Europe during the early-to-mid 20th century using the metric system. A 20 kg bar plus two 20 kg plates plus two 2.5 kg collars = 65 kg, clean, simple math. When the United States adopted the barbell, 44.09 lbs didn’t work for quick plate math, so the industry rounded to 45.

Both numbers are functionally correct for training. The distinction only matters in competition settings where bars and plates are calibrated in kilograms to within 0.1% tolerance. For everyday training, pick one number and use it consistently across every session so your log stays comparable.

Do You Count the Bar Weight?

Yes. The bar is part of the load your body moves. Leaving it out makes every number in your training log wrong.

Common loading totals with a 45 lb bar:

Plates Per Side	Plate Weight	Bar Weight	Total
1 × 45 lb	90 lbs	45 lbs	135 lbs
2 × 45 lb	180 lbs	45 lbs	225 lbs
3 × 45 lb	270 lbs	45 lbs	315 lbs
4 × 45 lb	360 lbs	45 lbs	405 lbs

What about collars? Standard gym spring clips weigh roughly 0.5 lbs total for the pair — most lifters ignore them. Metal lock-jaw collars add 1–2 lbs. In competition, IPF-spec collars weigh 2.5 kg (5.5 lbs) each and ARE counted in the total — the bar-plus-collars unit weighs 25 kg before any plates go on.

FAQs

If you’re new to barbell training or returning after a break, start with the empty bar and add weight in small increments. If you have pain or mobility limitations, consult a doctor or physiotherapist before loading.
