20 kilo barbells are thicker, and 15 kilo barbells are a little bit shorter. When you have both, it's quite easy to tell. And if you just have one type of barbell in gym, it's more likely that it's gonna be this 20 kilo one.
Comments Section Olympic barbells come in two weights but they are often the same length. Mens are 20kg and women's are 15kg. Women's barbells are the same length but sometimes are usually a few mm thinner on the shaft. The way you identify it is usually a marking at the end of the barbell that says how heavy it is.
Some brands mark a barbell's weight on the very end of the bar — but, when in doubt, check with a trainer to confirm how much it weighs before you start loading on the plates. (Then work on these essential barbell exercises everyone should master.)
Men's vs Women's Barbells
Men's Olympic barbells are generally 7.2 ft long (2.2m) with a 28mm thick bar grip and weigh 45lbs (20kg). But women's Olympic barbells are slightly shorter at 6.6ft (2.01m) long with a 25mm diameter grip and weigh 33lbs (15kg).

The reason why it's so important for you to know the weight of a Smith machine bar is so you know how much you're actually lifting. As a beginner, it's easy to either over or underestimate yourself, and if you have no idea how much that bar weighs, then you are essentially in the dark.

Bench pressing isn't a one-size-fits-all exercise. Factors such as age, gender, fitness level, and training history contribute to the amount you should be able to bench. The average male beginner might aim to bench press 135 lbs. A beginner female, on the other hand, might start with a 65 lbs lift.
A 20kg barbell is often a good starting point for beginners to hone in their technique and is a sensible starting warm-up weight for experienced lifters.

It all depends on the weight of the bar itself and what counterbalancing is used, which you'll be able to find listed on the equipment or by contacting the manufacturer directly. Smith bars can weigh between 4kg-20kg, with most models falling in the 8kg-12kg range.
For example, if a Smith machine's bar is counterbalanced to weigh 15 pounds instead of a typical 45-pound Olympic barbell, and you load 225 pounds of plates onto it, you're effectively lifting 195 pounds (225 lb of plates plus the 15 lb bar, minus the 45 lb standard bar weight).
The weight of a Smith machine bar typically falls somewhere between 6 to 45 lbs, depending on the machine type and design [1]. For example, a counterbalanced Smith machine often has a starting weight of around 15-20 lbs, whereas a commercial Smith machine without counterbalancing can weigh from 6 up to 45 lbs [2].
