How much do empty barbells weigh?

  • I have recently noticed that in my gym they have two different sizes of barbells. The difference between them is only in length, but not in diameter. the reason why I'm mentioning that is because I was doing some research and found out that standard bars, which usually weigh about 35 pounds, have a smaller diameter, but These shorter bars have the same 2" diameter as the longer bars, so do they also weigh 45 pounds?

    A barbell weighs as much as it weighs. I've seen 45, 40, and 22 pounders. I worry that this is what SE calls a "how long is a piece of string" question.

    Yes, there are also standard 35 pounders, not to mention the metric versions (20, 15, and 8 kg). The standard Olympic-sized bars that most gyms (in the US) carry are 45 lbs.

    If there's a scale in your gym, why not just measure it yourself?

  • Olympic Bars

    The IPF (International Powerlifting Federation) and the IWF (International Weightlifting Federation) have set forth standards for what a barbell has to be for use in competition. These standards are largely compatible, so most manufacturers will manufacture for those standards:

    • Men's bar: 20kg (~45lb)
    • Women's bar: 15kg (~35lb)
    • Junior's bar: 10kg (~25lb)

    Basically the bar is specified in kg, but it is close enough to the weight I listed in pounds that we use that number when loading the bar with plates in imperial measurements. NOTE: some manufacturers of cheaper Olympic style bars don't follow the standards, and sell a 35lb bar as a men's bar. Check your reviews if you are ordering from the major consumer fitness chains.

    All three official bars use the same standard sleeve size, meaning the plates are interchangeable for all three bars. The Junior's bar is a little shorter than the other two.

    The main differences between a powerlifting bar and a weightlifting bar are:

    • Knurl spacing. The differences are for official snatch grip width vs. official bench press width.
    • Bearings vs. bushings in the collars. Both collars spin, but needle bearings allow a better spin so it is easier to use in Olympic weightlifting movements.
    • Thickness. The thicker the stiffer, and powerlifters like a bit stiffer than Olympic lifters.

    Standard Bars

    Standard bars were never meant to be used in competition, so they have much more variances. They are commonly 20lbs, have no spin, and many don't even have knurling. However, even the weight listed here might not be true for all standard bars.

    When in doubt, weigh the bar on a scale.
