How To Use The Barbell Calculator?

The barbell calculator we created here at FitDominium is very easy to use, just put in your desired target weight, and the plate calculator will generate an infographic of a barbell with the proper weight plate configuration to reach the total weight.

We assume that you have every plate weight quantity available by default. If you are limited in terms of your weight plates, just click on the “Set Plates Available” button and set the number of plates you have.

What If I Use The Metric System?

If you use metric kilogram plates, just select the checkbox at the top and the calculator will now generate using typical KG plates (20, 15, 10, etc.).

What If My Bar Does Not Weigh 45 Pounds or 20kg?

If you are using a specialty barbell like a Swiss bar, trap bar, or safety squat bar, chances are that the bar does not weigh exactly how much a standard Olympic barbell weighs.

You can just tell us how much the bar weighs, and that will be taken into account when we do the math and make the barbell infographic.

You can typically tell by looking at the side of the bar or the manufacturer’s website but here are some typical weights for different types of barbell.

  • 65 lb – Safety Squat Bar
  • 55 lb – Buffalo Bar
  • 45 lb – Olympic Bar
  • 25-45 lb – Swiss Bar
  • 45 lb to 75 lb – Trap Bar
  • 35 lb – 6′ Olympic Bar
  • 17 lb or 25 lb – EZ Curl Bar

What If I Put In A Number That Cannot Be Racked?

This calculator assumes that the lowest possible weight plates you have are 2.5 lbs and 1.25 kg, respectively. If you input a weight that cannot be loaded onto a barbell with these plates, then we will round up to the nearest multiple of 5 and show you the barbell for those weights.
