Barbell plate calculator.

Calculate the plates needed on each side of a barbell for a target load in kilograms or pounds.

DIRECT ANSWER

Enter the target barbell weight, bar weight and unit. The plate calculator subtracts the bar, divides the remainder between both sides and returns a loadable combination from standard plate sizes or says when the target cannot be matched exactly.

CALCULATOR

Load the bar

The result lists plates for one side. Mirror it on the other.

Unit
2515

Exact target: 100 kg.

Load both sides equally

The result lists plates for one side of the bar. Load the same combination on the other side and use collars where appropriate.

Available plates matter

The default calculation assumes common plate denominations. A real gym may have different plates, so treat an unavailable denomination as a reason to choose the next loadable target.
