The formula
per side = (target − bar) ÷ 2
Each side takes as many of the largest plate as fit, then the next size down. Anything smaller than the smallest plate is reported as a remainder.
What to watch out for
Choose kilograms or pounds, and the plates you have. Enter the target and bar weights in that unit. Check the bar too, since not every gym bar weighs the standard amount.
Collars are not counted here. Competition collars weigh 2.5 kg each, so take them off the target if you use them.
