Plate calculator

Stop doing bar math mid-session. Enter your target weight and this calculator shows exactly which plates to load on each side of the bar — and rounds to the nearest weight you can actually build if the number doesn't land.

Enter your target weight.

Worked example

For 140 kg on a 20 kg bar you need 60 kg per side: 25 + 25 + 10 kg. The calculator builds that list automatically and flags any target that can't be loaded exactly.

Frequently asked questions

What bar weight does this assume?
A standard Olympic barbell: 20 kg in metric mode, 45 lb in imperial mode. The plate list is per side, so the total is the bar plus twice the plates shown.
What if my target isn't loadable?
The smallest pair you can add is twice the smallest plate (2.5 kg or 5 lb). If a target falls between increments, the calculator snaps to the nearest achievable load and tells you how far off it is.
Which plates does it use?
Standard gym sets: 25/20/15/10/5/2.5/1.25 kg, or 45/35/25/10/5/2.5 lb. It loads greedily from the heaviest plate down, the way you'd load a real bar.
