Plate Loading Calculator
Enter a target weight and pick your bar. This loads each side for you, then tells you exactly which plates you are missing. It counts the bar so you do not have to.
This tool loads lb plates, the common set in the US. Enter your target in lb or kg; a kg target is converted, and the total shows both.
How it works
The calculator subtracts your bar weight from the target, halves the remainder, and fills each side from the heaviest plates you own. It never suggests plates you do not have, and when your set cannot reach the target it names the exact gap in pounds. Bar weight matters more than beginners expect. A standard 6 foot bar weighs about 15 pounds and a full Olympic bar 45, so loading 135 is very different plate math on each. Our own bars carry their real weighed numbers in the Basalt Ledger, so the number you enter here can be the true one.
One worked example. To load 225 on a 45 lb Olympic bar, subtract the bar (225 minus 45 is 180), then halve it (90 per side). Ninety pounds a side is two 45 lb plates. That is why lifters call 225 "two plates." The calculator does this for any target and any bar, and it uses only the plates you actually own.
Common loads on a 45 lb Olympic bar
Tap any load to send it to the calculator. Per-side figures assume a standard 45 lb Olympic bar.
| Total | Per side | |
|---|---|---|
| 95 lb | one 25 | |
| 135 lb | one 45 | |
| 185 lb | 45 plus 25 | |
| 225 lb | two 45s | |
| 315 lb | three 45s | |
| 405 lb | four 45s |
The short answers
How much does a barbell weigh
A full Olympic bar weighs 45 lb, a women's Olympic bar 33 lb, and typical 6 foot standard bars 14 to 16 lb. Check your actual bar, because budget bars vary; ours are published in the Ledger.
How do I load 225 on a barbell
With a 45 lb Olympic bar, 225 is two 45 lb plates per side. With a 15 lb standard bar you would need 105 lb per side, which most standard sets cannot reach.
Do you count the bar weight
Yes. The total weight lifted includes the bar. This calculator counts it by default; toggle to plates-only if you just want the plate math.
What plates should a beginner buy first
A pair each of 25, 10, and 5 lb plates covers the most common early loads on any bar. Add 45s once you pass roughly 135.

Our standard bar number is measured, not labeled. See the Ledger. Working from percentages? Use the one rep max and training percentage calculator, then load the result here. Before you buy plates, read 1 inch vs 2 inch bars and plates to make sure your plates fit your bar, and what plates do I need for the starter set, then shop plates.
