Weight Bar Calculator
Find out exactly how much weight is on any barbell. Enter a target or count plates already loaded. Works in kg and lb instantly.
Direct Answer
A weight bar calculator includes the bar weight and the plates on both sides to show the full loaded total.
Total = bar + 2 x one-side plate stack
One 45 each side
135 lb
45 lb bar
Two 45s each side
225 lb
45 lb bar
Two 20 kg each side
100 kg
20 kg bar
Target mode and reverse mode
If you know the target, use standard mode. If the plates are already on the bar, use reverse mode and tap one sleeve.
Common bars
The most common bars are 45 lb, 20 kg, 35 lb, and 15 kg, but specialty bars can be heavier or lighter.
Frequently asked questions
Does the bar count in the total?
Yes. Barbell totals include the bar. If you ignore the bar, every plate calculation will be off by 45 lb, 20 kg, or whatever your actual bar weighs.
What if I only know the plates on one side?
Double the one-side plate stack and add the bar weight.
Need a custom number?
Use the live calculator when your bar weight, unit, or plate inventory is different.
