About this calculator

The total loaded weight of a barbell equals the bar weight plus the plate weight on each side, counted twice — since plates are loaded symmetrically on both sleeves. Standard Olympic bars weigh 20 kg for men's bars or 15 kg for women's bars in kg-based gyms, and 45 lb in US gyms.

Lifters need to account for the bar itself, not just the plates, when reading a loaded barbell — a mistake that's easy to make when doing quick mental math at the rack. This calculator is used by lifters checking their working weight, strength coaches programming loads, and gym-goers converting between plate math and total weight on the bar.
