How it works
Subtract the bar, divide by two and fill each side with the largest plates first. That gives the fewest plates to carry. It is the same calculation as the plate calculator in the Liftquill app.
Plate colors
Competition plates follow a color code: red 25 kg, blue 20 kg, yellow 15 kg, green 10 kg and white 5 kg. Pound plates are usually 45, 35, 25, 10, 5 and 2.5 lb.
Questions
How much does the bar weigh?
A standard men’s Olympic bar weighs 20 kg (45 lb) and a women’s bar 15 kg (35 lb). Many gyms also have 10 kg technique bars and lighter fixed bars.
Should I count the collars?
Competition collars weigh 2.5 kg each, but the spring clips in most gyms weigh almost nothing. Most people don’t count them.
What if the weight can’t be loaded exactly?
The calculator shows what is left over. Round to the nearest weight you can load, or use fractional plates if your gym has them.
