How Many Plates Is 135, 225, 315 and 405?

When lifters talk about "plates", they mean 45 lb plates on each side of a 45 lb Olympic bar. One plate is 135 lb, two plates is 225 lb, three plates is 315 lb and four plates is 405 lb. Each extra 45 on both sides adds 90 lb to the bar.

These numbers come up so often because they look great on a bar. A clean row of big plates is the gym equivalent of a perfectly organized bookshelf. Nobody brags about benching 210.

The formula

Total weight = bar + (plates on one side × 2). For a target weight, flip it around: subtract the bar, then divide by two to get what goes on each side. For 275 lb: 275 − 45 = 230, divided by 2 = 115 lb per side, which is 45 + 45 + 25.

Loading chart in pounds

With a 45 lb bar, loading the heaviest plates first.

If your gym has no 35s, use 25 + 10 instead. If it has no 2.5s, blame management.

Loading chart in kilograms

With a 20 kg bar and standard competition plates.

In kilo gyms, people talk in "reds" instead of plates: 140 kg is "two reds and a green", because 25 kg plates are red and 10 kg plates are green.

Plate colors

Kilogram colors are a competition standard. Pound bumper colors are a common convention, but iron plates and some brands don't follow it, so always read the number on the plate.

Plate etiquette

• Unload your bar. Leaving 4 plates on the leg press is not a flex. It's a chore you gave to a stranger.
• Load evenly. Take plates off one side at a time and the bar can tip. Alternate sides.
• Use collars on squats and overhead work, so plates don't slide off when the bar isn't perfectly level.
