IWF Color Standards

In international weightlifting, each plate weight has a designated color: red for 25 kg, blue for 20 kg, yellow for 15 kg, and green for 10 kg. Smaller change plates have their own colors too. Plate Math uses these exact colors in its visual plate display, so the plates you see on screen match the plates on your bar.

KG Bar Options

The standard Olympic barbell is 20 kg, but women's bars are 15 kg and some training bars vary. Plate Math lets you set your bar weight so the calculation is always accurate for your setup. The math adjusts automatically — just change the bar weight in settings.

Switching Between Units

Some lifters track in both pounds and kilograms — maybe you train at a KG gym but follow a program written in pounds. Plate Math lets you switch units freely. Your plate inventory stays separate for each unit system, so you can configure both and swap without losing your setup.

FAQ

How do I calculate plates in kilograms?

Same method as pounds: subtract the bar weight (usually 20 kg) from your target, then divide by 2. For example, 100 kg total: 100 − 20 = 80 kg of plates, divided by 2 = 40 kg per side (two 20 kg plates per side).

What are the IWF plate colors?

Red = 25 kg, Blue = 20 kg, Yellow = 15 kg, Green = 10 kg. Smaller plates: white = 5 kg, black or other colors for 2.5 kg, 2 kg, 1.5 kg, 1 kg, and 0.5 kg.
