Plate & Equipment Calculators
Load the bar correctly, every time. Stop doing mental gym math and save your energy for the lift.
Barbell Plate Loading, Made Simple
Figuring out which plates to load for a target weight is a common source of mental math in the gym — especially when jumping between US standard (lb) and international Olympic (kg) equipment. The RepMaths Barbell Plate Calculator removes that friction completely. Just enter your target weight and bar weight, and it shows exactly which plates to load on each side of the bar.
Whether you are lifting in a commercial gym or building a home gym, our calculators support standard plate sets:
- Kilogram (kg) plates: 25, 20, 15, 10, 5, 2.5, and 1.25 kg
- Pound (lb) plates: 45, 35, 25, 10, 5, and 2.5 lb
Use these equipment tools alongside our 1RM Calculator to plan your top working sets, or the Warm-Up Set Calculator to build a complete, safe ramp-up from the empty bar to your heaviest lift.
