How it is calculated

The bar is subtracted from the target and the rest is split between the two sides: per side = (target − bar) ÷ 2. The tool then loads plates greedily, largest first, from a fixed set. In kilograms the set is 25, 20, 15, 10, 5, 2.5 and 1.25. In pounds it is 45, 35, 25, 10, 5 and 2.5. A plate size is repeated as long as it still fits in what is left.

It shows the plates for one side only (load the same on the other side), the loaded weight per side and the total achievable weight, bar + 2 × loaded per side. If the target cannot be built exactly from this set, the achievable weight is the closest value below the target. If the bar field is empty, the bar defaults to 20 kg or 45 lb. A target below the bar weight, or above 10,000 (kg or lb), returns no result. Collars and any non-standard plates are not included.

Worked example

Target 142.5 kg on a 20 kg bar. Per side = (142.5 − 20) ÷ 2 = 61.25 kg. Greedy loading: 25 fits, leaving 36.25; 25 fits again, leaving 11.25; 20 and 15 are too big, 10 fits, leaving 1.25; 5 and 2.5 are too big, and 1.25 fits exactly. The plates are 25 + 25 + 10 + 1.25, which is 61.25 kg per side. Total = 20 + 2 × 61.25 = 142.50 kg, so the target is reached exactly.

Common mistakes

  • Loading the whole plate list on one side: the result is for a single side, so a bar with 25 + 25 + 10 + 1.25 on the left needs the same on the right.
  • Entering the weight of the plates per side as the target: the target is the total including the bar, and the bar is subtracted automatically.
  • Leaving the unit on kg while thinking in pounds: 225 with kg selected means 225 kg, and the plate list will be completely different. Choose lb for pound plates.
  • Forgetting that the bar is not always 20 kg or 45 lb: women's, training and technique bars are lighter, so enter the real bar weight or the total will be off.
  • Expecting an exact total for any target: with the smallest plate of 1.25 kg per side, a target of 101 kg on a 20 kg bar comes back as 100.00 kg achievable, so check the achievable line.

About this calculator

Loading a barbell to an exact target weight means working out which combination of plates, added symmetrically to each side, gets you there — a small puzzle every lifter solves at the rack. The bar itself has a fixed weight (typically 20 kg or 45 lb for a standard Olympic bar), so the remaining weight must be split evenly between the two sides and built from the plate sizes available in a standard set (the tool uses 25/20/15/10/5/2.5/1.25 kg or 45/35/25/10/5/2.5 lb).

This calculator takes your target weight, bar weight, and unit and works out the plates to load per side using a greedy largest-plate-first approach, the same logic lifters use instinctively. It's a practical tool for strength trainees, powerlifters, and gym-goers loading a barbell for squats, deadlifts, or bench press, especially useful when jumping to an odd target weight or working with an unfamiliar gym's plate inventory.

    The plate list assumes your rack holds every size in the set, including the small 1.25 kg plate. If your gym stops at 2.5 kg, the real total only moves in steps of 5 kg over the bar, so round your target to that before trusting a loading that ends in 1.25. In pound mode the smallest plate is 2.5 lb, which means 5 lb jumps in total. Which plate size is missing from the rack where you train?
