Plate Calculator

Stop doing plate math mid-warmup. Enter your target weight and bar — get the exact plates to load per side, visualized.

Threshold knows what to load before you ask

Your lifts, warmup ramps, and working sets load with the right plates automatically — based on your latest 1RM and today's programmed intensity. Plus your whole training plan, adapted to your recovery.

Supported bars & plates

The calculator uses the most common gym plates and bars. Colors follow IPF competition standards where applicable — blue for 20 kg / 45 lb, red for 25 kg / 5 lb, green for 10 kg / 25 lb, yellow for 15 kg / 35 lb.

Imperial (lb)

Bars: 45 (standard), 55 (powerlifting), 35 (women's), 15 (technique)

Plates: 45, 35, 25, 10, 5, 2.5

Metric (kg)

Bars: 20 (men's Olympic), 15 (women's Olympic), 10 (technique)

Plates: 25, 20, 15, 10, 5, 2.5, 1.25

How the math works

The calculator uses a greedy algorithm — starting from your largest plate, it loads as many as will fit per side, then moves to the next plate size, repeating until the weight is hit. If the exact target can't be made with standard plates (e.g., a 227 lb target with 2.5 lb minimum plates), it shows the closest achievable load and tells you how far short.

For most commercial gym setups, anything ending in .5 (lb) or .25 (kg) may not be achievable without microplates.

Stop doing plate math. Just lift.

Threshold logs your working weights, picks the right plates automatically, and progresses you from set to set. Your coach knows what you lifted last time and what you should lift next.
