Plate Calculator

Work out which plates go on each side of the bar for the weight you want to lift, using the bars and plates you actually own.

---

Set up your plates

1. Open the Equipment section: on the web it is at the bottom of the Exercises page; in the mobile app it is Library > Equipment > Plates & bars.
2. Pick Use kg plates or Use lb plates to start from a standard set, so you do not have to type anything:
   • kg: 25, 20, 15, 10, 5, 2.5, 1.25 and 0.5, with a 20 kg bar (plus a 15 kg women's bar, an EZ bar and a trap bar).
   • lb: 45, 35, 25, 10, 5, 2.5 and 1.25, with a 45 lb bar (plus a 35 lb women's bar, an EZ bar and a trap bar).
3. Change how many pairs of each plate you have. A pair is one plate for each side. Set a size to 0 pairs to leave it unused.
4. Add odd plates, such as 1 kg plates or 0.25 kg change plates, with Add plate. Weights can have up to three decimals.
5. Edit the bars you own: name, weight and type (barbell, women's bar, EZ bar, trap bar or other).
6. Switch on Collars count if the collars you use weigh something, and enter the weight of one collar.

Plates are measured in the unit you pick for the inventory. If your app is set to another unit, the calculator converts the target weight exactly and tells you the result in the inventory's unit.

Using the calculator

For a barbell, EZ bar or trap bar exercise, open the Plates action while you log a set:

• Mobile: in the live workout, use Plate calculator in the set menu (the menu a set number opens), or Calculator on the keyboard bar while the weight is selected; in the set editor use the plates button next to the weight.
• Web: open the workout in the workout player on the Diary, then use the dumbbell button on a set's row.

You see the bar weight, the plates for each side (heaviest first) and the total. Pick another bar if the suggested one is not the one you are using.

If the weight cannot be built with your plates, nothing is rounded for you. The calculator shows the nearest weight you can load below and above the target and how far each one is from it.

The calculator finds every weight your plates can make, so it still gets it right when you own only one pair of a size, or have unusual plates. It uses the fewest plates, and the heaviest plates first when there is a choice.

Sharing

The plate inventory is private to you: nobody you share your diary with can read or change it. Someone logging workouts on your behalf sees the calculator with the standard preset for your weight unit instead of your own plates.
