Hevy’s Weight Plate Calculator
The plate calculator, also known as a barbell calculator, helps you figure out what weight plates you need to add to a bar to achieve a specific weight.
It provides recommendations based on:
- The target weight
- Your available weight plates
- The bar’s weight
For instance, if you want to lift 120 kilograms, your bar weighs 20 kilograms, and you have 2.5, 5, 10, and 15-kilo plates, the calculator determines the best option:

How to Use the Plate Calculator
Step 1: Enable in Settings
Make sure you’ve enabled the feature in your workout settings by scrolling to the bottom of a workout and selecting the grey Settings button or navigating to the app settings (Profile tab > gear icon on the top right > Workouts > Plate Calculator > enable via toggle button).
Step 2: Add a Barbell Exercise to a Workout
Start a new session (be it from an existing routine or an empty workout) and add any barbell, short bar, or EZ bar exercise.

Step 3: Add Target Load For a Set
Write your load target for each set in the fields under the KG or LBS column (depending on the units you’ve selected).

Step 4: Tap ‘Calculator’
Tap the Calculator button on the bottom left, just above the keyboard. Then, select your available weight plates and the bar’s weight.

Step 5 (Optional): Manage Your Available Equipment
With the barbell calculator open, you can tap Manage next to Available Equipment to customize your available options.

This is particularly useful if you work out at home or in a small gym with limited equipment. You can add additional bar and custom plate options with specific loads.
