# Set a Total Weight

The total weight of the model can also be specified in advance. If you want to obtain a specific **total weight** you can enter it in grams in the **Weight** field of the **Edit Settings** window available from the [model editor](https://help.pesipiuma.app/en/introduction/editor-interface#import).

* Click the **Edit** button in the left sidebar to open the model settings window.

Once the desired **total weight** is set, Pesipiuma will automatically increase or decrease the coefficients of the pieces so that the total weight matches the value entered.

* If you want to return to the initial situation, set the **Weight** value to `0`.

{% hint style="info" %}
You must **set the coefficients for the pieces with 100 as their base first**, so that the proportion is maintained even after the calculation with the final predefined total weight.

**Example:**

Initial situation:

**`Initial coefficients:`**`Body=100, Sleeves=85, Collar=110`

From the calculation made by Pesipiuma to reach the total weight a 10% increase is required and the new coefficients will be:

**`Coefficients after calculation:`**`Body=110 Sleeves=93.5 Collar=121`
