# How to Configure Custom Page Sizes

Use custom page sizes when standard page layouts do not match your output.

This is useful for mailing labels, business cards, letterhead, and international paper formats.

### Set a custom page size

{% stepper %}
{% step %}

### Open page settings

Open the **Page Settings** tab in the Template Editor.
{% endstep %}

{% step %}

### Switch to a custom layout

Set **Page Layout** to **Custom**.
{% endstep %}

{% step %}

### Enter the page dimensions

Set **Page Width** and **Page Height**.

Choose the unit that matches your dimensions.
{% endstep %}

{% step %}

### Adjust margins

Set the top, bottom, left, and right margins.

Use smaller margins only when your printer supports them.
{% endstep %}

{% step %}

### Save and test

Save the template.

Generate a test document before rollout.
{% endstep %}
{% endstepper %}
