Letterbox & House Sign/Number Size Match Guide

Every Dagood letterbox has different front panel sizes. Choosing the right address decal, custom sign, or house numbers helps your letterbox look balanced and easy to read.

This guide shows which standard Dagood decal, sign, and number sizes suit each model.

All measurements are width × height (mm).

How to Use This Guide

1. Find your letterbox model below.
2. Match your usable panel area to the recommended decal/sign/number sizes.
3. If you’re unsure, send us a photo of your letterbox and we’ll confirm sizing.

Note: Slatted panels (like Clasti and Plaza II) are suitable for signs and numbers only (not decals).

Placement tip: On most freestanding letterboxes, we recommend placing signage on the top chute/upper panel for the cleanest proportions and visibility. (Apex is the main exception — its larger bottom panel also works well.)
