Sign Customiser now shows measurement labels on the [lightbox](/posts/lightbox/how-to-make-a-lightbox-sign/) 3D preview, so customers can see exactly how big their sign will be as they design it. Width, height, and depth sit alongside the relevant edges of the sign and update in real time whenever the size changes, removing the guesswork when someone is deciding between sizes.

## What’s Changed

- **Live measurement labels on the 3D preview** - Width, height, and depth float next to the matching edges of the lightbox, so customers can see the physical size of the sign while they rotate and customise it
- **Metric, imperial, or both** - Labels respect the customiser’s measurement system setting and can display in centimetres, inches, or both side by side for stores that ship to mixed markets
- **Individually toggleable** - Each dimension can be shown or hidden on its own, so merchants can surface only the measurements that matter for their product — for example, hiding depth on very slim signs
- **Accurate for custom sizes** - The frame-fit custom size branch now feeds the same measurements through to the preview, so bespoke dimensions appear on the labels instead of falling back to the last preset size
