# Width or Height is set to 500 but the image sizes itself automatically

**What you are seeing**

Width or Height is set to 500 but the image sizes itself automatically

---

## Why it happens

500 was a legacy sentinel meaning 'auto-size', so a macro saved with 500 behaves as if the field were blank.

---

## What to do

Use 499 or 501 if you genuinely need roughly that size, or set the other dimension instead.

## A few things that catch people out

* Value 500 in Width or Height is ignored. It was a legacy sentinel meaning 'auto-size', so a macro saved with 500 behaves as if the field were blank.
