What causes Unity subtitles clipping at larger text sizes?

The subtitle TMP element sits in a fixed-size box, so when the player raises the text-size setting the words overflow the box and get clipped.

How do I catch this when it only happens for some players?

Capture it automatically from the player's device with the full stack trace, the device and OS, the build, and a breadcrumb trail of what they did. That turns a vague complaint into a specific, reproducible issue you can fix without owning the hardware it happens on.

How to Fix Unity Subtitles Clipping When Text Size Increases

Quick answer: Place subtitle text in a Content Size Fitter with vertical layout and word wrap so the container grows with the text size instead of clipping it.

Bigger subtitle text that gets cut off helps no one. A flexible container fixes it. Here is how.

How to fix it

1. Use a Content Size Fitter

Add a ContentSizeFitter with vertical fit set to Preferred Size on the subtitle container so it expands to fit the current font size.

2. Enable word wrapping

Turn on word wrapping in the TMP component and anchor the box from the bottom so it grows upward and stays within the safe area.

3. Rebuild on change

Call LayoutRebuilder.ForceRebuildLayoutImmediate after changing text or size so the layout updates immediately rather than on the next frame.

Catching the ones you can't reproduce

The hardest version of this to fix is the one you can't reproduce — it only happens on a player's hardware, OS, driver, or save state, under conditions that simply aren't present on your machine. A report that says “it crashed” or “it froze” gives you nothing to act on, so the bug survives release after release while quietly costing you players.

Automatic error capture closes that gap. Each failure arrives with its full stack trace, the device and OS, the build number, and a breadcrumb trail of what the player did right before it broke, so even a failure you have never seen becomes a specific, reproducible issue. Fold identical failures into one signature ranked by how many players each hits, and your worklist sorts itself worst-first instead of arriving as a stream of vague complaints.

This is where a tool like Bugnet earns its place. Its SDK captures every Unity error automatically with the full stack trace plus device, OS, memory, build, and game-state context, folds duplicates into one grouped issue with an occurrence count, and ties each to the build it first appeared on — so you fix the problem that hurts the most players first and confirm it is gone when its signature disappears from the next release.

Ship the fix, watch the signature disappear from the next build. That's how you know it's really gone.
