How to Cut Ceiling Tiles- A Step-by-Step Guide
Step 1- Measure
- Your ceiling tiles sit on top of the metal framework of your drop ceiling. To account for this, measure the opening in the framing. Add 1″ to the measurement. This will ensure that your ceiling tiles overlap the opening by ½”, allowing them to rest securely on top of the metal framework.
- Always measure both ends of your space. This way, you can confirm whether or not your opening is consistent or tapered.

Step 2- Mark
- Transfer the measurements you found in step one to your ceiling tile using your tape measure and a pencil or marker.
- Using a straight edge, draw a line along where you need to make your cut.




Step 3- Cut
- Place your ceiling tile on a piece of plywood, a workbench, or another surface you don’t mind cutting.
- Cut gently along the line you drew in step two with a sharp razor knife. Only penetrate ¼”-½” of the blade into the tile as you cut.
- Make a second cut following the same line; this time, penetrate the full depth of the blade into the tile.
- Break any remaining connecting between the ceiling tile and the portion you cut off.


Congratulations, you have cut your ceiling tile!
