Question
What is the difference between 4mm Coroplast and 10mm Coroplast?
Answer
The 4mm and 10mm labels both refer to the thickness of the coroplast sheet, measured in millimeters. The larger the number, the thicker and more rigid the board.
| Flute | Approx. thickness | Feel |
|---|---|---|
| 4mm | about 3/16 inch | lightweight, standard yard-sign gauge |
| 10mm | about 3/8 inch | thicker and stiffer for larger or higher-traffic signs |
For most yard signs and directional signage the 4mm is plenty, while 10mm is worth choosing when you want extra rigidity on bigger formats.
