How Do I Measure Before I Place My Order?

Decide if you want an inside mount or an outside mount before you begin the measuring process. A steel measuring tape is much more accurate than cloth measuring tape. Always measure to the nearest 1/8 inch. Don’t round to a half or whole inch. Be careful about transposing measurements. Be sure to always have width and height clearly marked. And remember: Always put your width measurement first, and height last (W x H). Then read our Measuring Guide.
