Roller Shade Size Guide
DIM roller shades are made to measure in 1/8-inch increments. Use this guide to check that your window fits, then follow our step-by-step how to measure your window guide before you order.
Size ranges
- Free Stop cordless roller shades: 20 to 96 inches wide and 24 to 96 inches tall.
- Motorized roller shades: 22 to 96 inches wide and 24 to 96 inches tall.
Inside or outside mount
- Inside mount: the shade sits inside the window casing and needs at least 2 inches of depth. We automatically deduct 1/4 inch from the width so the shade fits.
- Outside mount: the shade mounts above the window frame and is made to the exact width you order. We recommend at least 2 inches wider than the window opening.
Hardware dimensions
- Cassette valance: 3 inches deep and 3 1/8 inches tall.
- Mounting bracket: 2 1/2 inches long, with 1 1/4 inches to the screw hole.
