How To Measure for Graber Blinds

• Measure each individual window because size differences are common.
• Record width first, then height (or length) to the nearest 1/8 inch.
• Measure window's width from left to right and height from top to bottom. Use a steel tape measure. Don't use a cloth tape as cloth tapes may stretch and give you an inaccurate measurement .

Horizontal Blinds and Fabric Shades (Includes Innovative Shadings, Solar Shades)

Inside Mount:

• For an Inside Mount, blinds and shades are installed inside the window casing. Minimum depth requirements vary (some price lists and reference materials may also refer to an inside mount as IB).
• Measure the inside width of window casing precisely from one inside edge to the other in 3 different places. Keep the narrowest measurement.
• Measure the height precisely in three different places from the top edge of the opening to the top of the sill. Keep the longest measurement.
• Do not make any deductions for clearance. The factory will the take necessary deductions for a perfect fit.
• Measure the window diagonally in two places, as per the picture to the right. If the two diagonal dimensions are not the same, an outside mount application is recommended for optimal shade function and aesthetics.
• Solar Shades: On Continuous Loop inside mounts, there is a 7/8 inch light gap per side. On cordless inside mounts, there is approximately 1/16 inch total light gap (31/32 inch on control end, 19/32 inch on idle end). For optimal light and glare control, outside mount is recommended.

Outside Mount:

• For an Outside Mount, blinds and shades are installed outside the window casing, covering an area larger than the window itself (some price lists and reference materials may also refer to an outside mount as OB).
• Measure the width to be covered precisely. Make sure the measurement overlaps the window opening by at least 1 1/2 inches on each side (3 inches total overlap) to ensure light control and privacy.
• Measure the height to be covered precisely, including any desired overlap (typically from top edge of the molding to the bottom edge, or to the top of sill if there is one).
• The factory makes NO allowances for an outside mount.

Vertical Blinds

Inside Mount:

• For an inside mount, blinds are installed inside a window casing or door, or wall-to-wall in a room. Each window casing must be at least 2 3/4 inches deep for a track flush mount or 3 3/4 inches deep for a louvers flush mount. If not, an angle bracket may be necessary (some price lists and reference materials may also refer to an inside mount as IB).
• Measure the inside width precisely of the window casing from one inside edge to the other edge in three different places. Keep the narrowest measurement.
• Measure the height precisely in three different places from the top edge of the opening to the bottom or the top edge of the sill, if there is one. Keep the shortest measurement.
• Do not make any deductions for clearance. The factory will take necessary deductions for a perfect fit.

Outside Mount:

• For an outside mount, blinds are installed outside of the window casing, covering an area larger than the window itself (some price lists and reference materials may also refer to an outside mount as OB).
• Measure the width of the window precisely, including the frame, if there is one. Add 3" (6" total overlap) to each side for light control and privacy.
• Measure the height of the window from the top edge of the molding to the bottom edge, or to the top of sill, if there is one. Add 3 inches for an adequate mounting area above the window.
• If the blind extends to floor (for example to cover a patio door), measure the height in three places precisely and take the smallest measurement.  Deduct at least 1/2 inch for clearance so the louvers don't touch the floor.
• The factory makes NO allowances on an outside mount.
• NOTE: If you want the entire window uncovered when the blind is fully open, you may need to add more than 6 inches to the width.
