What You Will Need

Helpful Hints Before You Begin Measuring for Roman Shades:

  • For the most accurate measurements, only use a steel tape measure.
  • Don’t mix up width and height measurements. Always follow the width by height format (W x H) and mark them as such.
  • Measure to the nearest 1/8 inch. Never round up or down to the nearest half or whole inch.
  • If you’re measuring for more than one window, measure each one individually – never assume that your windows are the same size, even if they may look alike.

How to Measure for Inside Mount Roman Shades

Inside mount Roman shades are installed inside the window frame or casing – they provide a sleek, clean look which can showcase your window size and moldings. If you’re interested in measuring for inside mount Roman shades, follow these steps:

  1. Measure the depth of your window frame, from the front of the opening to the glass. You’ll need this measurement to ensure your window recess meets the minimum depth requirement for an inside mount. Refer to the Mounting Requirements section for the Roman shade you’ve chosen to ensure your window meets the requirement for an inside mount.
  2. Measure the width of each window. Record the width at the top, middle, and bottom of your window opening. Circle the narrowest measurement of the three – this is the number you submit for your window’s width.
  3. Measure the height of your window opening in three places: left, center, and right. Circle the tallest measurement - this is the number you submit for your window’s height.
  4. Order at the exact opening size with no deductions. The factory will take deductions in production.
  5. Double check that your measurements follow the width by height format (W x H).

How to Measure for Outside Mount Roman Shades

Outside mount Roman shades are mounted on the window molding or wall above your window. Outside mount shades are a good choice if an inside mount is not possible due to window depth or obstructions around the window frame. Follow these simple steps to measure your windows for outside mount Roman shades:

  1. Check the mounting requirements on your Roman shades to ensure you have enough flat surface for mounting hardware.
  2. Determine the width of the Roman shades you want to order. If you have window trim, simply measure to the far edges of the trim from left to right.
  3. If your window has no trim, we recommend adding two to three inches on each side of your window to provide light gap coverage and privacy. Mark these additions on each side and measure the width between them in a straight line.
  4. Determine the height of the shades you will order. If you have a protruding window sill, start at the sill and measure three inches beyond the top of the window opening to accommodate for mounting hardware.
  5. If you do not have a protruding window sill, we recommend starting your measurement two inches below the sill for maximum coverage and then measure three inches beyond the top of the window opening to accommodate for mounting hardware.
  6. Double check that your measurements follow the width by height format (W x H). Remember, with outside Roman shades, your product will be made to the exact specified size.
