How to Measure for Custom Curtains & Window Shades

Accurate measurements are the foundation of a better custom window-treatment fit. Use this guide before ordering LANTIME curtains, Roman shades, or sliding panel blinds.

Before you measure

  • Use a metal tape measure where possible.
  • Measure each window or opening separately, even if they look identical.
  • Write down width first, then height.
  • Check the product page for the exact mount and sizing requirements before ordering.

Custom pinch pleat curtains

  1. Measure the total area you want the two curtain panels to cover.
  2. Decide where the track or rod will sit and measure the finished drop from that point.
  3. Choose the finished width required for each panel and submit the exact finished length requested on the product page.

Inside-mount Roman shades

  1. Measure the inside width of the window opening in more than one place.
  2. Measure the inside height of the opening.
  3. Confirm that the window depth meets the minimum requirement shown on the product page.
  4. Submit the measurements requested by the product configurator; do not make your own manufacturing deduction unless the product page specifically instructs you to.

Outside-mount Roman shades

Measure the area you want covered outside the frame. For the LANTIME no-drill bamboo shades, the product guidance recommends additional overlap where space permits to improve privacy and coverage.

Sliding panel track blinds

  1. Measure the full width and height of the sliding door, large window, or opening.
  2. Decide whether the track will be wall-mounted or ceiling-mounted.
  3. Check clearances for handles, trim, and nearby furniture.
  4. Select the closest available size and submit your final dimensions carefully.

Final check before checkout

Re-measure the opening, verify width and height are entered in the correct fields, confirm inside versus outside mount, and review all custom measurements before placing the order.
