How to Measure for Custom Curtains and Blinds

How to Measure Custom Curtains

When measuring custom curtains, start with the full width of the curtain track, curtain rod, or planned installation area. Curtains are usually not measured only by the glass width, because they often need extra side coverage for privacy, light control, and a softer finished look.

Next, measure the curtain drop from the track, rod, or installation point down to where you want the curtain to finish. Some customers prefer curtains to finish just above the floor, while others prefer a softer look where the curtains gently touch the floor.

For curtains, it is usually helpful to check the track width, planned curtain drop, heading style, fullness, and whether the curtains should extend beyond the window frame.

How to Measure Custom Blinds

Blinds are measured differently from curtains. Before measuring, you need to decide whether the blind will be installed inside the window frame or outside the window frame. This choice affects the final width, height, coverage, and appearance.

For inside mount blinds, measure the inside width and height of the window recess carefully. This option creates a neat, built-in look, but it requires more accurate measurements.

For outside mount blinds, measure the full area you want the blind to cover. This option can provide better privacy and stronger light blocking, especially when the window frame is shallow or when more coverage is needed.

If you are measuring for Roman blinds, you can also follow our Roman blind measuring guide for a more product-specific reference.

Key Differences Between Measuring Curtains and Blinds

The main difference is that curtains are usually measured from the track, rod, or wider installation area, while blinds are measured based on the window recess, frame, or exact coverage area.

Curtains usually need extra width for fullness and drape. Blinds need more precise sizing for fit, operation, and installation. This is why it is important to understand how to measure for custom curtains and blinds before placing an order.
