Curtain Length Made Easy: Measure, Choose, and Hang Like a Pro

Staring at a window and wondering why your curtains look too short or drag on the floor? The culprit is almost always the length. Getting the right drop doesn’t have to be a guessing game. In this guide you’ll see exactly how to measure, what the common lengths are, and when to break the rules.

Step‑by‑Step: How to Measure for the Perfect Drop

Grab a tape measure and follow these three quick steps. First, decide where the rod will sit – inside the window frame, on a console board, or mounted outside the frame. Your rod position changes the starting point.

Second, measure from the rod (or the top of the rod) down to the floor. If you want the curtains to kiss the carpet, stop at the floor line; for a polished look, pull the fabric up about an inch. Third, add extra length for hems. Most curtains need a 2‑4 inch hem, so add that to your measurement before cutting.

Pro tip: If you have a high ceiling, consider a “puddle” length. Add 2‑6 inches for a soft pool on the floor, but keep it tidy – too much puddling gathers dust.

Standard Curtain Lengths and When to Use Them

Most retailers list curtains in four basic drops: 84 in (short), 96 in (standard), 108 in (long), and 120 in (extra long). Here’s when each works best:

• 84 in (7 ft): Ideal for low windows, kitchen backsplashes, or sliding doors that sit close to the floor.
• 96 in (8 ft): The go‑to length for most living rooms. It offers a clean break just above the floor.
• 108 in (9 ft): Perfect for tall ceilings or when you want a dramatic look without a full puddle.
• 120 in (10 ft): Use this for vaulted ceilings or when you love the romantic pool effect.

If your window doesn’t match these presets, most fabric stores will cut custom lengths for a small fee. It’s worth it for a perfect fit.

Another factor is the rod width. A wider rod pushes the curtains out, making the window appear larger. If you use a wide rod, you might want a slightly longer drop to keep the fabric from looking cramped.

Finally, remember the style of your curtains. Grommet tops sit close to the rod, so you may need a little extra length compared to tab tops, which sit lower.

With the right measurements and an eye on standard drops, you’ll never have a curtain that looks off again. Measure twice, cut once, and enjoy a window that feels pulled together.
