Curtain Size Chart: Standard Lengths and Widths

Every standard ready-made curtain length and width in inches and centimeters, which length suits which room, and the curtain width and panel count for common window sizes.

Updated October 8, 2026

Ready-made curtains come in a handful of standard lengths and panel widths. Choosing the right size comes down to two measurements: where your rod is (for length) and how long the rod is (for width).

Standard curtain lengths

Length	In cm	Typical use
63 in	160 cm	Sill or apron length; kitchens, bathrooms, small windows
84 in	213 cm	Floor length with the rod just above a standard window (8 ft ceilings)
95 in	241 cm	Floor length with the rod hung higher, or near an 8 ft ceiling
96 in	244 cm	Same as 95 in; brands use one or the other
108 in	274 cm	Floor length for 9 ft ceilings, or a rod near a 9 ft ceiling
120 in	305 cm	10 ft ceilings, two-story rooms, tall windows

Curtain length is measured from the rod to the hem. To pick one, measure from your rod to ½ inch above the floor and choose the nearest standard length, then raise or lower the rod slightly to match. The guide to how high to hang curtains shows the rod heights for 8, 9 and 10 ft ceilings.

Standard curtain widths

Panel width	In cm	Notes
38–42 in	97–107 cm	Narrow panels, often sheers or tab tops
50 in	127 cm	The most common single panel
52–54 in	132–137 cm	Common for grommet and blackout panels
100 in and up	254 cm and up	Extra-wide panels or pairs sold as one

Widths are measured flat. For a full look, all your panels together should be about 2 times the rod length (1.5× for a flat look, 2.5–3× for pleats and sheers).

Curtain sizes for common windows

With the rod extending 10 inches past each side and 2× fullness:

Window width	Rod	Total curtain width	50 in panels	54 in panels
36 in	56 in	112 in	4	4
48 in	68 in	136 in	4	4
60 in	80 in	160 in	4	4
72 in	92 in	184 in	4	4
96 in	116 in	232 in	6	6

Panel counts are rounded up to an even number so each side gets the same. If the count looks high, one pair of extra-wide panels does the same job.

Metric curtain sizes

Outside the US, curtains are usually sold in centimeters, and sizes vary by country and store. In the UK, for example, common ready-made drops (lengths) are 137, 183 and 229 cm (54, 72 and 90 in), with widths from about 117 to 229 cm. Always check the store’s own size chart. To convert any size, use inches to cm or cm to inches.

Find your exact size

Every window is different. The curtain size calculator works out the length, width, panel count and rod size from your own measurements, and how to measure for curtains shows how to take them. Updating the walls too? The board and batten calculator helps plan an accent wall around the window.

Frequently asked questions

What are the standard curtain lengths?

In the US, ready-made curtains come in 63, 84, 95, 96, 108 and 120 inch lengths (160, 213, 241, 244, 274 and 305 cm). 84 and 95/96 inches are the most common, because they fit floor-length curtains in rooms with 8-foot ceilings.

What is the standard width of a curtain panel?

Most single panels are 50 to 54 inches wide, measured flat. Some brands sell 38–42 inch panels and extra-wide panels of 100 inches or more. Always check the package, and add up the panels to get the total width.

What size curtains for a 60 inch window?

A 76–84 inch rod (the window plus 8–12 inches each side) and about 160 inches of curtain width at 2× fullness: four 50-inch panels or three 54-inch panels rounded up to four. For floor length in a room with 8-foot ceilings, 84-inch curtains.

Are 84 or 96 inch curtains better?

It depends on the rod height. 84-inch curtains reach the floor when the rod is about 84½ inches up, just above a standard window. 96-inch curtains need the rod about 96½ inches up, so they suit 9-foot ceilings or a rod hung near an 8-foot ceiling.
