This tool finds the curtain length for 8 foot ceilings. It starts at an 8 ft (96 in) ceiling and works out the floor-length curtain for your ceiling height and rod position, then names the closest ready-made length from 63, 84, 96, 108 and 120 in. It runs in your browser, is free, and needs no sign-up. You can type heights in in, ft, cm or m, and nothing you enter is uploaded.
The results are calculated from your inputs. They show the length your rod position needs next to the lengths that common guides list, so you can compare them. They do not tell you which length is correct for your room.

How to use the Curtain Length for 8 Foot Ceilings
- Open the page. The ceiling height starts at 96 in (8 ft), so you can skip this step if your ceiling is 8 ft.
- If your ceiling is a different height, type it in. You can enter the value in in, ft, cm or m.
- Choose a rod position. The “rod near the ceiling” preset places the rod a set distance below the ceiling, starting at 3 in. The “rod above the frame” preset measures from the floor to the top of the window frame, starting at 80 in, and adds the rod’s distance above the frame, starting at 4 in.
- Change the distance values to match your plan. The tool will show an error if the rod would be at or above the ceiling.
- Open “More options” to choose a hem. “Floor length” stops 1/2 in above the floor, “trouser break” adds 2 in on the floor, and “puddle” adds 3 in. You can also type in an offset.
- Read the result. “Length needed” is your rod height minus the gap above the floor, plus any extra for the hem you chose.
- Check the closest ready-made length and the next length up and down, with the difference in inches. Compare these with the guide table, which shows each guide’s own length for your ceiling height.
With the default settings, the length needed is 92.5 in. The closest ready-made length is 96 in, which is 3.5 in longer, and 84 in is 8.5 in shorter.
How is curtain length calculated for 8 foot ceilings?
The tool works out a length from where the rod sits. It takes the rod height and subtracts the gap you leave above the floor. For an 8 foot ceiling with the default rod 3 in below the ceiling, the rod is at 93 in, and the length needed is 92.5 in with a 1/2 in gap.
Why does rod height change the curtain length?
The rod height is the starting point for every result. If the rod is near the ceiling, the rod height is the ceiling height minus the distance below the ceiling. If the rod is above the frame, it is the frame top plus the distance above the frame. A higher rod needs a longer curtain, so the length needed rises with it.
What do the rod position guides say for 8 foot ceilings?
The guides do not agree. Guide B says to place the rod as close to the ceiling as possible, or at least 3 in above the window, with at least 1 in under the ceiling. Guide D says 4 to 6 in above the frame, and guide G says 4 to 8 in above the trim. Guide A says about a foot above the window in taller homes and nearly to the ceiling with 8 ft ceilings. The page shows how far above the window each guide puts the rod, from 3 to 12 in.
Why do guides list different lengths for an 8 foot ceiling?
Guide A lists 96 in for an 8 ft ceiling, where the curtain rests on the floor. Guides B and D list 84 in. These are standard lengths for a room, not lengths worked out from a rod height, so they can differ from the length the tool calculates. That is why the table sits next to the calculated result.
Why does the tool name the closest ready-made length?
Ready-made curtains come in set lengths, so the calculated length rarely matches one exactly. The tool compares your length needed with 63, 84, 96, 108 and 120 in. It shows the closest one and the next lengths up and down, with the difference in inches. A ready-made length longer than the length needed is not the same as your calculated length: the difference shows in inches, so you can see how far the hem would land from the one you chose.
What do the warnings mean?
A warning appears when a value falls outside the range the tool expects. The rod height should be between 36 and 156 in, the ceiling between 84 and 180 in, and the length between 63 and 120 in. A warning does not mean your curtain is wrong. It means you should check that the number you typed is correct.

Frequently asked questions
What curtain length do I need for an 8 foot ceiling?
With the default rod 3 in below the ceiling and a 1/2 in floor gap, the length needed is 92.5 in. The closest ready-made length is 96 in. Guide A lists 96 in for this ceiling, while guides B and D list 84 in.
Is 84 or 96 inches the right curtain length for an 8 foot ceiling?
The tool does not say one is correct. The guides list both, so the better choice depends on your rod position and the hem you want. Compare the length needed from the tool with the guide table to see which sizes are closest.
What is a puddle hem?
A puddle hem adds 3 in of extra length on the floor. You choose it under “More options”, next to “floor length” and “trouser break”, which adds 2 in.
Can I use this tool for a 9 foot ceiling?
Yes. Change the ceiling height from 96 in to the height you need. The page for 9 foot ceilings lists the guide sizes for that height.
Why does the tool show an error for my rod position?
An error appears when the rod would be at or above the ceiling. Reduce the distance above the frame, or increase the distance below the ceiling, so that the rod sits under the ceiling.
Does the tool check my curtain length against a building code?
No. The tool calculates a length from your inputs and shows lengths from named guides. It does not check whether a result meets any code or standard.
