🛁 Shower Curtain Size Calculator
Enter your opening width and pick a curtain type to get the right curtain and liner size, the number of rings, and the rod width — all matched to standard sizes you can buy off the shelf.
🧮 Size Your Curtain
🛁 Recommended curtain
| Curtain | 72″ W × 72″ L |

Get the drape right
A shower curtain that's too narrow gaps at the edges and lets water onto the floor; one that's too short leaves a splash zone below it. The fix is knowing two things before you buy: the size that fits your opening, and how much extra width gives a full, tailored drape rather than a flat, stretched panel.
Tell the tool your opening width, the kind of shower you have, and your ceiling height, and it returns the standard curtain and liner size to buy, the recommended width for a proper fullness, and how many rings and what rod length you'll need to finish the job.
❓ Frequently Asked Questions
What are the standard shower curtain sizes?
The most common is 72×72 inches, which fits most standard tubs and alcoves. Stall showers use a narrower 54×78, extra-long curtains are 72×84 for high ceilings or a more dramatic drape, and wide or double openings take a 108-inch-plus panel. This tool maps your chosen type straight to the nearest stock size so you can buy off the shelf.
How much wider than the opening should a curtain be?
For a gently gathered, fuller look — and so the curtain closes fully without gaps — aim for about 1.5 to 2 times the opening width. The calculator multiplies your opening by a fullness factor and rounds up to the next standard curtain width, so you know whether a 72-inch panel is enough or you need a wider one.
Should the liner be the same size as the curtain?
Yes — buy the liner in the same width and length as the decorative curtain so they hang together on the same rings. A liner that's too short lets water escape, and one that's too long pools in the tub. For a curtain you want to skim the floor, add a couple of inches of length; for a liner, keep it just above the tub lip.
How many rings or hooks do I need?
Standard curtains have grommets spaced roughly every six inches, so a 72-inch curtain takes about 12 rings and a wide 108-inch panel about 18. The calculator counts them from the curtain width. Always hang the decorative curtain and its liner on the same set of rings.
