Organic Cotton Shower Curtain Sizing: Tub, Stall, and Extra Long

Quick answer

For a standard tub, choose a curtain at least 70 inches wide and 72 inches long. For a stall shower, a 54-inch-wide curtain is usually enough. If your rod sits above 75 inches or you have a clawfoot tub, look for an extra long curtain around 84 to 96 inches. Measure your rod and tub first, then match the curtain to those numbers.

A shower curtain that's too short leaves water on the floor. One that's too wide bunches up and blocks light. The fix is simple: measure your rod and tub before you shop. This guide covers the standard sizes for tubs, stalls, and extra long drops, plus how to measure for a curtain that actually fits.

You'll also see how fabric choice affects fit. Cotton and hemp curtains behave differently from plastic liners, and that changes what size you need. We'll walk through the numbers, the trade-offs, and a few decision rules so you can order once and get it right.

How to measure for a shower curtain

Start with a tape measure and a helper if you have one. Measure the rod from end to end, not the tub. That's your width. For length, measure from the rod down to where you want the hem to end. For a tub, the hem should fall 1 to 2 inches above the floor or just inside the tub lip. For a stall, it should stop at or slightly below the threshold.

Write both numbers down before you open a browser. Most sizing mistakes happen because people guess from memory. If you're replacing a curtain, measure the old one too. That tells you whether the previous size worked or whether you've been fighting a bad fit for years.

• Measure rod width, not tub width.
• For length, measure from the rod to the desired hem.
• Add 2–4 inches of width for gentle folds if your rod allows.
• Check that the hem clears the floor by 1–2 inches.

Standard tub shower curtain dimensions

Most tub showers use a curtain that's 70 to 72 inches wide and 72 inches long. That width gives you enough fabric to close the curtain without stretching it tight. The 72-inch length works with a rod mounted at the typical 72 to 75 inches above the floor. If your rod is higher, the curtain will float above the tub and water will escape.

Width matters more than most people think. A 70-inch curtain on a 60-inch rod gives you about 10 inches of extra fabric, which creates soft folds and helps the curtain hang straight. If you have a curved rod, measure the arc, not the straight-line distance. Curved rods need more width.

• Standard tub: 70–72 inches wide, 72 inches long.
• Curved rods: measure the full arc for width.
• Rod height above 75 inches? Consider extra long.

Stall shower curtain size

Stall showers are narrower, so a standard tub curtain will overwhelm them. The typical stall shower curtain size is 54 inches wide and 78 inches long. Some stalls use 48-inch widths, and a few use 60. The length is often longer than a tub curtain because stall rods tend to sit higher and the curtain needs to reach the threshold.

Measure your stall rod before assuming. A 54-inch curtain on a 48-inch rod gives you enough overlap to close fully. On a 60-inch rod, a 54-inch curtain will gap. If your stall has a door instead of a rod, you may not need a curtain at all, but if you do, check the track width and the drop to the sill.

• Common stall size: 54 inches wide, 78 inches long.
• Check whether your stall uses a rod or a track.
• A 54-inch curtain on a 60-inch rod will gap.

Extra long shower curtain: when you need one

You need an extra long shower curtain when your rod is mounted high, when you have a clawfoot tub, or when you want the curtain to puddle slightly for a spa look. Extra long usually means 84 to 96 inches in length. Width stays in the 70 to 72 inch range for tubs, though some extra long styles come wider.

Clawfoot tubs are the classic case. The tub sits away from the wall, so the rod is often higher and the curtain needs to drop further. A 72-inch curtain on a high rod leaves a gap at the bottom. Measure from the rod to the floor, then subtract 1 to 2 inches. That's your target length.

• Extra long = 84–96 inches in length.
• Clawfoot tubs and high rods are the main use cases.
• Subtract 1–2 inches from rod-to-floor for hem clearance.

How fabric affects sizing

Cotton and hemp curtains are woven tightly enough to work without a plastic liner. That's a real advantage, but it changes how the curtain hangs. Natural fibers have more body than thin plastic, so they hold their shape and don't cling. They also dry more slowly, which means you want a hem that clears the floor to avoid wicking.

If you're switching from a plastic liner plus decorative curtain to a single cotton or hemp curtain, you may need a different size. The old setup often used a liner that was shorter than the decorative curtain. A single-layer curtain needs to cover the full opening on its own. Measure for the single layer, not the old two-layer system.

• Natural fibers hang with more body than plastic.
• Keep the hem off the floor to prevent wicking.
• Measure for a single layer, not your old liner setup.

Rings, rod, and hem clearance

Shower rings add about 1 to 2 inches to the top of the curtain. If you're calculating length, include the ring height. Rust-proof rings are worth the small upgrade if your bathroom stays humid. They also slide more smoothly, which matters when you're opening and closing a heavier cotton curtain.

Hem clearance is the last check. For a tub, aim for 1 to 2 inches above the floor or just inside the tub lip. For a stall, the hem should sit at or slightly below the threshold. If you're between sizes, go longer rather than shorter. You can always hem a curtain, but you can't add fabric.

• Include ring height in your length calculation.
• Rust-proof rings help in humid bathrooms.
• Between sizes? Choose longer and hem if needed.

Decision rules for sizing your curtain

• If your rod is 60 inches or less and the drop is 72–75 inches: Choose a standard tub curtain, 70–72 inches wide and 72 inches long. This covers the most common tub setup. Standard tub size is the default for a reason.
• If your rod is 48–54 inches and the drop is 78 inches or more: Choose a stall shower curtain, typically 54 inches wide and 78 inches long. Check the rod width first; a 54-inch curtain gaps on a 60-inch rod. Stall showers need narrower curtains, not shorter ones.
• If your rod is above 75 inches or you have a clawfoot tub: Choose an extra long curtain, 84–96 inches long. Measure from rod to floor and subtract 1–2 inches for hem clearance. Extra long prevents the floating-curtain gap.
• If you're switching from a liner plus decorative curtain: Measure for a single layer. Your old liner was likely shorter than the decorative curtain, so the combined size won't match a single cotton or hemp curtain. Single-layer curtains need to cover the full opening.
• If you're between two lengths: Choose the longer one. You can hem a curtain, but you can't add fabric. Keep the hem 1–2 inches off the floor to avoid wicking. Longer is safer; hemming is easy.

Measure your rod width and rod-to-hem drop before you order. Standard tub, stall, and extra long sizes cover most bathrooms, and the decision rules above will point you to the right one. If you're between sizes, go longer and hem. A well-fitted organic cotton or hemp curtain hangs better, dries faster, and keeps water where it belongs.
