Choosing the right shower curtain or liner starts with two measurements: the width of the area it needs to cover and the distance from where it hangs to the desired lower edge. Sizes are usually written as width × length. The common sizes below are useful starting points, but measuring your own shower is the best way to find a good fit.
Standard Shower Curtain and Liner Sizes
These common shower curtain sizes and fabric shower curtain liner sizes can help you narrow down your options:
| Size (width × length) | Common use |
|---|---|
| 72 × 72 in | A common starting point for a standard bathtub. |
| 36 × 72 in | A narrow shower stall; measure the opening before choosing. |
| 72 × 84 in | A taller rod position or a longer drop. |
| 72 × 96 in | An extra-long option for a high rod or tall space. |
Sizes vary by product. Use the chart as a reference, then check the exact dimensions and color-size options on the product page.

How to Measure the Width
Measure across the shower opening. If the curtain hangs from a straight rod, measure the span it needs to cover. For a curved rod, measure along the curve rather than straight across the opening.
Leave some extra width so the curtain can form folds instead of hanging fully taut. For example, a 72-inch-wide curtain over a 60-inch tub opening leaves about 12 inches of extra fabric. A curved rod or a fuller look may require more width.
How to Measure the Length
Measure from the point where the curtain will hang to the lower edge you want. If your hooks or rings lower the curtain below the rod, account for that drop. Measuring from the curtain’s attachment point can help you estimate the finished length.
- Bathtub: The liner should hang inside the tub with enough overlap to help contain water, without dragging on the tub floor. Keep the outer curtain outside the tub.
- Walk-in shower: Choose a length that provides coverage without pooling on the floor.
Choose a Size for a Tub, Stall, or Walk-In Shower
- Bathtub: 72 × 72 inches is a common starting point, but check the opening width and rod height.
- Narrow stall: A 36-inch-wide curtain may fit some stalls. Measure first, since stall openings vary.
- Walk-in shower: Measure the opening and the distance from the hanging point to the lower edge. On a curved track, measure along the curve.
- High rod: Consider an extra-long size such as 72 × 84 or 72 × 96 inches, based on your measurements.

Common Sizing Mistakes
- Choosing by ceiling height instead of measuring from the rod.
- Forgetting that hooks or rings can lower the finished curtain.
- Matching the curtain width exactly to the opening, leaving no room for folds.
- Letting the curtain or liner drag or pool on the floor.
- Assuming every color comes in every size.
Frequently Asked Questions
What does 72 × 72 mean?
It means the curtain is 72 inches wide and 72 inches long.
How do I choose between 72 × 84 and 72 × 96?
Measure from the hanging point to the desired lower edge. Choose the length that provides coverage without dragging; don’t rely on ceiling height alone.
Do the outer curtain and liner need to be the same length?
No. The liner should hang inside the tub when used with a bathtub, while the outer curtain stays outside. Choose lengths that cover the shower area without dragging.
Measuring before you shop helps avoid a curtain that is too narrow, too short, or difficult to dry.
