Start at 72 x 72 inches for a standard tub, then adjust to your shower and rod. AmazerBath, a shower curtain and liner maker, calls 72 x 72 the “common starting point for a typical 60-inch tub opening.” Its guide points small stalls to 36 x 72 and high rods to 72 x 84 or 72 x 96. Sizes are listed width first, then length.

The liner and curtain columns come from each maker’s own size options for one product line: AmazerBath’s Heavy Duty PEVA 8G liner, Titanker’s clear PEVA liner and fabric liner, Brooklinen’s Linen curtain, Parachute’s Organic Oasis curtain, Gorilla Grip’s waffle curtain and Lush Decor’s Nantucket curtain. A dash means none of those products comes in that size, not that the size doesn’t exist.

Where makers differ

Standard width isn’t always 72 inches. Titanker’s fabric liner comes in 70 x 72 rather than 72 x 72, and AmazerBath also sells its heavy-duty liner in 70 x 72. Behind a 72-inch-wide curtain, that liner is 2 inches narrower.

Stall widths come in steps. Between 36 and 70 inches wide, AmazerBath’s heavy-duty liner comes in 40, 48, 54 and 60 inches, and Titanker’s fabric liner in 47, 48, 54 and 60. AmazerBath’s advice for stalls is to “confirm the exact stall width before choosing a narrow size.”

Lengths go well past 84 inches. At 72 inches wide, AmazerBath’s heavy-duty liner runs from 65 to 108 inches long, including 74, 80 and 90. Titanker’s clear liner stops at 96 inches.

Extra-wide sizes are for long rod paths. AmazerBath sells a 108 x 72 liner. Its guide notes that “curved rods and extra-gathered installations may require additional width,” and says to measure the full rod path on a curved or custom rod.

How to choose the right size

AmazerBath’s guide uses two measurements:

  1. Width. Measure straight across the shower opening. For a standard tub, AmazerBath says adding about 12 inches “provides fullness so the curtain is not pulled completely taut.” Its example: a 60-inch-wide tub commonly uses a curtain around 72 inches wide.
  2. Length. Measure from the curtain rod to where you want the lower edge. In a bathtub, the liner “should hang inside the tub with enough overlap to contain water, without dragging on the tub floor.” In a walk-in shower, leave a small clearance above the floor so the curtain can dry and doesn’t pool.
  3. Curved rods. Measure the whole curve, not the straight opening, because a curve may need more curtain width.

AmazerBath adds that “many decorative fabric curtains need a separate waterproof liner.” If you’re buying both, Lush Decor’s curtain sizes (72 x 72, 72 x 78 and 72 x 84) all have a liner in the same size from both AmazerBath and Titanker.

Rod type matters too. If you haven’t picked one yet, the site’s tension rod vs mounted rod comparison covers that choice.
