Shower Curtain Size Chart (Inches and cm)
Most curtains come in a few set sizes. Here is a full size chart with dimensions in both inches and centimeters.
| Type | Inches (W x L) | Centimeters (W x L) | Best For |
|---|---|---|---|
| Standard | 72 x 72 | 183 x 183 cm | Most tubs and showers |
| Extra-long | 72 x 84 | 183 x 213 cm | High ceilings, tall rods |
| Stall | 54 x 78 | 137 x 198 cm | Small shower stalls |
| Extra-wide | 108 x 72 | 274 x 183 cm | Walk-in or double showers |
| Dorm | 48 x 72 | 122 x 183 cm | Tight dorm bathrooms |
| Custom | Your measurements | Your measurements | Clawfoot tubs, odd shapes |
The standard shower curtain size in cm is about 183 x 183 cm, which matches the 72 x 72 inch default. Keep this in mind if you shop from international brands that list sizes in centimeters.
How to Measure for a Shower Curtain
Measuring takes two minutes and saves you from a wrong buy. Here is the simple method.
- Measure the width. Measure the length of your rod or the opening you need to cover.
- Measure the height. Measure from where the rod sits down to a few inches off the floor.
- Add for fullness. Multiply the width by 1.5 to 2 for a nice, gathered look.
- Account for the drop. Subtract the hook drop length, usually 2 to 3 inches.
The width should always be larger than your opening so the curtain gathers instead of clinging to you. That extra width is the fullness factor, and it is what separates a flat, sad curtain from a full, hotel-style one.
To plan the rod height and placement, our curtain rods calculator helps you get it right the first time.
What Width Shower Curtain Do I Need?
Width depends on your opening plus extra for fullness. Here is a quick guide by fixture.
- Standard tub (about 60 inches wide): a 72-inch wide curtain works great
- Shower stall (36 inches): a 54-inch wide stall curtain fits well
- Walk-in shower: measure the opening and add fullness
- Double or extra-wide shower: use a 108-inch extra-wide curtain
The rule of thumb is simple. Pick a curtain wider than your opening. For a typical 60-inch tub, 72 inches of width gives the perfect amount of gather.
How Long Should a Shower Curtain Be?
Length matters as much as width. The bottom should hang close to the floor or just inside the tub.
Here is the right length for each setup:
- Inside a tub: the liner hangs inside, ending about 1 inch above the tub floor
- Standard rod height: a 72-inch length suits most setups
- High ceilings or tall rods: use an extra-long 84-inch curtain
- Walk-in shower: leave about 1 to 2 inches of floor clearance
A normal shower curtain is 72 inches long, which works for most standard rod heights. For a walk-in shower, leave that small gap at the bottom so water drains but does not pool.
Curtain vs Liner: You Need Both
Here is a tip many people miss. The decorative curtain faces out and looks nice. The liner faces in and does the waterproofing.
Together they protect your bathroom and let you pick any fabric you like for the outer curtain.
A few liner tips:
- The liner should match or slightly trail the curtain length
- Hang the liner inside the tub, the curtain outside
- Weighted magnets at the bottom keep the liner from billowing
The size of a standard shower curtain liner matches the curtain, usually 72 x 72 inches. Stall liners run smaller, around 54 x 78 inches.
PEVA vs Fabric Liner
PEVA liners are plastic, cheap, and fully waterproof. They wipe clean easily but can look a little shiny.
Fabric liners are softer, more breathable, and resist mildew well. They cost more but feel and look more premium.
For trusted care advice, the Good Housekeeping and The Spruce teams test these in real homes.
Special Setups: Clawfoot Tubs, Walk-Ins, and Kids’ Baths
Some showers need a different approach than the standard size.
Clawfoot tubs need a curved or wrap-around rod and often two curtains or one extra-wide panel. The curtain must wrap the whole tub to keep water in.
Walk-in showers need careful floor clearance. Measure the exact opening and leave a small gap at the bottom so water drains properly.
Kids’ bathrooms do best with a standard 72 x 72 inch curtain in a fun, washable, mildew-resistant fabric. Make sure the liner hangs inside the tub so the floor stays dry where little feet step out.

Pro Tips for a Better Shower Curtain
A few smart habits keep your curtain looking great and lasting longer.
- Choose a mildew-resistant material to fight mold
- Wash fabric curtains about once a month
- Use weighted magnets to stop the liner from billowing
- Pick a curved rod to add elbow room in the shower
A curved rod is a cheap upgrade that makes any shower feel bigger. To finish the look, browse our home storage organizer ideas for more bathroom touches.

What size shower curtain for a shower stall?
A stall curtain of 54 x 78 inches fits most small stalls. For a 36-inch shower, this width gives enough fullness without bunching. Always measure your stall opening first to confirm.
What size shower curtain for a standard tub?
For a standard 60-inch tub, a 72 x 72 inch curtain is ideal. The extra width gives a full, gathered look, and the 72-inch length hangs nicely just inside or over the edge of the tub.
How long is a normal shower curtain?
A normal shower curtain length is 72 inches, which suits most standard rod heights. For high ceilings or tall rods, choose an extra-long 84-inch curtain. The bottom should hang close to the floor or just inside the tub.

No. While 72 inches is the most common length, curtains also come in 78, 84, and shorter dorm sizes. Always check the dimensions on the label and measure your space before buying.

Can I get a custom shower curtain size?
Yes. If your shower is an unusual shape, many makers offer custom shower curtain sizes and lengths. Measure your width and height carefully, add fullness to the width, and order to fit. This is common for clawfoot tubs and large walk-ins.
How do I choose the right size for a kid’s bathroom?
A standard 72 x 72 inch curtain works for most kids’ tubs. Pick a fun, washable, mildew-resistant fabric, and make sure the liner hangs inside the tub to keep water off the floor where kids step out.
