Choosing the right shower curtain size is just as important as selecting the right style. A curtain that's too short can leave water on your bathroom floor, while one that's too narrow may not fully cover the shower opening.
Whether you're replacing an old shower curtain or shopping for a new bathroom, understanding standard shower curtain dimensions will help you find the perfect fit.
In this guide, we'll explain the most common shower curtain sizes, how to measure your shower, and how to choose the right polyester shower curtain for your bathroom.
What Is the Standard Shower Curtain Size?
The most common standard shower curtain size is:
72 × 72 inches (183 × 183 cm)
This size fits most standard bathtubs and combination tub-and-shower units found in homes across North America.
If you're unsure which size to buy, a 72 × 72-inch shower curtain is usually the safest choice for a standard bathroom.
Common Shower Curtain Sizes
Although 72 × 72 inches is the industry standard, shower curtains are available in several sizes to fit different bathroom layouts.
| Shower Curtain Size | Best For |
|---|---|
| 72 × 72 in | Standard bathtub and shower combo |
| 70 × 72 in | Some standard shower spaces |
| 72 × 84 in | Bathrooms with higher ceilings |
| 72 × 96 in | Extra-tall showers |
| 108 × 72 in | Double shower or clawfoot tub |
Choosing the correct size helps improve water containment while creating a cleaner, more balanced appearance.
How to Measure Your Shower
Before purchasing a new shower curtain, take a few simple measurements.
Measure the Width
Measure the full width of your shower or bathtub from wall to wall.
Your shower curtain should be slightly wider than the opening so it can create soft folds when closed.
A good rule of thumb is to choose a curtain that's 8–12 inches wider than the shower opening.
Measure the Height
Measure from the shower curtain rod to the floor or bathtub rim.
The bottom of the curtain should hang:
- Just inside the bathtub for tub-and-shower combinations
- About 1–2 inches above the bathroom floor for walk-in showers
This helps prevent water from escaping while avoiding unnecessary contact with the floor.
How High Should a Shower Curtain Be Hung?
For most bathrooms, the curtain rod is installed about 75–77 inches above the floor.
With a standard 72-inch shower curtain, this creates enough clearance to keep the curtain inside the tub while maintaining a neat appearance.
If your ceilings are higher than average, you may prefer an extra-long shower curtain instead.
When Do You Need an Extra-Long Shower Curtain?
An extra-long shower curtain is useful when:
- Your shower curtain rod is mounted higher than normal
- Your bathroom has high ceilings
- You have a walk-in shower
- You want a more luxurious, floor-length look
Using a curtain that's too short can leave gaps where water may escape, so choosing the appropriate length is important for both function and appearance.
What Width Should Your Shower Curtain Be?
Many shoppers focus only on length, but width is equally important.
Your shower curtain should never be exactly the same width as your shower opening.
Instead, choose one that's slightly wider to allow the curtain to drape naturally. This not only looks better but also helps reduce water splashing outside the shower.
Does Curtain Material Affect the Size?
The recommended size remains the same regardless of material.
Polyester shower curtains are especially popular because they:
- Drape naturally
- Dry quickly
- Resist wrinkles
- Are easy to machine wash
- Work well with or without a shower curtain liner
Selecting the correct size ensures these benefits are fully realized.
Frequently Asked Questions
What is the standard shower curtain size?
The standard shower curtain size is 72 × 72 inches, which fits most bathtubs and shower-tub combinations.
What is the standard length of a shower curtain?
The standard length is 72 inches, although longer options are available for taller showers.

No. A shower curtain should hang just above the floor or inside the bathtub to prevent water leaks and reduce the chance of mold developing.
How wide should a shower curtain be?
