A 75-inch long shower curtain isn’t a standard retail size, so you’ll need to measure your rod height correctly and either buy an 84-inch curtain to hem or go custom for that exact drop.
You measured the gap and came up with 75 inches. That’s the problem — 72 and 84 are the only standard lengths mass-produced for US bathrooms. A 75-inch finished curtain exists, but only by choosing the right starting size and doing the math on ring drop, rod height, and hem allowance. The table below covers which standard curtain gets you there depending on your rod placement.
Which Standard Length Gets You a 75-Inch Drop?
The answer depends entirely on where you install the rod, not on the curtain you buy. Standard 72-inch curtains hang about 8–10 inches below the rod (via the rings), so they work best when the rod sits 80–82 inches from the floor. For a true 75-inch panel, you need an 84-inch curtain and a rod placed at 83–85 inches from the floor, because the rings subtract 8–10 inches from the fabric length. A 72-inch curtain hung at that same height would leave a 10–13 inch gap above the floor, which looks unfinished and lets water escape.
| Your Rod Height (Floor to Top of Rod) | Recommended Curtain Length | Final Drop After Rings (8-10″ subtracted) |
|---|---|---|
| 80-82 inches | 72 inches | 72 inches |
| 83-85 inches | 84 inches, hemmed by ~9 inches | 75 inches |
| 86 inches or higher | 84 inches (unhemmed) | 76 inches (no hem needed) |
How to Measure Your Shower for an Accurate Fit
Measuring is the only way to know which route works. Start with width: measure wall-to-wall where the rod will sit, then add 12 inches for a relaxed gather — a 72-inch rod on a 60-inch opening looks full and doesn’t gap. For height, measure from the top of the rod (where the rings hook) straight down to the floor. Subtract 8 to 10 inches for the ring and buttonhole drop. The result is the curtain length you need. If that number is 75 inches, you can either hem an 84-inch panel or order a custom 75-inch curtain from a specialty retailer.
Common Mistakes That Throw Off the Measurement
The most frequent error is forgetting to subtract the ring drop — a rod at 83 inches does not mean a 75-inch curtain fits unless the rings are factored in. Other mistakes include measuring along a diagonal (always plumb vertical), buying a liner larger than the curtain (it should match or be 1–2 inches smaller), and trying to add length to a 72-inch curtain by extending the rod downward, which leaves the panel too wide at the bottom. Also verify that the curtain has at least 12 buttonholes for a 72-inch panel or 15 for an 84-inch panel — fewer holes can sag between hooks and let water through the gap.
For readers ready to buy, the best part is that once you know your exact rod height and drop, our top picks for 75-inch long shower curtains cover the custom and hem-friendly options that actually fit the measurement.
Fitting the Curtain Into Your Tub Correctly
The right length is useless if the curtain hangs outside the tub. The fabric must sit inside the tub edge, overlapping the rim by 6 to 12 inches. For the bottom clearance, leave 1–2 inches above the floor to prevent mold and mildew from wicking up the fabric. If the tub has a lip, the curtain should extend at least 5 inches below the rim to trap water inside. A liner that is 1–2 inches shorter than the outer curtain works best — it keeps water contained without bunching at the bottom.
FAQs
Can I just buy a 72-inch curtain and hang it higher?
Yes, if your rod is 80–82 inches from the floor, a 72-inch curtain with standard rings will end roughly at the tub rim. It won’t give you a 75-inch drop, but it will function correctly as long as it overlaps the tub by 6–12 inches.
Do I need a custom curtain for a 75-inch measurement?
Only if you want the exact finished length of 75 inches without hemming. Most people buy an 84-inch standard curtain and hem it down by 9 inches, which is cheaper and widely available. Custom curtains start at specialty retailers.
What’s the right rod height for a 75-inch curtain drop?
Install the rod at 83–85 inches from the floor. After the rings subtract 8–10 inches, the curtain will drop to roughly 75 inches. This leaves a 1–2 inch gap above the floor for mold prevention.
