Bed Skirt Sizes Chart | Fit Any Mattress Correctly

Standard US bed skirt sizes match platform dimensions, led by Twin 39″ x 75″, Full 54″ x 75″, Queen 60″ x 80″, King 76″ x 80″, and California King 72″ x 84″.

Buying a bed skirt without checking the size chart is a gamble. Pick the wrong platform width or drop length, and you get a skirt that floats above the floor, drags beneath it, or leaves your box spring exposed on the sides. The fix is knowing how mattress sizing maps to skirt sizing, and that starts with the one fact most guides skip.

Here’s the catch. A bed skirt is sized by the platform it covers—the box spring or the space below your mattress—not always by the mattress name. But King sizes vary by brand, and drop lengths are anything but universal. Checking the actual chart before you order is the only way to get a clean fit.

Bed Skirt Sizes Chart: US Standards And Variations

This table shows the common US bed skirt dimensions by mattress size, with the caveat that not every brand lists identical numbers. Always confirm the specific chart from the manufacturer or retailer before buying.

For specialty frames, the company also stocks Super Queen, Super King, and Cal King variants that go beyond the basic chart.

Drop Length: The Measurement Everyone Forgets

The drop is the distance the skirt falls from the top of the box spring to the floor. Common ready-made drop lengths are 14″, 15″, 16″, 18″, and sometimes 21″ for taller bed frames. Get this wrong and the whole skirt looks off.

Different manufacturers set their own “standard” drops. Eastern Accents and Fabtex use 14″ drops in their product examples, while Southshore Fine Linens lists 15″ across sizes, and HiEnd Accents bumps to 16″ for Twin and Full, and 18″ for Queen and King. MattressNut states the range plainly, noting bed skirt heights run from 14 to 18 inches.

If the drop is too short, the skirt floats. Too long, and it drags or bunches.

How To Measure Your Bed For The Right Skirt Size

Measure the platform, not the mattress top. Follow these steps and you will get a fit that looks tailored.

1. Measure the width across the box spring or bed frame from left to right.
2. Measure the length from the head to the foot of the platform.
3. Measure the drop from the top of the platform straight down to the floor.
4. Match your numbers to a skirt chart, rounding up to the nearest standard size if you fall between options.

The Company Store notes that a bed skirt serves both a decorative and a functional purpose, covering the space below the mattress and hiding whatever sits under the bed. A roundup of bed skirts with split corners can help if your frame has posts or legs that need to fit through the skirt’s openings.

A slightly wide skirt tucks under the mattress; one that’s too narrow leaves gaps at the corners and looks sloppy.

Common Sizing Pitfalls Worth Avoiding

• Mattress name vs. platform size. Most charts label the skirt by the mattress it fits, not the exact finished fabric dimensions. Check the actual inch measurements, not just the label.
• King isn’t universal. Some charts use 76″ x 80″, others 78″ x 80″. A two-inch difference across a wide bed means visible sagging or stretching.
• Twin XL and California King get overlooked. Twin XL runs 39″ x 80″ and Cal King is a full 84″ long. Buying a standard Twin or King skirt for either creates an obvious mismatch.

Eastern Accents publishes a bedding measurement guide PDF that spells out its exact sizing, and Fabtex’s bed skirt brochure offers both dimension examples and yardage requirements. Those official charts beat any secondhand source.
