Bedding Sizes Chart: Complete Dimensions & Deep Pocket Guide

Hotel mattresses are thicker than most home mattresses. Typically 14-16 inches with built-in pillow tops. Standard fitted sheets fit mattresses up to 14 inches. If your mattress is thicker (or you use a topper), you need deep pocket sheets. This guide covers every bedding size, pocket depth, and hotel-specific dimension you need before buying.

What Are Standard Bedding Dimensions?

US bedding sizes range from Twin (38 x 75 inches) to California King (72 x 84 inches), with each size requiring matching flat sheets, fitted sheets, comforters, and pillows in specific dimensions. The measurements below reflect current US bedding industry standards and match the sizes you will find on Amazon, Brooklinen, and at Macy’s.

Find Your Exact Sheet Size

The table above covers standard dimensions. But your actual sheet needs depend on your specific mattress depth and whether you use a topper. Enter your mattress details below and we’ll tell you exactly what pocket depth and sheet size to buy.

What Is Deep Pocket? (And When Do You Need It?)

Deep pocket fitted sheets fit mattresses 14-18 inches deep. Standard fitted sheets fit 7-14 inches. If your mattress plus any topper exceeds 14 inches total height, standard sheets will pop off the corners during the night. Most hotel mattresses are 14-16 inches, which is why hotel sheets are almost always deep pocket.

How to measure: Remove all bedding. Measure from the bottom seam of the mattress to the highest point of the top surface. Include any topper or mattress pad. Then add 2-4 inches of allowance. Fitted sheets need slack to tuck securely under the mattress corners.

The most common mistake: buying standard pocket sheets for a mattress with a topper. A 12” mattress plus a 3” memory foam topper equals 15” total. Standard sheets won’t hold. You need deep pocket.

How Do Hotel Collection Sizes Compare to Standard Home Bedding?

Hotel Collection bedding from Macy’s uses slightly different dimensions than standard retail bedding. Their King flat sheet measures 110 x 96”, wider than the standard 108 x 102”. This matters if you’re buying Hotel Collection pieces to mix with other brands.

Hotel Collection sheets are designed for hotel-style thick mattresses. The 18” deep pocket fits mattresses up to roughly 16” with a topper. They work perfectly on standard mattresses too. You’ll just have slightly more tuck-in room, which actually keeps fitted sheets more secure throughout the night.

King vs California King: Which Do You Have?

King (also called Eastern King) is 76 x 80 inches. Wide but shorter. California King is 72 x 84 inches. Narrower but longer. They are NOT the same size. Using King sheets on a Cal King bed means the fitted sheet is 4 inches too wide and 4 inches too short. It won’t fit properly.

If you’re unsure which you have, measure the mattress. Width tells you everything. 76 inches wide = King. 72 inches wide = Cal King. Check before ordering.

Cal King bedding is harder to find and sometimes costs 5-10% more due to lower production volume. Online retailers (Amazon, Brooklinen) typically stock both, but in-store options for Cal King can be limited.

What Size Pillow Do I Need?

Pillow size should match your bed size for both function and presentation. Standard pillows (20 x 26 inches) fit Twin and Full beds. Queen pillows (20 x 30 inches) fit Queen beds. King pillows (20 x 36 inches) fill the full width of King and California King beds. Euro pillows (26 x 26 inches) are decorative squares used as backing in the hotel pillow stack.

Hotels use King pillows on King beds. Two 36-inch pillows across a 76-inch bed leaves only 4 inches of headboard showing, creating a full, luxurious look. Put Standard pillows on a King bed and you get a 24-inch gap that looks incomplete.

For the most hotel-like presentation: use two King sleeping pillows at the back, two Euro shams in front, and two decorative pillows or a bolster at the very front. Remove all decorative pillows before sleeping. Hotels do this every day during turndown service.

Frequently Asked Questions

Why don’t my fitted sheets stay on?

Two reasons: wrong pocket depth (your mattress is deeper than the sheet’s pocket) or worn elastic. Measure your mattress plus topper total height. If it’s over 14 inches, you need deep pocket sheets. If it’s over 18 inches, you need extra deep pocket. Also check if your elastic has lost tension after 50+ washes. Sheet suspenders ($8-$12) are a cheap fix for elastic that’s giving up.

Can I use Queen sheets on a Full bed?

Technically yes. Queen sheets are 7 inches wider and 5 inches longer than Full. The fitted sheet will be slightly loose but usable. The flat sheet will hang lower on the sides. Not ideal for a crisp hotel look, but functional in a pinch.

What size duvet cover do I need for my comforter?

Match the duvet cover to the comforter insert size, NOT the bed size. A Queen comforter (typically 86-88 x 86-92 inches) needs a Queen duvet cover. Mismatched sizes cause bunching and shifting inside the cover. If in doubt, measure your actual comforter with a tape measure before ordering.
