The smallest bed size is the twin, designed to comfortably hold one sleeper. Twin bedding fits snuggly onto a 38 inch wide and 75 inch long mattress. Depending on the bedding material and brand, the dimensions of the flat sheet and duvet may vary. As long as these sheets are longer and wider than the dimensions of the mattress, you shouldn’t have any issues.

Many apartment dwellers choose a full size mattress (also called a double) because it’s big enough to sleep comfortably, but doesn’t take up the whole room.

Don’t know the difference between a fitted sheet and a flat one? Here’s a quick guide on the types of sheets you’ll encounter when shopping for bedding.
A fitted sheet is designed to fit perfectly onto your mattress. It typically has elastic in the corners to help the sheet grip onto the mattress.
Fitted sheets need to be specifically sized to complement the mattress dimensions. If the fitted sheet is too big, the sheet will fall off. If it’s too small, you’ll have trouble getting the elastic over the mattress corners.
As the name suggests, flat bed sheets are meant to lie flat on the mattress. They should be larger than the mattress surface. The extra fabric that hangs over the sides is then tucked under the mattress.
Not to be confused with a comforter, a duvet is a thick blanket that’s filled with down, feathers, wool, silk, or synthetic material. Duvets require a duvet cover sheet that you can take off to clean. This bedding lies on top of the bed and drapes slightly over the edge of the mattress.
Lastly, a bed skirt is a fabric that wraps around the bottom of the mattress. It’s designed to hide the space between the mattress and the floor. This allows you to cover the boxspring and any items that are hiding underneath your bed in storage.
If you’re still unsure if a fitted sheet will fit your mattress, you can easily measure it and find out.
Remove any sheets from your bed and measure the width and length of your mattress. Then measure the height of your mattress, being sure to include any mattress toppers. Write these dimensions down. Your fitted sheet should match or be slightly larger than these dimensions.
Next, measure your fitted sheet. Lay the sheet out to find which side is the length (the longer side). Measure from one corner to the other to find the length measurement. Then measure the shorter side, from corner to corner. This is the width. Lastly, take your fitted sheet and measure along the pocket seam. This will tell you the height.
If these measurements are equal to or slightly larger than your mattress measurement, the fitted sheet should fit. If they are much larger, the sheet might bunch up in the night and come off. If they are smaller, the sheet will not fit.
To make sure you aren’t left with the disappointment of the wrong size sheet, here are a couple of additional items to keep in mind.
Many people want extra support or cushion on their mattress. Mattress toppers will add to the depth or height of the mattress. Be sure to take your full mattress depth into consideration when purchasing fitted sheets. A standard fitted sheet typically has a depth of 12 inches. Deep pocket fitted sheets can fit a depth up to 18 inches.
When you get sheets, the first thing you should do is wash them. Sheets may have been in contact with chemicals in production and transportation, so it’s important to wash them. However, it’s essential that you follow the washing instructions on the label. If your sheets shrink, they probably won’t fit your mattress anymore.
Now that you know everything about bed sheet sizes, you can purchase bedding confidently and know that it will fit perfectly onto your mattress. You’ll be snug in your new sheets in no time. Top off your dreamy oasis with a calming weighted blanket that’s designed for the ultimate relaxation.
