You will need a tape measure or a ruler.

Measure the width of the mattress from one side to the other. Start at the widest point, which is usually from seam to seam or from edge to edge.

Measure the length of the mattress from the head to the foot. Again, start at the longest points.

Measure the depth or height of the mattress. For this, measure from the base to the highest point. Most mattresses fall within the range of 8 to 18 inches in depth.

If you have a pillow-top mattress, remember to include the additional thickness of the pillow-top when measuring the depth. Pillow-top mattresses are often thicker than standard ones.

Refer to the measurements you've taken to determine the appropriate sheet size. Standard sheet sizes include Twin, Twin XL, Full, Queen, King, & California King.

When picking bed sheet sizes, most people forget to take the mattress measurements into consideration. This is why their bed sheet ends up smaller than expected. Here are 4 simple steps on how to measure mattress size for bed sheets. Remove any existing bed sheet from the mattress. Ensure the mattress is flat on the bed and not elevated by anything. Now take a measuring tape and measure the longest side from top to bottom (usually vertical) of the mattress. This is the length. Similarly, measure the shorter side of the mattress from left to right (usually horizontal). This is the width. Lastly, pick a corner of the mattress and measure it vertically from top to bottom seam. If your mattress has a topper, measure it along with the topper. Add the mattress height measurement to the length to buy the right size flat bed sheet. Otherwise, this height dimension can be used to determine the optimal pocket size of a fitted bed sheet. For instance, if mattress length = 80 inches and mattress height = 5 inches, then total mattress length = 85 inches. The bedsheet measurement should always be a tad bigger than the mattress measurement. For instance – if your mattress measures 55x85 inches, the ideal flat bed sheet size will be 60x90 inches. Likewise, the ideal fitted bed sheet size for the same mattress will be 85x90 inches with a 5-inch
