How to Measure Your Mattress for a Sheet Set
Materials
Tape Measure
Dimensions
Width is the measurement from left to right across the top of the mattress
Length is the measurement across the top of the mattress from the head to the foot
Depth is the measurement of thickness from the highest point on the top edge of the mattress to the bottom edge
Directions
First, consult the mattress dimensions chart and select the correct mattress size.
(Measure the width and length of the mattress, if you are unsure.)
Next, measure the depth of the mattress.
Read the product description for the fitted sheet, which should list the mattress depth that the pockets will accommodate.
Compare your new dimensions to the fitted sheet sizes.
Example
You consult the mattress dimensions chart; you determine that your mattress is a Queen size.
Next, you measure the mattress depth as 15".
You read that the fitted sheet will fit a mattress up to 17" deep.
You would choose the Queen size for this fitted sheet, since it will accommodate your 15" deep mattress.
