Mattress Depth vs. Pocket Depth
When referring to bed sheets, what exactly does ‘pocket depth’ mean? Many people get confused between ‘mattress depth’ and ‘pocket depth’. Simply put, the mattress depth refers to the thickness of a mattress and pocket depth is the length of the corner seam on a fitted sheet.
In order for sheets to fit properly on a bed, the fitted pocket depth needs to be only one to three inches deeper than the depth of the mattress. Many fitted sheets in the stores these days are made with very deep pockets to accommodate all mattress depths. The standard deep pocket sheets work well for the very deep mattresses, however with the new trend of shallow mattresses now on the market, with some being as shallow as six inches, the standard 15” to 18” fitted pockets are too loose and create uncomfortable bunching and wrinkling in the sleep surface.
If you have experienced this problem, believe it or not, there is a solution. Cozytown Linens offers fitted sheets in one inch intervals ranging from 6” up to 25” deep. It’s a one-of-a-kind custom service at a non-custom price, allowing you to choose the pocket depth that best fits your specific mattress.
Thank you, thank you, thank you!
I have this problem and could not figure out what to do. The stores that sell sheets had no idea other than under- the-mattress garter belts to tighten the fitted sheet, which really didn’t work. I was beginning to feel like the old Prince and the Pea story and thought the problem was me sensitivity to the sheets bunching-up.
So, here’s my question: What pocket depth should I buy of your Bamboo sheets for my 11″ thick Simmons BeautyRest 60X80 Queen mattress?
And thank you.

Hi Peter,
This is a very common question and a very important one as well. For a proper fit, the pocket depth of the fitted sheet should be one or two inches deeper than the depth of the mattress. This will allow a little extra for tucking under the mattress, yet not so much that it causes wrinkling and bunching in the sleep surface. For example, if the mattress measures 11” deep, a fitted pocket depth of 12” or 13” should work fine and give a taut fit.
