Choosing bassinet sheets for a 33 x 17 inch mattress comes down to three numbers: length, width and thickness. Our Organic Muslin Bassinet Sheets, 2-Pack are sized for that mattress, so we use them to show how each check works. The sections below cover the listed size, mattress thickness, mattress outline, fabric, edges, pack count and care. A use-case table and a Q&A follow.
Read the Listed Size on Bassinet Sheets
The listed size is the first number to match. Our bassinet sheets measure 33 x 17 inches, and they are sized specifically for 33 x 17 in bassinet mattresses.
Measure your own mattress with a tape before you compare. Write down its length, width and thickness, then set each figure beside the sheet's listed numbers.
Check Mattress Thickness Against Sheet Depth
Length and width are only two of the three numbers. The third is thickness. Our sheets have a 4 in pocket depth and fit a bassinet mattress up to 4 in (10 cm) thick.
That limit is part of the design: these sheets are made for mattresses up to 4 inches thick only. If your mattress is thicker than 4 inches, look for a sheet whose listed depth covers it.
Match the Mattress Outline to the Sheet
Length, width and thickness describe a mattress's size, not its outline. Look at your mattress's outline as well, and confirm it is a bassinet mattress listed at 33 x 17 in. Our sheets are made for bassinet mattresses of that size only.
Compare Bassinet Sheet Fabric
Our sheets are 100% organic cotton muslin. The muslin is breathable and gets softer with every wash.
Compare Edges and Elastic
Our sheets have fully elasticated edges, which help the sheet hold a snug fit and stay in place through the night. When you compare other fitted sheets, check how far the elastic runs around the edge.
Weigh Pack Count and Care
Each set includes 2 fitted bassinet sheets, so one can stay on the mattress while the other is in the wash. The sheets are machine washable.

Final Thoughts on Choosing Bassinet Sheets
The deciding variable is your mattress's measured length, width and thickness. If it measures 33 x 17 inches and is up to 4 inches thick, these sheets are generally a suitable fit. A thicker mattress or a different size points to a sheet with a different listed size or depth.
