02 / Three measurements
Measure the whole mattress
A fitted sheet needs the right footprint and enough wall depth to wrap around your mattress. Include any topper, underlay or protector sitting beneath it.

Fitted, flat or extra depth?
Fitted sheets
Match the mattress size and depth. A deeper Queen still needs a Queen footprint. Extra-depth Queen and King sheets provide deeper walls for those sizes.
Names such as Mega and Super vary by range. A true Super King fitted sheet has a wider footprint than King Extra Depth.

Check the finished width and length. Think about the side drape and fabric you want to tuck at the foot. Flat sheets have no fitted wall.
Measurements can differ between ranges with the same size name. Check set contents for the included flat sheet and pillowcases.

Long Single, King Single & Split King
Long Single and King Single share a similar length but have different widths. Their fitted sheets are not interchangeable.
A Split King commonly combines two Long Single mattresses, each with its own fitted sheet. Measure each side independently, particularly on adjustable beds. Check the listing for the shared flat sheet and pillowcases.

400TC White Split King Extra Depth Sheet Set
Compare customer experiences with the measurements of this specific cotton sateen set. It includes two fitted sheets, each 91 × 203 × 50 cm, a 300 × 274 cm flat sheet and two 48 × 73 cm pillowcases. Measure each mattress and any topper before choosing.
Reviews relate to this item. Individual experiences of feel and adjustable-bed fit can vary.
Check the finishing layers, too
A mattress protector needs the right footprint and depth; waterproofing and allergen barriers depend on its construction. Match pillowcases and pillow protectors to your pillow’s actual dimensions. Choose a quilt cover to match the quilt insert, which may be larger than your mattress.
A few common questions
Will a bigger fitted sheet solve a deep mattress?
Choose the correct mattress footprint with a suitable wall depth. Moving to a wider size can leave loose corners. Measure your topper and mattress together, then check the specific product’s fit advice.
Are all Queen flat sheets the same size?
No. Finished measurements vary by range. Compare width and length with your mattress, allowing for side coverage and your preferred tuck at the foot.
What sheets do I need for a Split King?
Usually two Long Single fitted sheets, one for each mattress. Confirm each half’s dimensions and depth, then check whether the set includes a shared flat sheet and pillowcases.
