The right bed sheet starts with the type of mattress you want to cover. Fitted sheets have elasticated edges that help keep the sheet securely around the mattress, while flat sheets offer a simple, versatile alternative. For beds with a separate topper or a box spring construction, a sheet designed for that particular mattress type can provide a better fit.
When choosing a fitted sheet, match both the width and length to your mattress and check the mattress depth to ensure the corners fit properly. Common searches such as fitted sheet 90x200 cm, fitted sheet 140x200 cm and fitted sheet 180x200 cm reflect different single and double bed widths, so measuring your mattress before choosing is important.
A box spring sheet is intended to fit around the relevant mattress section of a box spring bed, while a topper fitted sheet is made for a separate mattress topper. The distinction matters because these mattress layers can differ considerably in depth. Choosing a sheet designed for the part of the bed you want to cover helps achieve a neater fit.
A flat sheet is a rectangular piece of fabric without fitted corners. Unlike a fitted sheet, it can be tucked around the mattress, so its dimensions need to allow enough fabric for the way you intend to use it. Sizes such as 150x250 cm may suit narrower beds, while larger dimensions such as 240x260 cm provide more fabric for wider beds. Always compare the sheet dimensions with your mattress rather than relying on the single- or double-bed description alone.
Once you have chosen your sheets, you can pair them with bedding for your duvet and pillows. A bedspread can add an extra decorative layer when the bed is made.
Choose according to the mattress layer you want to cover. A box spring sheet is designed for the relevant mattress section of a box spring bed, while a topper fitted sheet is designed for a separate mattress topper. Check the dimensions and depth of that specific layer before choosing.
Match the fitted sheet to your mattress width and length, and check the mattress depth as well. A sheet with the correct width and length can still fit poorly if its corners are not suitable for the mattress depth.
Allow enough fabric beyond the mattress dimensions for the amount you want to tuck underneath. Because flat sheets do not have fitted corners, sizes such as 150x250 cm or 240x260 cm should be compared directly with your mattress dimensions and your preferred amount of overhang.
