But this also brings a challenge: how do you find the right size bed sheets for a mattress that isn\u2019t standard?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Poorly fitted sheets can be frustrating. Fitted sheets may pop off the corners. Flat sheets may not cover the sides fully or can bunch up with too much excess fabric. This guide will help you choose the right custom size fitted sheet and custom size flat sheet based on your actual mattress dimensions, so your bed always looks clean and feels comfortable.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Fitted Sheet: Match Mattress Size and Add Extra Depth<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A fitted sheet is designed to wrap around your mattress and stay securely in place.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The length and width of the fitted sheet should match your mattress exactly.<br><\/li>\n\n\n\n<li>The depth (or mattress height) of the sheet should be 3 to 5 cm more than your actual mattress height. This extra fabric allows the sheet to tuck under the mattress securely and stay in place, even if your mattress is extra thick or has a topper.<br><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Example:<br>If your mattress is 180 cm wide, 200 cm long, and 30 cm deep, your <a href=\"https:\/\/www.ellesilk.com\/deep-pocket-silk-fitted-sheet.html\">custom fitted sheet<\/a> should be<br>180 cm x 200 cm x 33\u201335 cm (depth).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This ensures a snug fit that doesn\u2019t pull loose overnight.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Flat Sheet: Use a Clear Formula for the Best Fit<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A flat sheet should drape neatly over the sides and foot of your mattress. For custom sizes, we use the following formula to calculate the right dimensions:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Flat Sheet Length = Mattress Length + 2 \u00d7 Mattress Depth \u2212 10 cm<br>Flat Sheet Width = Mattress Width + 2 \u00d7 Mattress Depth + 20 cm<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This gives you a tailored fit that\u2019s not too tight or too loose.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/www.ellesilk.com\/custom-silk-bedding.html\"><img loading=\"lazy\" decoding=\"async\" width=\"1020\" height=\"600\" src=\"https:\/\/www.ellesilk.com\/blog\/wp-content\/uploads\/silk-bedding-2021-2.jpg\" alt=\"silk bedding\" class=\"wp-image-19972\" srcset=\"https:\/\/www.ellesilk.com\/blog\/wp-content\/uploads\/silk-bedding-2021-2.jpg 1020w, https:\/\/www.ellesilk.com\/blog\/wp-content\/uploads\/silk-bedding-2021-2-300x176.jpg 300w, https:\/\/www.ellesilk.com\/blog\/wp-content\/uploads\/silk-bedding-2021-2-768x452.jpg 768w, https:\/\/www.ellesilk.com\/blog\/wp-content\/uploads\/silk-bedding-2021-2-102x60.jpg 102w\" sizes=\"auto, (max-width: 1020px) 100vw, 1020px\" \/><\/a><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Why This Formula Works<\/strong><\/h3>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Flat Sheet Width = Mattress Width + 2 \u00d7 Depth + 20 cm<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The goal is to have the flat sheet fully cover the sides of your mattress and drape beyond the edge a little for a clean look.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The \u201c2 \u00d7 depth\u201d part ensures the sheet can drop down on both sides of the mattress.<br><\/li>\n\n\n\n<li>The extra 20 cm means the sheet will hang an additional 10 cm below the mattress on each side.<br><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This extra drop on both sides gives a soft, luxurious look and allows the sheet to be tucked under easily.<br>If you prefer less drape, you can reduce the extra length\u2014for example, add just 10 cm total\u2014but keep in mind that this value is split across both sides, so you need to calculate for both.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Flat Sheet Length = Mattress Length + 2 \u00d7 Depth \u2212 10 cm<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">This may look a bit unusual, but it\u2019s based on how people typically make their beds.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The foot of the bed usually needs more fabric to tuck in.<br><\/li>\n\n\n\n<li>The head of the bed, however, often sits against a wall or headboard, and doesn&#8217;t need extra length or draping.<br><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">That\u2019s why we subtract 10 cm from the total length\u2014it reduces excess fabric at the top, helps your sheet lay flatter, and makes the bed easier to manage.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Example Calculation<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If your mattress measures:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Length: 213 cm<br>Width: 213 cm<br>Depth: 36 cm<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Your flat sheet size would be:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Length = 213 + 2 \u00d7 36 \u2212 10 = 275 cm<br>Width = 213 + 2 \u00d7 36 + 20 = 305 cm<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">So your <a href=\"https:\/\/www.ellesilk.com\/custom-silk-sheets-be006.html\">custom size flat sheet<\/a> should be 275 cm x 305 cm. This will give you a clean, balanced fit with a natural drape on all sides where it\u2019s needed.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Why Custom Sizing Matters<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The right sheet size improves both comfort and appearance. Sheets that are too tight can ride up; sheets that are too loose can bunch and look messy. When you use custom-sized sheets based on your actual mattress dimensions, you get:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>A better sleep experience<br><\/li>\n\n\n\n<li>A bed that looks well made<br><\/li>\n\n\n\n<li>Less hassle when making your bed<br><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Let us know your mattress dimensions, and we\u2019ll help you find the perfect fit.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Many people today use mattresses that don\u2019t follow standard sizing, especially in the US and European markets where custom-made mattresses are becoming more popular.
