Custom Size Sheets: How Custom Bedding Works

Standard sizes work for most beds, but not all of them. Custom size sheets exist for exactly the beds that fall outside the usual Twin-through-California-King lineup, antique frames, adjustable bases, oddly thick mattresses, and everything in between.

Who Actually Needs Custom Size Sheets

Not everyone, but for a specific group of shoppers, standard sizing simply doesn't work. Antique bed frames often run narrower or shorter than modern mattresses. Adjustable bases and hospital-style frames sometimes need shapes standard flat sheets weren't designed for. Extra-thick mattresses and toppers can push past even deep-pocket depth ranges. If any of that sounds familiar, custom sizing solves a problem standard sheets simply can't.

How Kotton Culture's Custom Sizing Works

Custom sizing is offered as an add-on customization service, applied on top of your chosen bedding style. You pick the base product, duvet cover, sheet set, or bedding style you want, then add the custom sizing service so it's cut and finished to your exact measurements instead of a standard size chart.

How to Measure Before You Order

• Measure your mattress or duvet insert directly, length and width, not the bed frame.
• Measure the mattress depth from top to bottom for accurate pocket sizing on fitted sheets.
• Double-check every number before submitting, custom pieces are cut once and aren't easily adjusted afterward.

What You're Actually Paying For

The custom size duvet cover service is a flat $50 charge added to your chosen style. Kotton Culture describes it plainly, perfect bedding doesn't always come in a bag, so the customization option exists specifically to guarantee a fit that a standard size can't promise. It's a straightforward add-on, not a separate confusing product line.

What to Expect With Turnaround

Custom pieces are cut and finished individually rather than pulled from standard inventory, so they naturally take longer to ship than an in-stock size. If you're ordering for a specific date, like moving into a new place or replacing bedding on a bed frame you already own, plan ahead and order with extra lead time built in.

Custom Sizing vs Just Sizing Up

It's tempting to just order the next size up and tuck the extra fabric, and for a small mismatch, that can work fine. But for a genuinely non-standard mattress or insert, sizing up usually means loose, baggy corners on a duvet cover or a fitted sheet that still won't grip properly. Custom sizing solves the actual problem instead of working around it.
