Custom Size Fitted Sheets
If your fitted sheet pops off at the corners, bunches up overnight, or never seems to fully cover your mattress, the issue is almost never fabric quality—it’s sizing. Custom size fitted sheets are designed for mattresses that don’t conform to standard dimensions, offering a precise fit that stays smooth, secure, and comfortable night after night.
This guide explains why standard fitted sheets fail, who custom sizing is best for, and how custom-made fitted sheets can completely change your sleep experience.
Why Standard Fitted Sheets Fail on Modern Mattresses
Mattresses today are thicker, taller, and more diverse in size than ever before, yet most fitted sheets are still produced using outdated measurements.
Common problems include:
-
Deep or pillow-top mattresses not fitting into standard pocket depths
-
Oversized beds with extra width or length
-
Mattresses that are slightly longer or wider than labeled sizes
-
RV and custom-built beds with unique dimensions
Even “deep pocket” fitted sheets are often made to generalized limits, which means they stretch unnaturally and lose grip over time.
What Are Custom Size Fitted Sheets?
Custom size fitted sheets are made specifically to your mattress measurements, not a size category like Queen or King.
Instead of guessing, your fitted sheet is tailored using:
-
Exact mattress width
-
Exact mattress length
-
Exact mattress depth
This precision allows the elastic to sit perfectly under the mattress, ensuring:
-
No slipping or corner lift
-
A smooth, tailored surface
-
Consistent comfort throughout the night

Who Needs Custom Size Fitted Sheets?
Custom sizing isn’t just a luxury—it’s a solution for very real bedding challenges.
Deep & Pillow-Top Mattresses
Many modern mattresses exceed 14–16 inches in depth. Custom fitted sheets fully wrap around the mattress without overstretching or tearing.
Oversized & Family Beds
Beds like Wyoming King, Alaskan King, and Family Bed require fitted sheets wider and longer than standard sizes. Browse our Oversized Bedding Collection for these specialty dimensions .
RV & Non-Standard Beds
RV mattresses often follow proprietary sizing. Custom fitted sheets eliminate loose fabric and exposed mattress edges, creating a clean, hotel-style finish.
Best Materials for Custom Size Fitted Sheets
Fit solves the problem—but fabric defines the experience.
High-quality materials commonly used for custom fitted sheets include:
-
Egyptian cotton for softness and breathability
-
Percale weave for a crisp, cool feel
-
Sateen weave for a smoother, more refined finish
A precisely sized fitted sheet in a premium fabric performs better, lasts longer, and maintains its shape wash after wash.
Our Custom Egyptian Cotton Fitted Sheet is designed for both exact sizing and everyday luxury.
How to Measure for Custom Fitted Sheets (Correctly)
Accurate measurements are the foundation of a perfect fit.
Follow these steps:
-
Measure mattress width from side to side
-
Measure mattress length from head to foot
-
Measure mattress depth, including pillow tops or toppers
Important tip: Measure the mattress itself—not the old sheet or the bed frame. Even a one-inch difference can affect how the fitted sheet performs.
Are Custom Size Fitted Sheets Worth It?
If your mattress doesn’t match standard dimensions, custom size fitted sheets are absolutely worth it.
They offer:
-
A consistently secure fit
-
A cleaner, more polished bed appearance
-
Improved comfort with no fabric movement
-
Reduced wear caused by overstretching
Instead of repeatedly replacing ill-fitting sheets, one properly tailored fitted sheet delivers long-term value and better sleep quality.
