Alaskan King Bed Sheets
An Alaskan King bed is one of the largest mattress sizes available, designed for families, luxury bedrooms, and sleepers who want maximum space. But finding properly fitting Alaskan King bed sheets can be frustrating, because standard bedding sizes simply aren’t made to accommodate a mattress this large.
If you’ve tried king or California king sheets and ended up with exposed edges, slipping corners, or undersized flat sheets, this guide will explain why—and how custom-sized bedding is the only real solution.
What Is an Alaskan King Bed?
An Alaskan King mattress typically measures 108 inches wide by 108 inches long, making it both wider and longer than any standard mattress size.
Because of these dimensions:
-
Standard king sheets are far too small
-
California king sheets only add length, not width
-
“Oversized” sheets are rarely large enough
An Alaskan King bed requires sheets that are specifically designed—or custom-made—for its size.
Why Standard Sheets Don’t Work for Alaskan King Beds
Most sheet manufacturers stop production at standard or California king sizes. Anything larger is often treated as an afterthought.
Common issues include:
-
Fitted sheets that won’t stretch across the mattress
-
Corners popping off during sleep
-
Flat sheets that don’t provide proper drape
-
Poor durability due to overstretching
Even deep pocket sheets fail if the width and length are incorrect, which is almost always the case for Alaskan King mattresses.
Custom Alaskan King Bed Sheets: The Best Fit Solution
The most reliable way to get properly fitting Alaskan King bed sheets is to choose custom-sized bedding.
Custom sheets are made using:
-
Exact mattress width and length
-
Mattress depth (including pillow tops or toppers)
-
Reinforced elastic designed for oversized corners
The result is:
-
Full mattress coverage
-
Sheets that stay in place all night
-
A clean, tailored bed appearance

Best Materials for Alaskan King Bed Sheets
Because Alaskan King beds use a large amount of fabric, material quality plays a major role in comfort and longevity.
Recommended options include:
-
Egyptian cotton for breathability and softness
-
Percale weave for a crisp, hotel-style feel
-
Sateen weave for a smooth, elevated finish
High-quality materials ensure oversized sheets remain durable, maintain shape, and feel comfortable year-round.

How to Measure an Alaskan King Mattress Correctly
Even Alaskan King mattresses can vary slightly by manufacturer, so accurate measurements are essential.
Follow these steps:
-
Measure width from side to side
-
Measure length from head to foot
-
Measure depth, including any pillow top or mattress topper
Always measure the mattress itself—not the bed frame or old sheets—to ensure a precise custom fit.
Who Should Choose Alaskan King Bed Sheets?
Alaskan King bed sheets are ideal for:
-
Families sharing one bed
-
Couples who want maximum personal space
-
Luxury or custom-built bedrooms
-
Extra-large or square bed frames
If your mattress exceeds Wyoming King dimensions, Alaskan King sheets are not optional—they’re essential.
