What Mattress Bag Size Do I Need?
Use your measurements for mattress width, mattress length, and mattress thickness to find mattress-bag fit.
Enter your measurements
Use this fit check when you need to answer “what mattress bag size do i need?” Enter mattress width, mattress length, and mattress thickness and the tool returns mattress-bag fit using the rule defined for this exact use case.
- Mattress width — Required
- Mattress length — Required
- Mattress thickness — Required
- Insertion allowance each dimension — Required
- Bag internal width — Required
- Bag internal length — Required
- Bag gusset/depth — Required
Mattress-bag fit
Enter the measurements above to calculate mattress-bag fit.
How the calculation works
For this tool, the calculation is requiredWidth=mattressWidth+insertionAllowance; requiredLength=mattressLength+insertionAllowance; requiredDepth=mattressThickness+insertionAllowance; fitPass=requiredWidth≤bagWidth AND requiredLength≤bagLength AND requiredDepth≤bagDepth. That produces mattress-bag fit without borrowing assumptions from unrelated calculators.
Worked example
Example: Mattress width = 94.88 cm; Mattress length = 62.26 cm; Mattress thickness = 19.96 cm; Insertion allowance each dimension = 8.3 cm; Bag internal width = 115.28 cm; Bag internal length = 111.17 cm; Bag gusset/depth = 113.35 cm. Result: Fits; Required Depth = 28.26 cm; Required Length = 70.56 cm; Required Width = 103.18 cm.
Before you decide
Use measured dimensions rather than nominal labels. This page calculates the stated geometry or quantity only; product-specific construction or installation details can still affect the final choice. For what mattress bag size do i need, the limiting result on this page is mattress-bag fit.
Direct measurement/geometry calculation. No external reference is required for the arithmetic itself; the result is derived only from the user-entered measurements and the formula stored in calculationLogicJson.
Frequently asked questions
How does the Mattress Bag Size Fit | What Fits? calculator work?
It uses requiredWidth=mattressWidth+insertionAllowance; requiredLength=mattressLength+insertionAllowance; requiredDepth=mattressThickness+insertionAllowance; fitPass=requiredWidth≤bagWidth AND requiredLength≤bagLength AND requiredDepth≤bagDepth. The result is mattress-bag fit.
Which measurements or specifications do I need?
Use these inputs: Mattress width, Mattress length, Mattress thickness, Insertion allowance each dimension, Bag internal width, Bag internal length, Bag gusset/depth. Measure or copy the values from the exact product/specification rather than guessing.
Is the result a guarantee that the product will fit or be suitable?
No. The calculator answers the stated mattress-bag fit question. Manufacturer instructions, safety rules, certification, installation tolerances or brand-specific size charts can impose additional requirements.
