Are Ikea Mattress Sizes Standard? A Clear Guide to What Fits and What Doesn’t
If you’re asking “Are Ikea mattress sizes standard?”, you’re likely trying to figure out whether a mattress from a large home-furnishing store will fit your existing bed frame, sheets, or mattress topper. This guide walks through how these sizes compare to typical dimensions and what you need to watch out for before you buy.
Are Ikea Mattress Sizes Standard Compared to Typical Sizes?
In many regions, Ikea mattress sizes are not exactly the same as local “standard” sizes, even when the names sound familiar (like twin, full, queen, or king).
Broadly:
- Some sizes are very close to common standards.
- Others can be several centimeters or an inch or two different in width or length.
- These differences can affect how well the mattress fits non-matching frames and bedding.
Because of this, the safest approach is to treat these mattresses as having their own size system, even if some measurements overlap with common sizes in your country.
Why Does It Matter If Ikea Mattress Sizes Are Standard?
Whether Ikea mattress sizes are standard matters for a few practical reasons:
- Bed frames: A mattress that’s shorter or narrower than your frame can leave gaps.
- Sheets and protectors: Fitted sheets might be too loose or too tight if the sizes don’t line up.
- Mattress toppers and pads: A topper in a standard size may hang over the edges or fall short.
- Room planning: If you’re planning layouts precisely, a few centimeters can make a difference in tight spaces.
Knowing in advance helps you avoid returns, frustration, and mismatched accessories.
How Do Ikea Mattress Sizes Compare to Common Bed Sizes?
While exact numbers vary by region, the key point is that these mattresses often differ slightly from what many people consider standard. Length is often the biggest difference.
Here’s a simplified example of how this can play out:
| Label on Mattress | Typical “Standard” Expectation* | Common Ikea Difference* |
|---|---|---|
| Twin / Single | Often ~190–191 cm long | Often closer to 200 cm long |
| Full / Double | Often ~135 × 190 cm | May be slightly different in both dimensions |
| Queen | Often ~150 × 200 cm | Sometimes close, but can vary |
| King | Often ~180 × 200 cm | Sometimes close, but not identical |
*Dimensions here are generalized examples, not exact or universal. Measurements vary by country.
The main takeaway: names can sound familiar, but actual measurements may not match your local standards exactly. Always check the product dimensions, not just the label.
Will Ikea Mattresses Fit Non‑Ikea Bed Frames?
Often, they can fit reasonably well, but there are a few common scenarios:
1. Mattress Slightly Longer or Shorter
If the mattress is longer than your frame’s standard size, it may:
- Bump against a footboard
- Make it harder to tuck sheets
- Slightly protrude beyond the frame
If it’s shorter, you may notice:
- A small gap between the mattress and headboard/footboard
- Pillows tending to slide into the gap at the head
- A visible space at the end of the bed
2. Mattress Slightly Wider or Narrower
A wider mattress may:
- Sit on top of side rails or feel squeezed
- Cause fitted sheets designed for the frame’s original size to fit oddly
A narrower mattress may:
- Leave small gaps along the sides
- Make the bed feel less snug or “finished”
In many cases, these differences are minor, but for a perfect fit, matching frame and mattress systems usually work best.
Can I Use Standard Sheets and Bedding on an Ikea Mattress?
You often can, but fit can vary depending on the specific size difference.
- Fitted sheets: These are the most sensitive to small differences. A slightly longer mattress may stretch a sheet tightly; a shorter one may leave extra loose fabric.
- Flat sheets and duvets: These are generally more forgiving, since they aren’t tightly cut to exact dimensions.
- Mattress protectors and toppers: These may fit best when they match the mattress’s specific dimensions, not just the size label.
If you already own standard-size bedding, it may still work, but expect the fit to be “good enough” rather than perfectly tailored in some cases.
How Do I Make Sure I Get the Right Size?
When wondering “Are Ikea mattress sizes standard?”, the most reliable answer comes from measuring and comparing, not from the naming alone.
🔍 Simple steps to check compatibility:
Measure your frame’s internal space
- Measure the usable sleeping area: length and width inside the rails or between headboard and footboard.
Compare to the mattress dimensions
- Use the exact measurements in centimeters or inches, not just “twin,” “full,” “queen,” or “king.”
Allow for a small tolerance
- A difference of around 1–2 cm (or roughly ½ inch) is often workable. Larger differences may be more noticeable.
Think about bedding as well
- If your fitted sheets are cut very precisely, a length or width difference of a few centimeters may affect how snugly they fit.
✔️ Quick Mattress Takeaways
Key points consumers should understand about “Are Ikea Mattress Sizes Standard”
- Ikea mattress sizes are not always identical to local standards, even when the names sound the same.
- Length differences are particularly common, and width can vary slightly too.
- Standard sheets and frames can sometimes work, but the fit may not be perfect.
- Always check the exact dimensions of both your frame and the mattress before pairing them.

Understanding the real answer to “Are Ikea mattress sizes standard?” comes down to one thing: never rely on the size name alone. With a quick measurement and comparison, you can confidently choose a mattress that fits your frame, your bedding, and your space.
