What Is Full Size?
When you hear full size you might wonder if its the same as a double mattress. Spoiler: yes, theyre interchangeable terms. The most common dimensions youll see in product listings are:
| Measurement | Metric (cm) | Imperial (ft/in) |
|---|---|---|
| Width | 135cm | 4ft6in |
| Length | 190cm | 6ft3in |
| Typical European Variant | 140200cm | 4ft7in6ft7in |
These measurements are the full size bed dimensions youll find in most North American stores. If youre shopping overseas, watch for the slightly larger European version it can make a difference when you buy bedding.
How Does It Stack Up?
Its helpful to picture a full sidebyside with the other common sizes. Heres a quick visual comparison in centimeters:
| Bed Type | Width (cm) | Length (cm) |
|---|---|---|
| Twin | 99 | 191 |
| Full (Double) | 135 | 190 |
| Queen | 160 | 200 |
| King | 180 | 200 |
If youve ever tried to imagine a full bed in a cramped studio, think of it as a twin plus an extra 36cm of width. Thats enough space for a single adult to sprawl or a cozy couple to cuddle, but its not as roomy as a queen.
Why Choose Full?
Choosing a full size isnt just about fitting a mattress into a tiny roomthere are genuine pros and cons that can affect your sleep quality and budget.
Benefits Youll Love
- Spacesaving magic: Ideal for small master bedrooms, guest rooms, or even a larger dorm.
- Costeffective: Full mattresses and frame sets usually cost 1525% less than queensize counterparts.
- Versatility: Perfect for single adults, teens, or partners who dont need a lot of room to move.
- Easy to find bedding: Full size bed in cm is a standard size for sheets, blankets, and mattress protectors.
According to a 2024 market analysis by , the average price difference between a full and a queen mattress in the United States is about $180, a noticeable saving for students or firsttime homeowners.
Potential Drawbacks
- Length limitation: If youre taller than 190cm (about 6ft3in), youll likely feel cramped.
- Width for couples: Two adults sharing a 135cm width might find it a bit snug, especially if one of you tends to toss and turn.
- Resale value: While full beds are common, queens tend to have a slightly higher resale market.
One of my friends, Alex, swapped his twin for a full to accommodate his growing teenager. He loved the extra width, but when his boyfriend moved in, they soon realized a queen gave them that wiggle room they needed.
Measuring Your Space
Before you rush to add a full to your cart, make sure it truly fits. Heres a simple, nostress way to measure your room and the mattress you want.
StepbyStep Guide
- Gather a tape measure: A 2meter retractable one works fine.
- Measure width: From the left interior wall to the right interior wall where the bed will sit. Write down the number in centimeters.
- Measure length: From the foot of the wall to the head wall. Add at least 60cm of clearance on either side for nightstands and walking space.
- Check ceiling height: Ensure theres at least 20cm above the headboard for a comfortable headspace.
Pro tip: when you measure the mattress itself, exclude any decorative headboard or footboard that adds extra thickness. Those can add 24cm and might make a tight fit feel even tighter.
Common Pitfalls
- Measuring the frame instead of the mattress: The frame can be a few centimeters larger, causing a mismatch with sheets.
- Forgetting the mattress depth: If you love thick, pillowtop mattresses, add that depth to your clearance calculations.
- Not accounting for bedding: Fitted sheets typically need a 15cm pocket, so a mattress a bit larger than the listed full size may actually be ideal.

Buying Guide: Picking the Perfect Full
Now comes the fun partshopping! Whether youre eyeing an innerspring, memory foam, or hybrid, heres what to think about.
Mattress Types & Comfort
- Innerspring: Classic bounce, great airflow, and usually the most affordable. Look for a coil count of at least 800 for a supportive feel.
- Memory foam: Excellent pressure relief, especially for side sleepers. A 200300mm thickness works well on a full.
- Hybrid: A mix of coils and foam the best of both worlds. Ideal if you want bounce and contouring.
For single sleepers, a mediumsoft rating (around 67 on a 10point scale) often feels just right. Couples tend to prefer a medium firmness, as it balances comfort and support for both parties.
Frame & Support
A sturdy frame prolongs the life of your mattress. Heres what to watch for:
- Slat spacing: No more than 7cm apart to prevent sagging.
- Material: Solid wood offers durability, while metal frames are lighter and often cheaper.
- Height: Aim for a platform that sits 2030cm off the floor, giving you enough room for underbed storage.
