Quick Answer: A double bed (full) measures 54" x 75" while a queen is 60" x 80", giving you six extra inches of width and five more inches of length. For couples, the queen is almost always the better choice. For solo sleepers in smaller rooms, a double works well.

At Mattress Miracle, 441 1/2 West Street, Brantford, Ontario, we have been helping families choose the right mattress size since 1997. The double vs queen bed question comes up almost every day in our showroom. Both sizes have their place, and the right answer depends on who is sleeping in the bed, the size of your bedroom, and your budget. This guide breaks down every detail so you can decide with confidence.
Double vs Queen Bed: Exact Dimensions Compared
The difference between a double vs queen bed is more meaningful than most people expect. That extra width and length changes how you sleep, how your bedroom feels, and what bedding you need to buy.
| Feature | Double (Full) | Queen |
|---|---|---|
| Width | 54 inches (137 cm) | 60 inches (152 cm) |
| Length | 75 inches (190.5 cm) | 80 inches (203 cm) |
| Surface Area | 4,050 sq. inches | 4,800 sq. inches |
| Per-Person Width (Couple) | 27 inches each | 30 inches each |
| Best For | Solo sleepers, teens, guest rooms | Couples, taller individuals |
A queen bed gives you roughly 18.5% more sleeping surface than a double. That is a noticeable difference when you are sharing the bed with a partner, a pet, or a child who wanders in at 3 a.m.
For solo sleepers, a double is comfortable and leaves more floor space for other furniture. For couples, 27 inches per person on a double is tighter than a standard crib mattress. The queen's 30 inches per person is better, though still modest.
Why Width Matters More Than You Think
The average adult shoulder width is 16 to 18 inches. On a double bed shared by two people, that leaves roughly 9 to 11 inches of extra space per person for arm movement and shifting positions during the night. A queen adds three more inches per side. If either sleeper tends to roll or spread out, that extra space makes a real difference to uninterrupted rest.

All Bed Sizes Compared (Including UK Sizes)
Whether you are shopping in Canada, the United States, or comparing bed sizes UK standards, it helps to see everything side by side. Mattress Miracle carries Canadian and North American standard sizes, and we often get questions from customers who have moved here from the UK or are ordering bedding internationally.
North American Standard Sizes
| Size | Width x Length (inches) | Width x Length (cm) |
|---|---|---|
| Twin | 38" x 75" | 96.5 x 190.5 cm |
| Twin XL | 38" x 80" | 96.5 x 203 cm |
| Double (Full) | 54" x 75" | 137 x 190.5 cm |
| Queen | 60" x 80" | 152 x 203 cm |
| King | 76" x 80" | 193 x 203 cm |
| California King | 72" x 84" | 183 x 213 cm |
UK Bed Sizes for Reference
If you are comparing bed sizes UK to Canadian standards, here is a helpful reference. UK sizes do not match North American sizes exactly, which matters if you are ordering bedding from overseas or furnishing a home after relocating.
| UK Size | Width x Length (inches) | Closest Canadian Equivalent |
|---|---|---|
| UK Single | 36" x 75" | Twin (slightly wider) |
| UK Double | 54" x 75" | Canadian Double (same) |
| UK King | 60" x 78" | Close to Queen (queen is 2" longer) |
| UK Super King | 72" x 78" | Between King and Cal King |
One thing that catches people off guard: a UK king is roughly the same width as a Canadian queen. If you are ordering sheets or a duvet cover from a UK retailer, double-check the centimetre measurements rather than relying on the size name.
Room Size Requirements for Each Bed Size
The mattress is only part of the equation. You need enough room to walk around the bed, open dresser drawers, and avoid that cramped feeling that makes a bedroom uncomfortable.
Minimum Room Sizes We Recommend
- Twin bed: 7' x 10' (70 sq. ft.) for a child's room or small guest room
- Double bed: 9' x 10' (90 sq. ft.) for comfortable movement on both sides
- Queen bed: 10' x 10' (100 sq. ft.) for a couple with nightstands
- King bed: 12' x 12' (144 sq. ft.) for proper clearance all around
- California King: 12' x 12' (144 sq. ft.), same as king but longer, so account for length
If your bedroom is between 90 and 100 square feet, the double vs queen bed decision often comes down to what else needs to fit. A double leaves room for a desk or a reading chair. A queen fills the space more but gives you better sleep.
Brantford Bedroom Sizes
Many older Brantford homes, especially the character homes in Eagle Place and the downtown core, have bedrooms on the smaller side. A double bed often fits these rooms better than a queen. Newer builds in areas like Shellard Lane and the west end tend to have primary bedrooms large enough for a queen or even a king. If you are not sure what will fit, bring your room measurements to Mattress Miracle and we will help you figure it out.
Choosing the Right Bedding and Accessories
Once you pick your mattress size, you need bedding that actually fits. This is where people run into trouble, especially with less common sizes like the California King.
Sheets and Fitted Sheets
Standard fitted sheets work for most mattresses up to about 12 inches deep. If your mattress is thicker (many modern mattresses are 13 to 15 inches), you need deep fitted queen sheets or deep pocket sheets. These have elastic that stretches to accommodate mattresses up to 18 inches deep, so your corners stay tucked all night instead of popping off at 2 a.m.
Mattress Miracle carries queen size mattresses and double mattresses in a range of thicknesses. If you are buying a thicker pillow-top or euro-top model, ask us about compatible deep pocket sheets.
Duvet Covers and Bedspreads
Sizing gets especially tricky at the king level. A standard king duvet cover fits a 76" x 80" king comforter. A California king duvet cover is narrower but longer at roughly 104" x 98", designed for the 72" x 84" California king mattress. These are not interchangeable. A regular king duvet on a California king bed will hang over the sides but leave your feet exposed.
An oversized king duvet cover is a third option that works well for anyone who wants generous drape on either a standard king or California king. These typically measure 112" x 98" or larger and give you extra fabric to tuck or let hang. If you and your partner tend to fight over the covers, an oversized duvet solves the problem without needing separate blankets.
For a standard or California king, a California king bedspread should also be sized specifically. A regular king bedspread will not provide enough length coverage on a Cal king mattress.
Pillow Arrangement for Every Bed Size
A good queen bed pillow arrangement makes the bed look put together without taking 10 minutes every morning. Here are practical setups that work.
Queen Bed Pillow Arrangement
The simplest pillow arrangement queen bed setup uses two standard or queen-size sleeping pillows side by side, then two decorative shams in front. That is four pillows total. If you want a bit more depth, add a single lumbar or bolster pillow in front of the shams. Keep it to five pillows maximum. More than that and you are spending more time arranging pillows than sleeping on them.
Twin Bed Pillow Setup
For a pink twin bed or any styled twin bed, one standard sleeping pillow with one decorative sham in front is plenty. A small accent pillow adds a pop of colour without overwhelming the smaller surface.
King Bed Arrangement
Three king-size pillows across the back, two shams in front, and one accent pillow. The three-pillow back row fills the full 76-inch width cleanly.
Bed Frames and Support Options
Your mattress needs proper support underneath. The wrong frame or no frame at all will void most warranties and shorten the life of your mattress.
Slats for Queen Bed
If you are using a platform frame or building your own, slats for queen bed frames should be no more than 3 inches apart. Wider gaps let the mattress sag between slats, creating pressure points and accelerating wear. Most foam and hybrid mattresses require slats that are 2.5 to 3 inches apart with a centre support beam for a queen.
Mattress Miracle carries bed frames and box springs that are matched to the mattresses we sell. When you buy a mattress from us, we make sure the support system is right for that specific model.
DIY Twin Bed Frame
A DIY twin bed frame is a popular weekend project, especially for a child's room or a guest room. The key measurements to get right are the interior opening (38" x 75" for a standard twin, 38" x 80" for a twin XL) and the slat spacing. Use 1x4 lumber for slats, spaced 2.5 inches apart, and secure them with a centre rail for stability. A twin XL mattress is worth considering if the sleeper is taller, since it adds five inches of length for the same width.
Twin Beds with Storage: A Smart Solution
Twin beds with storage and headboard designs are especially useful in smaller bedrooms. Built-in drawers underneath the frame use otherwise wasted space for extra linens, seasonal clothing, or toys. If you are building a DIY frame, consider adding a simple drawer system on full-extension slides. For a ready-made option, ask us about twin frames with integrated storage next time you visit the showroom.
A Note on Viking Beds
A viking bed is a traditional Scandinavian-style bed frame, usually a simple solid wood platform with minimal ornamentation. These frames have seen a resurgence in modern bedroom design because of their clean lines and sturdy construction. If you are drawn to this aesthetic, make sure the interior dimensions match a standard North American mattress size, since imported Scandinavian frames sometimes use European sizing that is slightly different.
What to Expect on Pricing
In general, a queen mattress costs 10 to 20 percent more than the same model in a double. The difference varies by brand and construction, but it is rarely dramatic. At Mattress Miracle, we carry double mattresses and queen mattresses across a range of price points.
Bedding costs also scale up with size. Queen sheets, duvet covers, and mattress protectors cost a bit more than double, and king and California king bedding is the most expensive. An oversized king duvet cover or California king duvet cover can be harder to find in stores, so plan ahead if you are going with a less common size.
The best value is almost always buying the right size the first time. Upgrading a mattress after a year because it is too small is far more expensive than spending the extra hundred dollars upfront.

Can two adults sleep comfortably on a double bed?
They can, but it is tight. Each person gets 27 inches of width, which is less than the width of a standard crib. For occasional use in a guest room, a double works fine for a couple. For every night, most couples are happier on a queen or larger. Come try both sizes at Mattress Miracle in Brantford to feel the difference for yourself.
Will queen sheets fit a double bed?
Queen flat sheets will work on a double, though they will hang a bit lower on the sides. Queen fitted sheets will not stay on a double mattress properly because the elastic is sized for the larger dimensions. Always buy fitted sheets that match your exact mattress size, especially if you need deep fitted queen sheets for a thicker mattress.
What is the difference between a California king and a regular king?
A California king is 4 inches narrower but 4 inches longer than a standard king (72" x 84" vs. 76" x 80"). Choose a Cal king if you are taller than 6 feet and want the extra legroom. The trade-off is slightly less side-to-side space. Remember that California king duvet covers and bedspreads are sized differently than regular king bedding.
How far apart should slats be for a queen bed frame?
Slats should be no more than 3 inches apart, with a centre support beam running the length of the frame. This prevents sagging and protects your mattress warranty. If you are building a DIY frame, 2.5-inch spacing is ideal for most foam and hybrid mattresses.
