Actual measurements, room requirements, and when each size makes sense
Reading Time: 8 minutes
A queen mattress measures 60" x 80" (152 x 203 cm). A king measures 76" x 80" (193 x 203 cm). The king is 16 inches wider, requiring a bedroom of at least 12 x 12 feet for comfortable movement. The Canadian Sleep Society recommends choosing based on your room dimensions first, then sleep partner needs.

The Actual Dimensions (Not Approximations)
There's a surprising amount of confusion about mattress sizes online. Some sites round the numbers, others mix up Canadian and US measurements (they're the same, for the record). Here are the exact dimensions for every standard size sold in Canada.
Canadian Mattress Size Chart
- Twin: 38" x 75" (96.5 x 190.5 cm) - One person, smaller frame
- Twin XL: 38" x 80" (96.5 x 203 cm) - One person, taller frame
- Full/Double: 54" x 75" (137 x 190.5 cm) - One person who likes space, or a very close couple
- Queen: 60" x 80" (152.5 x 203 cm) - Most popular for couples
- King: 76" x 80" (193 x 203 cm) - Couples who want space (full king dimensions)
- California King: 72" x 84" (183 x 213 cm) - Taller people (narrower but longer than king)
- Split King: Two Twin XLs side by side (76" x 80") - Couples with different firmness needs
The difference between a queen and king comes down to 16 inches of width. That's it. Same length, same 80 inches head to foot. Those 16 extra inches translate to 8 inches more per person when you split it down the middle.
Eight inches doesn't sound like much on paper. In practice, it's the difference between brushing elbows with your partner and having room to stretch.
Room Size: The Factor Most People Forget
Here's where the queen vs. king decision often gets made for you: your bedroom.
A mattress needs breathing room. You need space to walk around the bed, open drawers, and not feel like the bed is consuming the entire room. Here's what actually works.
Minimum Room Sizes
Queen mattress: Fits comfortably in a 10' x 10' room (100 sq ft). You'll have room for two nightstands and a dresser. In a 10' x 12' room, it feels generous with space for a reading chair or bench at the foot.
King mattress: Needs a minimum 12' x 12' room (144 sq ft). In a 12' x 14' room, it feels balanced. In anything smaller than 12' x 12', a king makes the room feel cramped, and you'll struggle to fit standard bedroom furniture.
We've had customers who bought a king, got it home, and realized it left 18 inches between the bed frame and the wall. That's technically walkable, but it doesn't feel good. Measure your room before you visit, not after.
The Doorway and Stairway Check
This is the practical consideration nobody mentions until delivery day. A king mattress is 76 inches wide. Standard interior doorways in Canadian homes are 32-36 inches. Hallways are typically 36-42 inches.
A king mattress can be maneuvered through these spaces, but it requires turning it on its side and angling it around corners. If you have a tight staircase with a landing turn, measure the clearance. Our delivery team handles this regularly for Brantford homes, and they'll tell you upfront if there's a concern. Some older homes in areas like Eagle Place and the downtown core have narrower hallways that need careful planning.
When a Queen Makes More Sense
A queen is the right choice more often than the mattress industry would like you to believe. If every couple bought a king, the average sale price would jump. That's not a conspiracy - it's just the economics of the business. So here's an honest take on when queen is the better call.
- Your bedroom is under 12' x 12'. The room will feel and function better with a queen. This is the single biggest factor.
- You're a couple who sleeps close together. Some couples naturally gravitate toward each other at night. If that's you, a queen gives you plenty of room.
- Budget matters. Queen mattresses cost 15-25% less than kings in the same model. The bedding (sheets, duvet covers, mattress protectors) is also cheaper. Over the life of the mattress, the savings add up. Check our best mattresses under $1,000 for options.
- You move frequently. Queens are easier to transport, fit through more doorways, and require smaller moving trucks.
- Guest rooms. A queen is more than adequate for a spare bedroom. A king in a guest room is overkill unless the room is large.
When a King Is Worth the Upgrade
A king mattress is one of those things that, once you've slept on one, is hard to go back from. Here's when it genuinely makes a difference.
- Your room is 12' x 12' or larger. If the space allows it, a king transforms how a bedroom feels. It becomes a room you want to spend time in, not just sleep in.
- One or both of you is a restless sleeper. If your partner tosses and turns, those extra 16 inches of width mean less disturbance. This alone justifies the upgrade for many couples.
- Kids or pets join you regularly. If a toddler climbs in at 3 a.m. or the dog claims the foot of the bed, a king means everyone still has room. On a queen, a 40-lb child somehow takes up 60% of the bed.
- One or both of you is larger. If either partner is broad-shouldered or over 200 lbs, a king provides meaningful extra comfort. The per-person width goes from 30 inches (queen) to 38 inches (king).
- You sleep hot. More mattress surface means more airflow around each person and less body heat overlap. Combined with a cooling mattress, it makes a real difference.
Brantford Bedroom Sizes
Most Brantford homes built before 1980 have master bedrooms around 11' x 12' to 12' x 13', which can accommodate a king with standard furniture. Newer builds in areas like Tutela Heights and the west end often have 13' x 14' or larger master bedrooms. If you're in an older home in Holmedale or West Brant, measure carefully - some master bedrooms are closer to 10' x 11', where a queen is the better fit. Not sure about your room?

Specialty Sizes Worth Considering
Sometimes neither queen nor king is the best answer.
Split King (Two Twin XLs)
Same footprint as a king (76" x 80"), but two independent mattresses. Each person can choose their own firmness. Pair with an adjustable base and each person can raise their head or feet independently. If one of you reads before bed and the other doesn't, this is the solution.
The compromise: there's a small seam down the middle. Most people don't notice it with proper bedding, but it's there.
California King
If you or your partner is over 6'3", a California king adds 4 inches of length (84" vs 80") at the cost of 4 inches of width (72" vs 76"). It's a niche choice, but the right one for taller sleepers whose feet hang off a standard king.
What the Price Difference Actually Looks Like
Let's talk real numbers from our showroom, not theoretical internet prices.
Queen vs. King Price Comparison (2026)
- Entry-level hybrid: Queen ~$599 vs King ~$749 (25% more)
- Mid-range hybrid: Queen ~$899 vs King ~$1,099 (22% more)
- Premium: Queen ~$1,499 vs King ~$1,799 (20% more)
- Luxury (Kingsdown): Queen ~$2,499 vs King ~$2,999 (20% more)
Bedding costs per year: King sheets and duvet covers cost roughly $20-$40 more per set than queen. Over 10 years, that's an extra $200-$400 in bedding costs.
The mattress price difference is typically 20-25%. That's real money, but when you divide by the years you'll use it, the per-night difference between queen and king is often less than $0.05. If the space allows a king and the budget allows it, the extra cost rarely feels significant in hindsight.
Accessories and Frames
The mattress is just one piece. Here's what else changes when you size up.
Bed frame: King frames cost $50-$150 more than queen. The more important consideration is whether your current frame works. If you're upgrading from queen to king, you'll need a new frame.
Mattress protector: Essential regardless of size. King protectors cost $10-$20 more. A small price for protecting a $1,000+ investment.
Pillows: These don't change with mattress size. King pillows (20" x 36") vs standard (20" x 26") is a separate preference. Two standard pillows on a king bed look fine. Two king pillows on a queen bed hang over the edges.
How to Decide Between Queen and King
Step 1: Measure Your Bedroom
Measure the room wall to wall, including closet door clearance and window placement. Subtract 24 inches from each wall where the bed will be positioned (for walking space). If the remaining width accommodates 76 inches (king), great. If not, queen it is.
Step 2: Check Your Hallways and Staircase
Walk the path from your front door to the bedroom. Identify any tight turns, narrow doorways, or staircase landings. A king mattress is 76 inches wide and needs to be maneuvered on its side. If you have concerns, call our delivery team at (519) 770-0001. They'll tell you if it's doable.
Step 3: Consider Your Sleeping Habits
Be honest about how you sleep. If you or your partner spreads out, moves frequently, or runs hot, a king provides meaningful benefits. If you naturally sleep close together and neither person is a restless sleeper, a queen gives you everything you need.
Step 4: Factor in Budget Realistically
Compare the same model in both sizes. If the king version pushes you into a lower-quality mattress to stay on budget, choose a better queen over a cheaper king. The mattress quality matters more than the size. A great queen beats a mediocre king every time.
Step 5: Come Try Both in Person
At our showroom, we have most models in both queen and king. Lie on both with your partner. The feel can differ between sizes because the internal support distribution changes. Ten minutes on each tells you more than any article can.
Frequently Asked Questions
Is a king mattress twice the size of a queen?
No, it's about 27% larger. A queen is 4,800 square inches (60 x 80). A king is 6,080 square inches (76 x 80). The difference is 1,280 square inches, roughly equivalent to adding a crib mattress worth of space alongside a queen. It's meaningful but not dramatic.
Will a king mattress fit through my doorway?
Almost always, yes. A king mattress is maneuvered on its side, making it about 12-14 inches thick going through a 32-inch doorway. The challenge is usually staircase turns, not doorways. Our delivery team handles king deliveries throughout Brantford daily and can assess your home's layout when you order.
What size mattress do most couples buy?
At our Brantford showroom, approximately 60% of couples choose queen and 30% choose king. The remaining 10% go with specialty sizes like split king or California king. Nationally, queen is the most popular size in Canada, accounting for roughly half of all mattress sales.
Can I use queen sheets on a king mattress?
No. Queen sheets are 60" x 80" and king sheets are 76" x 80". Queen sheets won't stretch 16 extra inches and will pull off the corners. Same goes for mattress protectors and fitted sheets. You'll need king-specific bedding. This is an ongoing cost worth factoring into your decision.
Do you carry both queen and king in the same models at your Brantford store?
For most models, yes. Our showroom at 441 1/2 West Street typically has the same mattress in both queen and king so you can compare. Some specialty models may only be on display in one size, but we can order any model in any standard size. Call (519) 770-0001 to confirm availability before visiting.
