These dimensions are standardised across all Canadian mattress manufacturers. A queen mattress from Restonic, Serta, or any other brand will always measure 60 × 80 inches (152 × 203 cm). Height varies by model: the Restonic ComfortCare is approximately 12 inches tall, while the Revive St Charles reaches 15 inches.

Understanding Mattress Height

Width and length are standard, but height varies by mattress type:

Slim/Low-Profile: 6-8 inches (memory foam, budget options, adjustable bases)

Standard: 9-10 inches (hybrid mattresses, most popular)

Thick/Plush: 11-14 inches (pillow-top designs, luxury mattresses, premium latex)

Higher doesn't always mean better—it depends on comfort needs and bed frame height. Measure your bed frame height and desired total bed height before selecting mattress thickness.

Single Sleeper Sizing

Twin (38x75 inches): Standard single size. Good for kids, teens, space-limited rooms, guest beds. Adequate length for most adults (75 inches = 6'3" with small margin).

Double/Full (54x75 inches): Wider single option. Our complete double mattress size guide covers detailed dimensions. Better for tall people, comfort upgrade from Twin. Still fits in modest bedrooms (10x10 foot minimum).

Pricing Difference: Twin ~$800-1,500 CAD. Double ~$1,000-1,800 CAD. The $200-300 difference often justifies the comfort upgrade for adults.

Lifespan Consideration: If you might eventually share a bed (partner, children), Double is more future-proof than Twin.

Couple Sizing Recommendations

Queen (60x80 inches): 30 inches per person. Adequate space, most popular couple choice. Fits well in standard Canadian bedrooms. Price sweet-spot $1,200-2,500 CAD.

Queen Considerations: Movement transfer noticeable (partner gets up = you feel it). Works for light sleepers only if premium memory foam. Excellent compromise between space and room size.

King (76x80 inches): 38 inches per person. Noticeably more spacious. Better for couples with kids/pets, restless sleepers, or preference for maximum space. Price $1,500-3,500 CAD.

King Challenges: Requires larger bedroom (13x13 feet minimum). Difficult delivery through standard doorways (76 inches vs. 32-36 inch doors—requires angling). Heavier to move (logistics matter).

Test Before Deciding: Lie together on Queen and King for 10+ minutes each. The actual space difference becomes obvious. What looks adequate in a mattress store might feel cramped at home.

Room Size Guidelines

Small Bedroom (10x10 feet): Twin or Double only. King impossible; even Queen is tight for walking space.

Standard Bedroom (12x12 feet): Queen works well. King fits but movement space is minimal.

Large Bedroom (13x14+ feet): King fits comfortably with 3+ feet walking space. Allows bedroom furniture in addition to bed.

Master Bedroom (14x16+ feet): King preferred. Maximum comfort, furniture, and movement space.

Measuring Tip: Account for bedroom doors (swing space), closets, furniture placement, and nightstands. Don't assume full floor space is bed space.

Doorway & Delivery Considerations

Standard Canadian Doorway: 32-36 inches wide. Twin (38 inches wide) requires angling. Double/Queen definitely requires angling. King (76 inches) is extremely difficult or impossible.

Hallway Width: Check hallway width from entry to bedroom. Narrow hallways complicate delivery of larger mattresses.

Staircase Width: If delivery involves stairs, confirm staircase width. Some older Canadian homes have tight staircases.

Delivery Solutions: Professional mattress delivery includes navigation expertise. Mattress Miracle handles challenging deliveries—call 519-770-0001 if your space has tight access points.

Mattress Height Relative to Bed Frame

Standard Bed Frame (24 inches high): Add mattress height (9-10 inches) = total 33-34 inches. Comfortable for sitting and getting out of bed.

Platform Bed (12-18 inches): Lower bed. Add mattress height = total 21-28 inches. Works but can feel low for elderly or mobility-challenged people.

Box Spring Consideration: Traditional box springs add 8-9 inches. Modern foundations are 5-8 inches. Height affects getting in/out ease—matters more with age or mobility limitations.

Design Tip: Aim for 28-34 inches total height (frame + foundation + mattress). Allows comfortable seating without needing to climb in/out.

Price Variations by Size

Twin: $800-1,500 CAD (budget-friendly baseline)

Double: $1,000-1,800 CAD (+$200-300 vs. Twin for same mattress type)

Queen: $1,200-2,500 CAD (+$300-500 vs. Double for same mattress type)

King: $1,500-3,500 CAD (+$400-700 vs. Queen for same mattress type)

Larger sizes use proportionally more materials but cost increases aren't linear. A premium Queen ($2,500) is often excellent value compared to premium King ($3,500) for couple comfort.

Future-Proofing Your Size Choice

Are you likely to share the bed later? Twin is limiting; Double provides upgrade option; Queen/King offer long-term flexibility.

Will you have kids/pets in bed? Plan accordingly. Single sleepers with occasional kids: Queen good. Couples with pets/kids: King preferred.

How long are you keeping this mattress? Oversizing now (choosing larger than minimum need) extends lifespan because comfort doesn't degrade as quickly with space to distribute movement.

Home permanence: Moving to larger home soon? Choose size for future bedroom, not current room.

How to Choose the Right Mattress Size for Your Bedroom

Step 1: Measure Your Bedroom

Measure the length and width of your bedroom, then subtract space for furniture and walking room. A queen mattress (60" × 80") needs at least a 10' × 10' room to feel comfortable. A king (76" × 80") needs at least 12' × 12'. If your room is smaller, stick with a double or full.

Step 2: Consider Who Sleeps in the Bed

A double mattress gives each person 27 inches of width, which most couples find cramped. A queen gives 30 inches per person, which works better for most couples. Singles can sleep comfortably on anything from twin to king, depending on how much space you want and how much your bedroom allows.

Step 3: Account for Sleep Position and Movement

Side sleepers and active sleepers (people who move a lot at night) benefit from extra width. If you sleep sprawled out or change positions frequently, go larger than the minimum. Back sleepers who stay relatively still can get away with smaller sizes without feeling cramped.

Step 4: Check Doorway and Hallway Clearance

A king mattress is 76 inches wide, which won't fit through most standard 32-36 inch doorways without tilting. Measure your doorways, hallways, and stairwells before ordering a large mattress. We've delivered mattresses in Brantford since 1987, and we know which sizes fit through older homes with narrow doorways.

Step 5: Factor in Future Needs

If you're single now but might share the bed later, consider buying queen instead of full. If you have kids who climb into bed with you, extra space matters. If you're buying for a guest room, full or queen works for most visitors without taking up too much space.

Step 6: Test Sizes in Person at Our Showroom

Visit our showroom at 441 1/2 West Street in Brantford to see different mattress sizes side by side. You can lie on a queen, then a king, and feel the actual size difference. This helps more than looking at measurements on a chart. We're open 7 days a week, and you're welcome to test any size.

Step 7: Verify Your Budget Supports the Size

Larger mattresses cost more (a king typically costs $200-400 more than a queen). You'll also need larger sheets, blankets, and potentially a new bed frame. Factor in the total cost, not just the mattress price. Call us at 519-770-0001 to discuss pricing for different sizes.

FAQ: Canadian Mattress Sizing

Q: Can I fit a Queen in my doorway?

A: Possibly with angling. Measure doorway width and hallway width. Most Queens (60 inches) fit diagonally through standard doors (32-36 inches). Professional movers have this figured out.

Q: Is King worth the extra cost and space?

A: For couples, absolutely—if you have room. The comfort difference is noticeable. Test both sizes in-store first.

Q: Can I use a Queen mattress on a Twin frame?

A: No. Mattress dimensions must match frame dimensions exactly. Overhang creates comfort and safety issues.

Q: Do mattress sizes vary by brand?

A: No. Canadian standard sizes are standardized across all manufacturers. A Queen is always 60x80 inches.

Q: What if my room is smaller than recommended?

A: Smaller mattress it is. Twin or Double in compact rooms. Walking space and room aesthetics matter for long-term satisfaction.
