Choosing the right bed dimensions can make or break your sleep quality. Whether you’re 5’10” or 6’4″, single or sharing with a partner, understanding exact mattress measurements helps you avoid costly mistakes.

This bed dimensions chart covers every standard size in inches, feet, and centimeters. You’ll learn which bed fits your height, room size, and sleeping style—plus get answers to the most common sizing questions.

The Twin mattress measures 38 inches wide by 75 inches long. It’s the narrowest standard size available in the US market.

Twin XL adds 5 extra inches of length, measuring 38 × 80 inches. This makes it perfect for anyone over 6 feet tall who sleeps alone.

Room size requirements: A Twin needs at least 7 × 10 feet of floor space. Twin XL works in the same footprint but gives taller sleepers crucial legroom.

The Full bed measures 54 inches wide and 75 inches long. Some retailers still call it a “Double bed,” though this name causes confusion since it doesn’t comfortably fit two adults.

Can a 5’10” person fit on a full size bed? Yes, absolutely. At 75 inches (6 feet 3 inches), the Full provides 5 extra inches of length beyond your height. You’ll have comfortable headroom and footroom.

The Queen bed measures 60 inches wide by 80 inches long. It’s America’s #1 selling mattress size for good reason—it balances space, price, and practicality.

Each partner gets 30 inches of personal width on a Queen. That’s the same as a crib mattress. It works if you’re both average-sized and don’t move much during sleep.

Room size minimum is 10 × 10 feet. Ideally, you want 12 × 12 feet to fit nightstands and leave comfortable walking paths.

Queen mattresses cost 20-30% less than Kings on average. Sheets, frames, and accessories are also cheaper and easier to find. Nearly every bedding brand makes Queen-sized products.

The Standard King measures 76 inches wide by 80 inches long. That’s exactly the width of two Twin XL mattresses side by side.

California King measures 72 inches wide by 84 inches long. It trades 4 inches of width for 4 inches of extra length—making it ideal for tall sleepers in narrow bedrooms.

European sizing differs significantly. A European Double is 140 × 200 cm (55 × 79 inches). Their Queen equivalent measures 160 × 200 cm (63 × 79 inches)—3 inches wider than US Queens but 1 inch shorter.

UK Super King beds measure 6 feet by 6 feet 6 inches (180 × 200 cm). That’s 72 × 78 inches—close to a US California King but 6 inches shorter.

Asian markets use unique dimensions. Japanese Single beds are 39 × 75 inches (nearly identical to US Twins). Japanese Doubles measure 55 × 75 inches—1 inch wider than US Fulls.

Australian bed sizes closely match US standards but use metric measurements exclusively. Their Queen is 153 × 203 cm (virtually identical to US Queens at 152 × 203.5 cm).

Canadian mattresses use the exact same dimensions as US beds. A Canadian Queen is identical to an American Queen—60 × 80 inches.

Olympic Queen measures 66 × 80 inches, providing 6 extra inches of width compared to standard Queens. It’s perfect for couples who want more space but can’t fit a King in their bedroom.

Split King consists of two Twin XL mattresses (38 × 80 inches each) placed side-by-side. Total dimensions are 76 × 80 inches—identical to a standard King. This setup allows couples to choose different firmness levels and works with split adjustable bases.

RV and camper bed sizes vary dramatically by manufacturer. Common RV dimensions include RV Queen (60 × 75 inches), RV King (72 × 80 inches), and RV Bunk (28 × 75 inches). Always measure your RV mattress space before ordering.

Alaskan King measures 108 × 108 inches—that’s 9 feet by 9 feet. It’s the largest commercially available mattress in the world, offering 81 square feet of sleeping surface.

Texas King measures 80 × 98 inches (6.67 × 8.17 feet). The extra length accommodates extremely tall sleepers or families who co-sleep with multiple children.

Wyoming King measures 84 × 84 inches (7 × 7 feet). This square shape provides equal space in all directions—ideal for active sleepers who rotate during the night.

FAQs

What are the dimensions of bed sizes?

Twin: 38 × 75 inches. Twin XL: 38 × 80 inches. Full/Double: 54 × 75 inches. Queen: 60 × 80 inches. King: 76 × 80 inches. California King: 72 × 84 inches. These are the six standard mattress sizes in the United States.

Can a 5’10” person fit on a full size bed?

Yes, easily. At 5’10” (70 inches), you’re 5 inches shorter than the 75-inch mattress length. This gives you comfortable head and foot clearance. However, you’ll only have 54 inches of width—fine for solo sleeping but cramped for couples.

What bed is 6 ft by 5 ft?

No standard US bed dimensions match 6 feet by 5 feet exactly (72 × 60 inches). The closest standard size is a Queen at 60 × 80 inches (5 × 6.67 feet)—same width but longer. For an exact 6 × 5-foot mattress, you’d need a custom order.

What are the dimensions of different types of beds?

Crib: 28 × 52 inches. Toddler: 28 × 52 inches. Twin: 38 × 75 inches. Twin XL: 38 × 80 inches. Full: 54 × 75 inches. Queen: 60 × 80 inches. King: 76 × 80 inches. California King: 72 × 84 inches. Specialty sizes range from 66 inches (Olympic Queen) to 108 inches (Alaskan King).

Are all double beds 4ft 6?

In the UK, yes—Double beds measure 4 feet 6 inches wide (135 cm). In the US, Full/Double beds measure 54 inches wide, which equals 4 feet 6 inches. However, lengths differ: UK Doubles are 6’3″ (190 cm) while US Fulls are 75 inches (190.5 cm). The names match but international standards vary slightly.

Can a 6’4″ person fit on a full size bed?

No, not comfortably. At 6’4″ (76 inches), you’re 1 inch taller than the 75-inch mattress. Your feet will hang off the edge. Anyone over 6’2″ needs an 80-inch bed minimum—Queen, King, California King, or Twin XL all work.

How do I measure the size of my bed?

Remove all sheets and bedding first. Measure width from left edge to right edge of the mattress—not the frame. Then measure length from head to foot down the center. Use a metal tape measure for accuracy. Record both measurements in inches. Compare your numbers to standard sizes: 60 × 80 is Queen, 76 × 80 is King, etc.

Are hotel king beds smaller?

Most US hotels use standard King beds (76 × 80 inches)—the same size you’d buy retail. However, European hotels often use UK Super Kings (72 × 78 inches), which are 4 inches narrower and 2 inches shorter than American Kings. Luxury hotels occasionally use custom sizes, but this is rare.

Conclusion

The right bed dimensions depend on three factors: your height, who shares the bed, and your room size. Anyone under 6’2″ fits standard 75-inch or 80-inch lengths. Couples need 60+ inches of width. Your bedroom should be 5-6 feet wider than your mattress.

Queens work for most couples on a budget. Kings suit families and restless sleepers. California Kings serve tall individuals in narrow rooms. Always measure your space before buying.
