A full mattress measures 54 inches wide by 75 inches long (137 × 190 cm). A queen mattress measures 60 inches wide by 80 inches long (152 × 203 cm). That 6-inch width difference and 5-inch length difference matter more than most people expect — especially for couples, taller sleepers, or anyone buying for a master bedroom. If you have the room, the queen is almost always the better long-term choice.
Who this guide is for: Anyone deciding between a full and queen mattress — whether you're furnishing a guest room, setting up a studio apartment, helping a teen pick their first "adult" bed, or shopping for a master bedroom and weighing whether the size upgrade is worth it.
This guide is written by a Sleep Expert with hands-on experience helping customers find the right mattress fit. Dimension data reflects industry-standard U.S. mattress sizing.
---A full mattress — also commonly called a double mattress — measures 54 inches wide by 75 inches long, or approximately 137 cm × 190 cm in metric.
The "double" label dates back to when a full was considered the double-wide upgrade from a twin (38" × 75"). Despite the name, a full isn't generous for two adults by modern standards. It does give a solo sleeper significantly more space than a twin — 16 extra inches of width — which is why it remains a popular choice for teens transitioning out of childhood beds and for guest rooms that need to accommodate occasional single-night visitors.
At 75 inches long, a full is also on the shorter side. Anyone 6 feet tall or above (72 inches) will have only 3 inches of headroom — and that's before you factor in a pillow. If you're above 6'1", a full almost certainly isn't long enough for comfortable sleep.

Did You Know? The terms "full" and "double" refer to the exact same mattress size. The name "double" originated because it was literally double the width of a twin (38" × 2 = 76" — close enough given historical mattress tolerances). Today, "full" is the more commonly used industry term, but you'll still see "double" on bedding packaging.
Queen mattress dimensions are 60 inches wide by 80 inches long, or 152 cm × 203 cm in metric. The queen is the most popular mattress size in the United States, and for good reason: it balances sleeping space with practicality for most bedrooms.
The 80-inch length is a major upgrade for taller sleepers. Someone who is 6'3" (75 inches) still has 5 inches of clearance — enough for a comfortable night without feet hanging off the edge. That extra 5 inches of length over a full can make a meaningful difference for anyone over 5'10".
For couples, the queen provides 30 inches of personal space per person — not luxurious, but workable, especially if neither partner is a sprawling sleeper. If either person runs warm, moves a lot at night, or you have a dog or cat that shares the bed, that extra width becomes even more valuable.
You can explore queen size mattresses across a range of brands, feels, and price points.
Did You Know? The queen mattress didn't exist until the 1950s. Before that, the full (double) was the standard "large" bed for couples. The queen was introduced as American homes grew larger and consumers began expecting more personal space in shared beds.

Six inches might not sound like a big deal, but in bed it translates directly to whether one person feels cramped. A queen's 60-inch width gives each co-sleeper 30 inches — not spacious, but livable. A full's 54-inch width leaves each person 27 inches, about the same width as a twin bed. If you've ever slept on a twin as an adult, you know that 27 inches is tight.
Solo sleepers, however, get the full 54 inches to themselves on a full — which is plenty of room for one person who doesn't move much at night.
The queen's 80-inch length versus the full's 75 inches is where height becomes a real factor. If you're 5'10" or under, either size works fine. At 6'0", a full gives you 3 inches of clearance — enough, but you'll want your pillow to compress a bit. At 6'2" or above, the full is genuinely too short for comfortable sleep, and a queen becomes the practical minimum.
"For anyone over 6 feet tall, the queen's extra 5 inches of length isn't a luxury — it's the difference between sleeping comfortably and waking up with your feet off the edge."
Interior designers and sleep specialists generally recommend the following minimum room dimensions:
That said, these are minimums — not ideals. A 12×14 or larger room is far more comfortable for a queen. If your bedroom is under 10×12, you may want to consider whether a full is genuinely a better fit, or whether rearranging furniture could open up space. See our full mattress sizes guide for room size recommendations across all bed sizes.
Most standard full and queen mattresses are built to support 250–500 lbs, depending on the construction and brand. Queens aren't inherently rated for higher weight just because they're larger — weight capacity depends on the mattress's internal construction, coil gauge, foam density, and edge support. If weight capacity is a concern, check the manufacturer's specific rating for any mattress you're considering, regardless of size.
Full-size sheets are easy to find, but queen sheets are even more ubiquitous — they're stocked by virtually every bedding brand at every price point. Queen bedding also tends to be sold in more styles and patterns, simply because it's the most popular size. If you're particular about your bedding selection, the queen wins on variety.
---A full mattress is the right call in several specific situations:
If you're shopping for a full, browse the full size mattress collection to compare options.
---A queen is the better choice for a wider range of sleepers and situations:
Try Before You Buy — Dimensions on paper don't always match how a mattress feels in person. Visit one of our Southern California showrooms to lie down on both a full and a queen side by side. Most customers immediately feel the difference — and it's often what makes the decision easy.
Across most mattress brands and categories, a queen costs roughly $100–$300 more than the same model in full size. At the entry level (under $600), the difference might be $75–$150. At the mid-range ($800–$1,500), expect a $150–$250 gap. At the premium tier, the difference can be $300 or more.
That price gap also extends to accessories:
Over the 8–10 year life of a quality mattress, that initial $200 upgrade to a queen often averages out to less than $25 per year — a consideration worth factoring in if comfort and longevity matter to you. For reference, you can read our guide on how to choose a mattress for more on evaluating long-term value.
Did You Know? The queen is the best-selling mattress size in the United States. That high demand means more manufacturers compete for your business at the queen size level — which generally keeps pricing competitive and gives you more options at every budget.
Technically, yes. In practice, it depends on the people and the expectation.
A full's 54-inch width gives two adults 27 inches each — roughly the width of a twin bed per person. For reference, a twin is 38 inches wide for one person, so a full gives two adults noticeably less personal space than a twin gives one. Two adults sleeping together on a full will be physically close, with limited room to shift positions independently without affecting the other person.
It can work reasonably well if:
It's likely to feel cramped if:
If two adults are sharing a bed regularly, a queen is generally the recommended minimum. For couples who want even more space, exploring king size mattresses or even a California king may be worth considering.
---Yes — "double" and "full" refer to the exact same mattress size: 54 inches wide by 75 inches long. The terms are interchangeable. "Double" is the older term, historically referring to being double the width of a twin. "Full" is now the more common industry designation, but you'll still see "double" on some bedding packaging and older bed frames.
A standard queen mattress is 60 inches wide by 80 inches long (152 cm × 203 cm). This is the most common mattress size in the United States. Note that "split queen" mattresses (two 30"×80" pieces) and "Olympic queen" (66"×80") exist but are niche sizes — when someone says "queen," they almost always mean the standard 60×80.
A full mattress (also called a double) is 54 inches wide by 75 inches long (137 cm × 190 cm). It is 16 inches wider than a twin but 6 inches narrower and 5 inches shorter than a queen.
A queen is 6 inches wider (60" vs 54") and 5 inches longer (80" vs 75") than a full. In total surface area, a queen offers about 750 more square inches of sleep surface — roughly an 18% increase over a full.
No. Full and queen sheets are not interchangeable. Full sheets will be too narrow and too short for a queen mattress — they won't tuck properly and will likely pop off during the night. Always use queen-specific bedding on a queen mattress.
The minimum recommended room size for a queen bed is 10 × 14 feet. This allows approximately 2 feet of walkway on the sides and at the foot of the bed. For a more comfortable layout with room for a dresser or nightstands, a 12×14 ft or larger room is preferable. A full mattress fits comfortably in a 10 × 12 ft minimum room.
Either can work, but it depends on the teen's height and how long the mattress needs to last. A full is sufficient for most teens under 5'10" and fits well in smaller bedrooms. However, if the teen is already tall or you want the mattress to last through college and early adulthood, a queen is the better long-term investment — and it avoids an upgrade purchase in a few years.
For couples or taller sleepers, the extra cost is almost always worth it. For solo sleepers under 6 feet in a smaller room on a tighter budget, a full may genuinely be the better choice. The value depends on your specific situation — height, sleeping arrangements, bedroom size, and how long you plan to keep the mattress.
