Choosing a mattress size can feel a lot like shopping for a car. Let’s be honest: it’s a big investment that can impact you for years to come. When it comes to mattresses, size actually does matter. The "right" mattress size isn't just the one that fits through your door (though that's definitely important). It's about how you actually sleep and who you're sharing your sleep space with.

Whether you're setting up your first apartment, finally upgrading from that college futon, making room for a partner who steals covers like it's their job or dealing with a dog who somehow takes up 75% of the bed (we see you, pet parents), getting the right mattress size matters. And hey, we're here to help you figure it all out without the industry jargon or pushy sales tactics. In this blog, we’re breaking down everything from Twin to California King to help you figure out what actually makes sense for your life.

Before we dive into the nitty-gritty dimensions, let's talk about why this decision is kinda a big deal. Spoiler alert: it's not just about having somewhere to crash at night, and despite the mattress shopping myth that bigger is always better, that's not necessarily the case. You spend roughly a third of your life on your mattress. That's more time than you'll spend in your car, in the shower or even binge-watching Netflix (okay, maybe not that last one). So, getting the size right is basically an investment in your daily happiness and long-term health.

The wrong mattress size can mess with everything from your sleep quality to your relationship dynamics to your mental health and immune system. Here's what you need to consider: your sleep quality and room set up (we all need room to move without playing mattress Tetris), your actual room dimensions (PSA: that California King needs to fit through your doorway AND leave walking space) and your real lifestyle factors. Do you sleep solo but sprawl like a starfish? Got a partner who's basically a human furnace? Maybe a few dogs who think they're lap-sized but weigh 80 pounds? Your mattress should work for your actual life. Period.

Alright, let's break down your options from smallest to largest. Each size has its sweet spot, and we'll help you figure out which one's calling your name.

The classic single bed – and still a solid choice for certain situations! Twin mattresses work great for kids' rooms, bunk beds or small guest rooms where space is at a premium.

If you're furnishing a child's room, a Twin gives them plenty of space to grow while keeping the room functional for play and activities. For adults, though, a Twin can feel pretty restrictive unless you're working with very limited space.

Best for: Kids, bunk beds, small guest rooms or studio apartments where every square foot counts.

Think of Twin XL as the Twin's taller sibling. With an extra 5 inches of length, it's perfect for taller teens or college students who need single-bed dimensions but don't wanna feel like their feet are hanging off the end.

Most college dorms use Twin XL, so if you're shopping for a student, this is likely what you'll need. The extra length makes a real difference for anyone over 5'8".

Best for: Teens, college students, taller solo sleepers or guest rooms for tall visitors.

The Full (sometimes called Double) offers more width than a Twin but the same length. It's a step up for solo sleepers who like to spread out, but it can feel pretty cozy for two people.

We'll be honest – while a Full can technically fit two adults, you're looking at about 27 inches of space per person. That's narrower than a Twin! If you're planning to share regularly, you might consider sizing up.

Best for: Solo adults who want more space than a Twin, teens transitioning to adult beds or guest rooms where couples might occasionally stay.

The Queen is the Goldilocks of mattress sizes – not too big, not too small, just right for most people. It's the most popular size for couples, and for good reason. You get 30 inches of space per person, plus it fits well in most bedrooms without overwhelming the space.

Queen mattresses also hit that sweet spot for bedding availability and price. You'll find tons of organic sheet options, and the size works well whether you're sleeping solo with room to sprawl or sharing with a partner.

Best for: Couples, solo sleepers who love extra space or anyone who wants the most versatile size option.

Now we're talking serious space. A King gives you the same length as a Queen but adds 16 inches of width – that's like having two Twin XLs side by side! If you're sharing with a partner, kids who like to visit or pets who think they own the bed, a King can be a game-changer.

The trade-off? You'll need a larger bedroom to make it work, and King-size organic bedding can be a bit pricier. But if you've got the space and budget, the extra room can seriously upgrade your sleep quality.

Best for: Couples who want maximum space, families who co-sleep, pet owners or anyone who just loves having room to spread out.

The California King is for the tall folks out there. It's actually 4 inches narrower than a standard King but 4 inches longer. If you're over 6 feet tall and find yourself wishing for more legroom, the California King might be your answer.

Just keep in mind that Cal King bedding can be harder to find and more expensive than standard sizes. But if you need that extra length, it's totally worth it for better sleep!

Best for: Tall sleepers (6'2" and up), couples where one or both partners are tall or anyone who prioritizes legroom over width.

Look, we get it. When you're mattress shopping, it's tempting to go with the "bigger is better" mentality. But trust us – we've seen plenty of people end up with buyer's remorse because they didn't think through the practical stuff first. 

Here are the important things to consider before finalizing your decision:

• Bedroom size and layout: Measure your room before you fall in love with a mattress size. You'll want at least 2-3 feet of walking space around the bed and consider how the size will affect your ability to open doors, drawers and closets.
• Who's sleeping on it? (now and in the future): Think beyond just tonight. Are you single now but hoping that changes? Do you have kids who might want to join you for weekend morning cartoons? Planning ahead can save you from needing to upgrade in a couple of years.
• Lifestyle changes: Life happens, and your sleep needs might change. Maybe you're moving to a bigger place next year, or perhaps you're planning to start a family. A slightly larger mattress now might save you the hassle and expense of upgrading later.
• Budget and bedding compatibility: Larger mattresses cost more upfront, and you'll also pay more for organic sheets, comforters, toppers and other bedding throughout the life of your mattress. Factor in these ongoing costs when you're deciding. Also think about what bedding you already own and may want to keep.

There’s no one-size-fits-all answer to mattress sizing. The "right" size depends on your space, your sleep style, your budget and your life plans. What we can say is this – investing in a mattress that truly fits your needs is one of the most impactful things you can do for your daily wellbeing. When you sleep better, everything else gets better, too.

And when you choose an organic mattress in the right size, you're not just investing in your own rest but supporting more sustainable manufacturing practices and healthier sleep environments for everyone. That's the kind of choice that feels good in more ways than one! Now ... ready to find your perfect fit?
