If you’ve ever spent hours at a desk staring at a computer screen, drove cross-country for a family trip, or curled up on a couch watching a movie, you know how tight and sore your neck can feel by the end of it. I’ve been selling memory foam headrests for over seven years now, and the question I get more than any other is: “How do I pick the right one for my neck?” It’s not just about grabbing the most expensive or popular option on the shelf. Your neck size, which is unique to your body, is the biggest factor in making sure a headrest actually works for you—something I learned the hard way in the early days of my business. Memory Foam Headrest
Back when I first launched, I sold a generic one-size-fits-all headrest that I thought worked for everyone. A customer from Seattle wrote to tell me she wore a small neck size and mine pushed too hard, causing more pain than relief. Another guy from Texas, who was 6’4” with a larger neck, said my headrest barely fit around his car seat’s headrest rail. That’s when I realized most brands skip the basics: understanding that neck size isn’t a one-dimensional number. It’s a combination of circumference and depth, and ignoring that leads to headrests that either don’t support your neck correctly or slide around when you need them most.
Today, I’m going to walk you through exactly how to choose a memory foam headrest based on your neck size, with tips I’ve developed from listening to thousands of customers and testing hundreds of products. This isn’t just guesswork—this is based on ergonomic science, which I’ve made sure to integrate into our line of headrests to meet different needs.
First, let’s talk about how to measure your neck size correctly. A lot of people measure wrong, and that’s why they end up with a headrest that doesn’t fit. You don’t want to wrap a tape too tight or too loose. Here’s the right way: stand up straight, relax your shoulders, and keep your head in a neutral position (not tilted forward or back). Take a soft measuring tape and wrap it around the base of your neck, right where your neck meets your shoulders. That’s the circumference. If you don’t have a tape, use a piece of string, mark where it meets, and then measure it against a ruler. For most adults, neck sizes range from 12 inches (30 cm) to 18 inches (46 cm), but this varies a lot between people. A 5’2” woman might have a 13-inch neck, while a 6’3” man could have a 17-inch neck. The key is accuracy—if your measurement is even half an inch off, your headrest won’t fit right.
Now, why does your neck size matter for a memory foam headrest? Memory foam works best when it conforms to your unique shape, not the other way around. A headrest that’s too small will compress too much in the wrong spots, leaving gaps where your neck needs support. A headrest that’s too big will be floppy, so it won’t hold your head and neck in the neutral position your spine needs. Neutral position is important because when your head tilts forward (like when typing or looking down at a phone), it adds extra stress to your neck muscles. A good headrest should cradle the curve of your neck, not push it forward or let it loll to the side when you’re resting.
Let’s break this down by common neck size groups, so you can find what fits you best.
Small neck size (12–14 inches / 30–35 cm): This is common for people who are petite, women with smaller frames, or teens. If you fall into this group, you need a headrest that’s compact enough to fit closely around your neck without being bulky. Many one-size-fits-all headrests are too wide for small necks, so they end up sitting on the edges of your neck instead of supporting it. The memory foam in these should be medium firm—not too soft that it collapses, but soft enough to contour to a smaller frame. I’d also recommend a headrest with adjustable straps that don’t have too much extra length, because loose straps will make the headrest slide around. A common mistake here is buying a larger headrest to “grow into”—it will never fit right, and you’ll just waste money.
Medium neck size (14–16 inches / 35–40 cm): This is the most common size, fitting most average-sized adults. If you’re a 5’5” to 5’10” person, you’re probably in this range. For medium necks, you have the most options, but the key is to balance support and comfort. Look for a memory foam headrest with a density of 3–4 pounds per cubic foot. This density is firm enough to support the neck, but soft enough to adapt to the curve. Some brands make “universal” headrests that work for medium sizes, but make sure the depth of the headrest (how far it extends from the mounting point) is between 3–4 inches. If it’s too shallow, it won’t cover the full length of your neck; too deep, and it will push your head forward.
Large neck size (16–18 inches / 40–46 cm): People with larger necks, often taller men or people with broader frames, need a headrest that has extra width and support. Generic headrests here usually feel too narrow, so they don’t hold the sides of your neck, leading to side-to-side tilt. For large necks, look for a headrest that’s at least 5 inches deep, with a memory foam density of 4–5 pounds per cubic foot. This firmer foam won’t flatten out under the weight of a larger head, and the extra width will cradle both sides of your neck. I’ve seen a lot of customers with large necks buy smaller headrests because they think they “should,” but that’s a surefire way to get neck pain. It’s better to spend a little more on a headrest made for larger sizes than to deal with the discomfort.
Now, it’s not just about neck circumference—you also need to consider neck depth. Some people have a slim neck (circumference 14 inches, but depth only 2.5 inches), while others have a stocky neck (same circumference, depth 4 inches). If you ignore depth, you might get a headrest that’s too shallow for a deep neck, leaving the top of your neck unsupported, or too deep for a slim neck, pushing against the front of your throat. That’s why measuring both circumference and depth is important.
Another thing to keep in mind: where you’re using the headrest. If you’re buying it for your car, you need to make sure it fits your car’s headrest rail. Most car headrests have rails that are 4–6 inches apart, so a headrest with adjustable mounting bars will work for any car, regardless of neck size. If you’re buying it for your desk chair, you can opt for a strap-on style, but make sure the strap is adjustable to fit different neck sizes. For travel, a compact headrest that’s made for small to medium necks is better, because large headrests are too bulky to fit in a carry-on.
Memory foam quality matters too, and it’s tied to how well it works for your neck size. Low-quality memory foam (density less than 3 pounds per cubic foot) will wear out quickly, flattening after a few months. That means it won’t support your neck anymore, even if it’s the right size for you. High-quality memory foam (4–5 pounds per cubic foot) retains its shape for 3–5 years, adapting to your neck size every time you use it. We use CertiPUR-US certified foam in our headrests, which means it’s free of harmful chemicals, so it’s safe to use for long periods—especially important if you use your headrest at work every day.
I also get asked a lot about whether you need a contoured headrest versus a flat one. Contoured headrests have a curve in the middle, designed to fit the natural C-shape of your neck. For most people, this is better, but if you have a smaller neck, a contoured headrest might be too curved, pressing on the sides of your neck. If that’s the case, a flat, medium-density headrest will work better. For larger necks, a contoured headrest will cradle the sides, reducing side-to-side movement, which is exactly what you need.
Let me share a customer story that illustrates this. Last year, a customer from Dallas emailed me saying he had a 17-inch neck and had tried three different headrests, all of which left his neck sore after a 2-hour drive. He ordered our large-sized headrest with 4-pound memory foam. A week later, he wrote back saying, “This is the first time I’ve driven from Dallas to Austin without stopping to stretch my neck. It fits perfectly—supports the curve of my neck without pushing too hard.” That’s the magic of matching the headrest to your neck size.
Now, let’s cover some common mistakes people make when choosing a headrest based on neck size. The first is assuming that neck size is the same as height. I’ve seen a 5’10” woman with a 13-inch neck and a 5’5” man with a 17-inch neck—height doesn’t always correlate. The second mistake is forgetting to measure while relaxed. If you stand up with your head tilted forward, your neck circumference will be smaller, leading you to buy a headrest that’s too big. The third mistake is skimping on quality to save money. A $10 headrest will use low-density foam that flattens in a month, so even if it’s the right size, it won’t last. Our headrests are priced higher, but they’re built to last, so you get your money’s worth.
If you’re still unsure what size is right for you, here’s a quick checklist:
- Measure your neck circumference correctly (relaxed, base of neck).
- Measure your neck depth (from the base of your neck to the front of your throat) to get a full picture.
- Decide where you’ll use the headrest (car, desk, travel) to narrow down mounting options.
- Match your size to the headrest’s sizing: small (12–14”), medium (14–16”), large (16–18”).
- Check the foam density: 3–4 lb for medium necks, 4–5 lb for large necks, medium firm for small necks.
At the end of the day, a memory foam headrest isn’t just a luxury item—it’s an investment in your neck health. Poor neck support can lead to chronic pain, headaches, and even posture issues over time. That’s why we designed our line to cater to all neck sizes, because we’ve seen how a good headrest can change someone’s daily comfort.
