Perfectly Polished Manicures Begin With These Files

The best nail files can make all the difference when it comes to achieving smooth, strong tips and salon-worthy manicures at home. But with so many shapes, materials, and grit levels (a.k.a. how coarse the file is) on the market, it can be tricky to decide which file is right for your nails. It also depends on your preferred type of manicure (natural, gel, acrylic, or press-on), according to New York City-based nail artist Miss Pop.

As you shop, understanding grit is key: the lower the number, the coarser the nail file will be. Files with 100 to 180 grit are ideal for shaping and shortening gel, acrylic, or press-on nails, while medium grit (around 180 to 220) is better for shaping natural tips—without causing splits or tears. Anything above 220 is considered fine and works well for smoothing edges and buffing the nail surface to a polished finish.

Beyond grit, the material and shape of the file also matter—glass, ceramic, and high-quality emery boards offer unique benefits, from gentle shaping to long-lasting durability. With the right file, keeping your nails in tip-top shape at home can be as satisfying as getting a professional mani. We’ve tried our fair share of the market and tapped experts to find the very best options—scroll through our nail-shaping favorites below.

Why it’s worth it: When you want a salon-quality mani from home, opt for Manuicurist’s Glass Nail Prep Set, which features the Glass Nail File, the Glass Cuticle Pusher, and the Glass Nail Buffer for an all-in-one experience. The file has 180 fine grit, which isn’t too harsh on natural nails, but still has enough strength to refine thick gel or acrylic extensions. It’s super long-lasting, easy to clean, and it works quickly to create your desired nail shape—and cleanly without the frayed edges. It’s so gentle that you can even use it on polished nails without scraping off all your color. Go in with the glass cuticle pusher to gently soften and push back cuticles (which can help nails look longer), plus the glass polisher, which buffs the nail surface smooth for smoother, better, longer-lasting polish application.

“I work hard for my money. (Donna Summer would be proud.) So hard—opening packages, typing furiously, dashing from event to event with heavy bags in my hand—that my nails often break. I need a nail file that can keep up. This one is luxe and has yet to fail me. The glass body shapes and buffs my nails without being overly abrasive. It also lasts forever: I’ve had this file for months, and it works just as well as it did on day one. I keep it in my purse whenever I snag a nail.” —Jesa Marie Calaor, senior beauty editor

Why it’s worth it: Dr. Dana’s Glass Nail File is made from tempered glass with a finely etched surface that shapes nails quickly and precisely. It’s a favorite of Miss Pop because it’s gentle on natural nails and easy to keep clean, since it’s made from non-porous glass that resists bacteria buildup. The smooth glass finish helps prevent snagging and frayed edges, which means less breakage and longer-lasting polish. Unlike traditional emery boards (the type most salons use, which can cause tiny tears and make nails look dull, a glass file seals the nail edge as it shapes, making nails less prone to splitting. It also won’t wear down as easily and stays sharp much longer than an emery board. “Plus, it comes with a durable case, so it travels well in my handbag,” adds Miss Pop.

“I became a glass nail file devotee in 2024 after years of using random cheap-o files that left the edges of my nails frayed, no matter how good my filing technique. I use this product roughly once a week for maintenance and generally any time my nails get overly brittle or break. It works nails down very efficiently, so removing a bit of length from all 10 nails only takes a minute or two, even when I'm really taking my time and making sure to file only in one direction. You might think from its relatively smooth exterior that it doesn't do much compared to a traditional nail file, but it can smooth out an edge in a single swipe and shortens nails so effectively that I have to be careful not to overfile. Even if I do, it never leaves chewed-up edges in its wake. As a lifelong nail-biter, I struggle to keep my nails strong, but having a nail file that creates smooth and clean edges is a big help compared to grittier files, which have historically increased my chances of breaks and splits.” —Nicola Dall’Asen, senior news editor

Why it’s worth it: If you have long, thick nails and you paint them at home, Sally Beauty’s double-sided Rectangular Cushion Nail File is a game-changer. One side is coarse (100 grit) for shaping super-thick nails, while the medium side (180 grit) is better for thinner nails as it keeps your tips shaped to perfection without bending or fraying. For weak or damaged nails—say, after a round of press-ons, acrylics, or gel—you’ll want a finer file with a higher grit (200+), like the Sally Beauty Beauty Secrets White Cushion Nail File, which shapes nails even more gently and helps prevent splitting.

“I come from a long line of women who do much of their nail care at home, and this is the file we all use. It's a sub-$1 tool (ah, the way things used to be!), and it lasts forever. This file shapes like nobody's business and provides so much more control than a mechanical one. I'd recommend this particular file for those who can grow their natural nails long, which means your nails are thick enough to handle this grit, as well as anyone who artfully forms their nails into particular shapes at home. It's washable and good as new after a rinse, and there's just something therapeutic about manually filing your nails into perfect almond shapes.” —Shanna Shipin, senior commerce director

Best for Gel Nails: Tweezerman Professional Nail File

Tweezerman

Professional Nail File

$7

Amazon (3-Pack)

Why it’s worth it: Suitable for any nail need, be it natural, gel, or acrylic, Tweezerman’s Professional Nail File has a coarser 180-grit surface to shape thicker nails and a finer 240-grit surface to smooth edges or use on weaker, thinner nails. If you have gel nails, you can use the coarser side to shortennails and the finer side to refine and smooth edges into your desired shape, whether that’s square, coffin, almond, or round. These files don’t last as long as a glass file, which is why the brand recommends you discard them after three months—but in a pack of three, they’ll last you at least nine months if you file your nails regularly.

Why it’s worth it: The OPI Edge file in 180/400 grit is strong and thin, which Miss Pop says makes it easy to maneuver and perfect the shape of thicker, harder-to-file acrylic nails. The silver, 180-grit side of this file contours and shapes nail enhancements, while the white, 400-grit side smooths and removes imperfections on the nail. Bonus: It’s lightweight and easy to toss in your purse or emergency touch-up kit.

Why it’s worth it: Miss Pop swears by Deborah Lippmann’s nail files for their “perfect grip.” The Smooth Operator takes it a step further with a buffer on the reverse side, making it ideal for laying the perfect foundation for your at-home mani. Start with the gritty side to shape and define, then switch to the buffer to smooth and shine your nails before applying polish. Each side has two sections that are numbered to guide you through the process: one files and gently shapes the nail tip, two buffs ridges, three smooths the nail surface, and four creates a high-shine finish. This file is perfect for days when you want to skip polish altogether and want to go au naturel.

Frequently Asked Questions

What should you look for when shopping for a nail file?

As mentioned, files with 100–180 grit are best for shaping and shortening gel, acrylic, or press-on nails, 180–220 grit works well for shaping natural nails without causing splits or tears, and anything above 220 grit is fine enough for smoothing edges and buffing the nail surface to a polished finish. LA-based nail artist Sarah Chue prefers thin nail boards with a smooth grit (around 150 to 180) and plenty of surface area to handle all nail shapes and sizes. She likes a diamond shape, with a narrow tip and wider middle—it’s versatile enough for every filing need, from refining length and shape to getting super-precise around the tips.

How do you use a nail file?

New York City-based Nail artist Julie Kandalec says that one myth about using a nail file is that it should only be used in one direction. “But, the nail grows straight out, and filing in one direction only works on one half, forcing you to go in the opposite direction for the other half of the nail.”

She explains it with a simple visual: imagine your nail as a clock, where 3 to 9 represents the free edge. Filing from 3 to 6 moves with the natural grain of the nail, but once you pass the center point (6) and continue from 6 to 9 in the same direction, you’re now filing against the grain—this can cause splitting and that unpleasant nails-on-a-chalkboard sensation. Instead, file from each corner toward the center: 3 to 6, then 9 to 6—working corner to center on both sides rather than straight across from 3 to 9.

If you don’t have access to a file, the best press-on nails will cover up what you don’t want anyone seeing.

How we test and review products

When Allure tests a product, our editors look at it from every angle in an effort to best serve you. We scrutinize brand claims and rely on experts who shape their fields to help us vet our picks. We also ask questions about a number of factors: Is it safe for readers who have sensitive skin? Is it on the affordable side or more of a splurge? Is the packaging consciously designed or needlessly wasteful?

For our list of the best nail files, we enlisted the help of multiple editors, writers, contributors, and nail artists to review the products. Testers considered performance across three primary categories: efficacy, wear and longevity, and packaging. For more on what's involved in our reporting, check out our complete reviews process and methodology page.

Our staff and testers

A beauty product is a personal purchase. You might be searching for a face cream to address persistent dryness or a new nail product to add to your Sunday self-care routine; you may simply be browsing around for the latest launches to hit the hair market. No matter what you seek or your individual needs and concerns, Allure wants to ensure that you love anything we recommend in our stories. We believe that having a diverse team of writers and editors—in addition to the wide range of outside testers and industry experts we regularly call upon—is essential to reaching that goal.

After all, can we really say a skin-care product is the "best" for people over 50 if the only testers we've solicited opinions from folks who have yet to hit 30? Can we honestly deem a high-end diffuser worthy of your hard-earned cash if it's never been tested on curls? We're proud that our staff spans a wide range of ages, skin tones, hair textures, genders, and backgrounds, which means that we are able to fairly assess any beauty product that comes into the beauty closet.
