Whether you’re looking to shape, trim, or smooth the surface of your natural nails, choosing the correct nail file can make all the difference in achieving the results you want.
Choosing the right nail file isn’t just a matter of personal preference; it directly impacts the appearance of your nails. The wrong choice can lead to breakage, splitting, and damage, while the right one can help you achieve beautiful, well-groomed nails.
In this guide, we’ll:
- walk you through the details of selecting the perfect nail file for your natural nails
- cover everything from understanding grit sizes to exploring the various types of nail files available
Understanding Nail File Grit
When it comes to selecting the right nail file for natural nails, understanding the concept of “grit” is paramount. Grit refers to the level of abrasiveness on the surface of the nail file, and it plays a crucial role in achieving the desired nail finish. Let’s explore this fundamental aspect of nail file selection:
What is Grit?
Grit essentially refers to the coarseness or fineness of the abrasive material on the surface of the nail file. It’s typically measured in grit numbers, and the higher the number, the finer the grit. Here’s a quick breakdown:
- Low Grit (e.g., 80-100): These are very coarse and suitable for heavy-duty nail shaping, like reducing the length of acrylic or artificial nails. Coarse grit files (80-100) are best used for shaping and shortening your nails. However, they may be too abrasive for natural nails and are better suited for artificial nail materials like acrylic or gel.
- Medium Grit (e.g., 150-180): These are versatile and work well for both shaping and smoothing natural nails. Medium grit files (150-180) are all-rounders, suitable for shaping and smoothing the edges of natural nails. They’re ideal for removing any minor imperfections without causing excessive damage.
- High Grit (e.g., 240-600+): These are fine grit files, ideal for refining and finishing your natural nails. Fine grit files are the finishing touch. They’re perfect for refining the nail’s surface, removing any remaining roughness, and leaving your natural nails with a polished look.
Types of Nail Files
Now that you’ve gained an understanding of nail file grit, it’s time to explore the various types of nail files available. Each type has its own set of characteristics, advantages, and disadvantages. Let’s take a closer look:
A. Emery Boards
Emery boards are perhaps the most common and widely recognized type of nail file. They consist of a cardboard or wooden core with an abrasive surface, typically made from emery or aluminum oxide.

Characteristics and Uses
- Affordable and readily available: Emery boards are budget-friendly and easy to find in most drugstores and beauty supply shops.
- Double-sided: They often come with different grits on each side, providing versatility for shaping and smoothing.
- Portable: Compact and lightweight, making them ideal for on-the-go nail touch-ups.
Pros and Cons for Natural Nails
- Pros: Emery boards are suitable for shaping natural nails and making minor adjustments. They work well for people who prefer a soft, more flexible file.
- Cons: The abrasive surface can wear out relatively quickly, and it may not be as durable as some other options. Coarse-grit emery boards can be harsh on natural nails if used aggressively.
B. Glass Nail Files
Glass nail files are gaining popularity for their smooth, gentle, and long-lasting performance. They are typically made of tempered glass and feature a finely etched surface.

Characteristics and Uses
- Durable and long-lasting: Glass files can withstand a lot of use without degrading.
- Gentle on nails: They provide a smooth, snag-free filing experience that’s less likely to cause splintering.
- Easy to clean: Glass files are non-porous, making them hygienic and easy to clean.
Pros and Cons for Natural Nails
- Pros: Glass files are gentle on natural nails and can help prevent chipping and peeling. They’re excellent for fine-tuning and achieving a polished finish.
- Cons: They tend to be pricier than some other options, and they can be brittle, so care is needed to avoid breakage.
C. Metal Nail Files
Metal nail files are often made of stainless steel and feature a finely grained surface.

Characteristics and Uses
- Durable and long-lasting: Metal files are sturdy and don’t wear out quickly.
- Effective for heavy-duty filing: They’re well-suited for thick or artificial nails.
- Easy to clean: Like glass files, metal files are non-porous and easy to sanitize.
Pros and Cons for Natural Nails
- Pros: Metal files are effective for shaping and trimming natural nails and can last a long time.
- Cons: They can be quite abrasive, and when used incorrectly, they may cause damage to natural nails.
D. Diamond Nail Files
Diamond nail files feature a surface embedded with fine diamond particles and are known for their precision.
Characteristics and Uses
- Highly durable: Diamond files can last a long time without losing effectiveness.
- Great precision: They’re excellent for detailed work and achieving a polished finish.
- Hygienic and easy to clean: Like glass and metal files, diamond files are non-porous and easy to maintain.
Pros and Cons for Natural Nails
- Pros: Diamond files are gentle on natural nails and provide excellent precision. They’re perfect for maintaining a polished look.
- Cons: They can be relatively expensive, and the abrasive surface may not be ideal for heavy-duty filing.
Choosing the right type of nail file depends on your specific nail care needs and preferences. Whether you opt for the affordability of emery boards, the gentleness of glass, the durability of metal, or the precision of diamond, each type has its own advantages to offer.
Shape and Size Considerations
Now that you have a grasp of grit and the types of nail files available, it’s time to delve into shape and size considerations. The shape and size of your nail file play a significant role in achieving your desired nail shape and style. Let’s explore these aspects:
Different Nail File Shapes
Nail files come in various shapes, and choosing the right one can help you achieve your preferred nail shape:
- Flat Files: These are the most common and versatile nail file shapes. They work well for basic nail shaping and edge smoothing.
- Curved Files: Curved nail files have a slight arc, making them suitable for following the natural curvature of your nails. They’re excellent for achieving a more rounded or almond-shaped nail.
- Tapered Files: Tapered nail files are narrower at one end and wider at the other. They’re great for creating a pointed or coffin-shaped nail.
By considering the shape and size of your nail file, you can customize your nail care routine to achieve the perfect nail shape that complements your style.
Choosing the Best Nail File for Your Natural Nails
Now that you’ve explored the world of nail files, from understanding grit to selecting the right type, shape, size, and additional features, it’s time to make your choice. Selecting the best nail file for your natural nails is a personalized decision, influenced by your unique needs and preferences.
The choice of grit depends on your specific needs and the current condition of your natural nails. If you’re aiming for a complete nail makeover or dealing with extensive reshaping, start with a coarser grit and progressively move to finer grits to achieve that sleek finish.
For routine maintenance and fine-tuning, a medium or fine-grit file is your best bet. They allow for precise control without over-exfoliating your natural nails.
Summary of Key Factors to Consider
- Grit: Determine the appropriate grit based on your nail care needs. Coarse for shaping, medium for general maintenance, and fine for finishing and polishing.
- Type: Choose the type of nail file that aligns with your preferences. Emery boards, glass, metal, or diamond files each have their unique characteristics.
- Shape and Size: Consider the shape and size of the nail file that complements your desired nail shape and the portability you require.
- Special Features: If you prefer added convenience, select a nail file with special features like buffers, polishers, or ergonomic handles.
- Coatings: Decide whether a coated nail file suits your longevity and efficiency preferences.
- Technique: Master the correct nail filing technique to ensure precision and avoid common mistakes that could damage your natural nails.
- Cuticle Care: Don’t forget to maintain the health of your cuticles with regular moisturizing.
- Hygiene and Maintenance: Keep your nail file clean and sanitized to ensure its longevity and the health of your nails.
