Fingernails grow about 3 to 4 millimeters per month, so a full fingernail takes roughly 4 to 6 months to grow out from base to tip. Toenails grow much slower—about 1 millimeter per month—so a full toenail can take 12 to 18 months. Growth speed varies with age, season, overall health, and the individual finger, and you cannot truly exceed your natural rate—only protect nails so they reach their full length.
Whether you are recovering from a broken nail, growing out a short manicure, or just dreaming of longer tips, the same question comes up: how long is this actually going to take? It can feel like watching paint dry—but knowing the real timeline makes the wait far easier (and helps you spot when something is genuinely off).
Here is exactly how long it takes for nails to grow, finger by finger, plus what speeds growth up, what slows it down, and how long to expect for a nail to fully grow back.
Key Takeaways
- Fingernails: ~3–4 mm a month; a full nail in about 4–6 months.
- Toenails: ~1 mm a month; a full nail in about 12–18 months.
- Growth is faster on your dominant hand, in warmer months, and when you’re younger.
- You can’t speed up biology, but preventing breakage means more visible length.
- Very slow growth with other changes is worth a doctor’s check.
How Long Does It Take Nails to Grow?
On average, fingernails grow about 3 to 4 millimeters every month—roughly a tenth of an inch. Because a fingernail is around 1.5 to 2 centimeters from base to tip, it takes about 4 to 6 months for a brand-new nail to grow all the way out and replace the old one completely.
Toenails are the slow cousins, growing only about 1 millimeter a month. A full toenail can take 12 to 18 months to grow out—which is why a stubbed big toe takes so frustratingly long to look normal again.
Nail Growth Rate at a Glance
| Nail type | Growth per month | Time to fully grow out |
|---|---|---|
| Fingernails | ~3–4 mm | ~4–6 months |
| Toenails | ~1 mm | ~12–18 months |
| After full nail loss | Same rates | ~6 months (finger), 12–18 (toe) |
A handy way to picture it: in a single week, a fingernail grows just under a millimeter—so progress is real, just slow enough that a monthly photo shows it best.
How Long to Grow a Nail Back
If you have lost a nail or had to cut one very short, timelines depend on what happened:
- After cutting too short: a few weeks to reach a comfortable length again.
- After a damaged or partly lost fingernail: usually around 4 to 6 months for a full regrowth.
- After a lost toenail: often 12 to 18 months for the full nail.
- After gel or acrylic damage: a full growth cycle to replace the weakened nail with healthy nail.
While you wait, gentle care prevents the new, tender nail from breaking—our pillar guide, how to grow strong, healthy nails, walks through it.
What Affects Nail Growth Speed?
- Age: nails grow faster when you’re younger and gradually slow with age.
- Season: growth is often a little quicker in warmer months.
- Which hand and finger: nails on your dominant hand and longer fingers tend to grow slightly faster.
- Overall health and nutrition: your body builds nails from the nutrients it has.
- Circulation: good blood flow to the nail bed supports growth.
- Pregnancy: many people notice faster nail growth during pregnancy.
- Damage: repeated trauma or illness can temporarily slow a nail down.
Can You Make Nails Grow Faster?
Not really—no product reliably speeds up your biological rate. What you can do is stop nails breaking before they get long, which makes growth finally visible. That distinction is the whole secret, and we cover the exact habits in how to grow your nails faster.
How to Support Healthy Growth
- Hydrate nails and cuticles daily with oil—see our cuticle care guide.
- Wear gloves for cleaning and dishes.
- File gently in one direction and keep a snap-resistant shape.
- Eat enough protein and key nutrients; more in biotin and vitamins for nails.
- Avoid using your nails as tools.
Common Myths About Nail Growth
- “Cutting nails makes them grow faster.” No—trimming does not change the growth rate; it just removes length.
- “Polish stops nails from growing.” Polish does not stop growth; harsh removal can damage the nail, though.
- “A serum can double your speed.” Products support strength and condition, not a faster biological rate.
When Slow Growth Is Worth Checking
Slow-seeming growth is usually just breakage in disguise. But if your nails genuinely grow very little over a long period, or you notice changes in color, shape, thickness, or texture along with it, mention it to a doctor or dermatologist—occasionally very slow growth relates to circulation, thyroid, or nutritional factors that a professional can help with.

How long does it take for a fingernail to fully grow?
About 4 to 6 months for a fingernail to grow out completely from base to tip, at a rate of roughly 3 to 4 millimeters per month.
How long does it take for a toenail to grow back?
Toenails grow about 1 millimeter a month, so a full toenail can take 12 to 18 months to grow back completely.
How much do nails grow in a week?
Fingernails grow just under a millimeter per week on average—real but small, which is why monthly comparisons are easier to see than daily ones.
Do nails grow faster when cut?
No. Cutting or filing does not speed up growth; it only removes length. Growth happens at the base of the nail regardless of trimming.
Why do my nails grow so slowly?
Often it is breakage rather than slow growth—nails snap before they look longer. Age, season, and health also play a role. Persistently very slow growth with other changes is worth a doctor’s check.
The Takeaway
Fingernails grow about 3 to 4 millimeters a month and take roughly 4 to 6 months to fully grow out, while toenails take far longer at 12 to 18 months. You cannot rush the rate, but you can make every millimeter count by protecting your nails from breakage. Snap a monthly photo, keep up your routine, and let time do the rest.
