How to Cut Toenails Properly (Nakhun): How Often, Ingrown Nails
“Raat ko nakhun mat kaato,” elders used to say, and there was sense in it once: blades were sharp and lamps were dim. The rest is simpler. To cut toenails properly, trim them straight across after a bath, leave them level with the tip of the toe, and do it every 3 to 6 weeks; fingernails need a trim every 1 to 2 weeks.
This guide covers how often, how short, which clippers, how to help an older parent, and how ingrown toenails start and what to do in the first few days, while baby nails, which need different tools and a different method, are left for another day.
Quick facts
- Fingernails: every 1 to 2 weeks. They grow roughly 3 mm a month.
- Toenails: every 3 to 6 weeks. They grow about a third as fast.
- Shape: toenails straight across; fingernails can follow the fingertip’s curve.
- Length: toenails level with the tip of the toe, a thin white edge left.
- Best time: after a bath, when nails are softer.

How often should you cut your toenails and fingernails?
Nails are hard keratin pushed out from a growing zone under the skin at the base, called the matrix, which is why cutting them doesn’t hurt and why damage to the base shows up weeks later as a ridge or a white mark moving outward. Fingernails grow faster than toenails, faster on your dominant hand, and a little faster in summer.
| Nail | How often | Full regrowth |
|---|---|---|
| Fingernails, adults | Every 1 to 2 weeks | About 6 months |
| Toenails, adults | Every 3 to 6 weeks | 12 to 18 months |
| Older adults’ toenails | Every 4 to 8 weeks | Slower, often thicker |
| Children’s nails | About weekly (fingers) | Faster than adults |
Not sure? Watch your socks. When the white edge starts snagging them or pressing against the inside of your shoe, it’s time.
How to properly cut toenails, step by step
- Soften first. Cut after a bath or after soaking the feet in warm water for 5 to 10 minutes, then dry them. Hard, dry toenails split and crack under clippers.
- Use the right tool. Straight-edged toenail clippers for toes, the smaller curved ones for fingers, and both cleaned with soap and water and then wiped with rubbing alcohol before and after every use, because a dirty clipper is how fungus travels from one foot to another.
- Sit well and see well. Good light, foot flat on a stool or the edge of the bed, glasses on if you use them.
- Cut straight across in two or three small cuts rather than one big snap, which can crack a thick nail.
- Leave a little white. The edge should sit level with the tip of the toe, about 1 to 2 mm of white showing. Don’t cut down into the corners.
- File the sharp points with an emery board, moving in one direction, so the corners don’t snag.
- Leave the cuticles alone, and don’t dig under the nail edges with the clipper tip.
Try this on your big toe
Before cutting, run a fingertip across the end of your big toe. The nail edge should end up just where the skin at the tip stops, and if you can feel it sitting below that line, you’ve been cutting too short. Most people have.
How short should toenails be cut?
Level with the end of the toe. Shorter feels tidier. It isn’t. When a toenail is cut back behind the fleshy tip, and especially when its corners are rounded off, the skin at the sides pushes up and over as you walk, and the regrowing nail edge then grows into that fold. That’s the start of most ingrown toenails. Longer than the toe tip, though, and nails press into shoes, crack, and lift, which is its own route to bruising and fungus.
Fingernails are more forgiving. You can follow the curve of the fingertip, rounded or squared, and a short length is practical for cooking, typing and anyone who handles babies.
Straight across, level with the toe, after a bath: three habits that stop most ingrown toenails before they start.
Ingrown toenails: how they start and the first home care
It’s usually the big toe. The side of the nail presses into the skin, which turns red, sore and swollen and may later start to ooze, and the longer shoes keep pressing on it, the angrier it gets. Common causes are curved or too-short cuts, tight or pointed shoes, stubbing or dropping something on the toe, sweaty feet, and simply having nails that curve a lot, which runs in families.
What to do in the first few days (no infection signs)
- Soak the foot in warm, soapy water for 10 to 15 minutes, a few times a day, then dry it well.
- Wear open sandals or roomy shoes until it settles, and skip tight socks.
- Keep the area clean and dry; let the nail grow out past the skin rather than cutting it shorter.
- Don’t dig out the corner or cut a wedge from the side yourself. “Bathroom surgery” is the usual route from a sore toe to an infected one.
Myth: cutting a V in the middle of the nail pulls the sides out
It doesn’t. A nail grows forward from its base, not inward from the edges, so a notch in the centre changes nothing about how the sides behave and simply leaves you with a jagged nail that catches on everything. Straight-across cuts and roomier shoes do more.
How to cut old people’s toenails, and when to get help
Toenails often thicken, yellow and harden with age, while bending down gets harder and eyesight worse, which is why “can’t reach toenails to cut them anymore” is such a common search. If you’re helping a parent, a few changes make it safe and quick:
- Do it after their bath, with them seated and the foot resting on your knee or a stool with a towel.
- Use sharp, straight toenail nippers and take tiny bites from one side to the other, rather than a single cut, filing a thick nail down from the top with a coarse emery board between cuts so the nippers have less to get through.
- Check the whole foot while you’re there: between the toes, the heels, any sores.
Hand it over to a doctor or podiatrist when nails are very thick, crumbly or discoloured, when the person has diabetes, numbness or poor circulation, takes blood thinners, or when they are frail and the risk of a nick is high. Thick, discoloured nails may be fungus, covered in our toenail fungus guide.
Night-time nail cutting, and other things elders said
Many South Asian families still avoid cutting nails after dark, and some prefer a particular day of the week. The practical root is easy to see: in homes lit by lanterns, a sharp blade or scissors and dim light meant cut fingers. Clippings were gathered and thrown away rather than left on the floor, which is simply good hygiene, and the whole custom is a tradition worth respecting even though, with a proper light overhead, cutting at night causes no harm at all. Respect it. Don’t fear it.
Other nail beliefs? Shakier. White spots on nails are usually from small knocks to the base, not calcium shortage; the nails that split, peel or show white spots guide explains what does and doesn’t matter. Biting nails and tearing off hangnails, meanwhile, really do invite infection at the nail fold. The two-minute nail care habit fixes the hangnail problem with a bit of oil and a file.
Get a toe seen within a day or two if you notice pus, redness spreading beyond the nail fold, red streaks up the foot, a toe that’s hot and throbbing, or a fever. With diabetes, numb feet, poor circulation or a weak immune system, don’t treat an ingrown or infected toenail at home at all; go early, and follow the diabetic foot check routine every day. Ingrown nails that keep coming back can be fixed with a short procedure under local anaesthetic, done by a doctor or podiatrist. A dark streak running along a nail that you can’t explain by an injury also needs a doctor’s look. Never share nail clippers, and keep them away from children.

Cutting nails: what people ask
How often should you cut your toenails?
Every three to six weeks for most adults. Toenails are slow. Cut when the white edge starts to catch on socks or press against your shoes.
How often should I cut my fingernails?
Every one to two weeks, because fingernails grow roughly three times faster than toenails. People who cook, type a lot or care for babies usually prefer them short and trim weekly.
How do you properly cut toenails?
After a bath, with clean straight-edged clippers, cut straight across in two or three small snips, leave the edge level with the tip of the toe, and file the corners smooth. Don’t round the corners down or dig into the sides.
How short should toenails be cut?
Level with the end of the toe, with about 1 to 2 mm of white showing. Cutting shorter than the toe tip lets the skin fold over the edge, which is how many ingrown toenails begin.
Should you cut toenails straight or curved?
Straight across. Curving the corners down encourages the nail edge to grow into the skin. Fingernails can follow the fingertip’s natural curve because they rarely become ingrown.
Is it better to cut nails before or after a bath?
After. Warm water softens nails so they cut cleanly instead of cracking or splitting, but dry your hands and feet first, because wet fingers on a clipper slip.
Can I treat an ingrown toenail at home?
A mild one without infection signs, yes: warm soapy soaks, roomy shoes, and letting the nail grow out. Don’t cut into the corner yourself. See a doctor for pus, spreading redness, fever, or if you have diabetes or poor circulation.
How do I cut an elderly person’s thick toenails?
After a bath, with them seated and the foot supported, use straight toenail nippers to take small bites across the nail, filing it down from the top between cuts. Very thick, crumbly or painful nails, or anyone with diabetes, are best left to a podiatrist.
Why shouldn’t we cut nails at night?
It’s a tradition from homes lit by lanterns, when sharp blades and dim light meant cuts and lost clippings. With good lighting there’s no harm in cutting nails at night. Clean up the clippings either way.
Can a diabetic person cut their own toenails?
Only if they can see and reach well and have good feeling in their feet, cutting straight across after a bath. With numbness, poor circulation, poor eyesight or thick nails, a podiatrist or trained family member should do it.
How long does it take a toenail to grow back?
About 12 to 18 months for a whole toenail. Fingernails take around six, which is why a bruise or ridge from an injury seems to hang around forever.
How do I clean nail clippers?
Scrub them with soap and water, dry, then wipe the blades with rubbing alcohol before and after each use. Don’t share clippers, even within the family, because fungus spreads easily on shared tools.
