Fingernails grow at varying rates depending on factors such as age, genetics, overall health, and nutrition. On average, fingernails grow at a rate of about 3.47mm per month or about 0.1 to 0.15mm per day. This translates to approximately 1cm of growth every 3 to 4 months. Toenails, on the other hand, grow much slower, at an average rate of 1.62mm per month. The rate of nail growth can also differ based on which finger the nail is on, with nails on the dominant hand and longer fingers growing faster.
| Characteristics | Values |
|---|---|
| Average growth rate | 3.47 mm per month or 0.1 mm per day |
| Toenail growth rate | 1.62 mm per month |
| Time taken to grow back a toenail | 1 year to 1.5 years |
| Time taken to grow back a fingernail | 4 to 6 months |
| Factors affecting growth rate | Age, genetics, overall health, nutrition, diseases, blood circulation, hormones, time of the year, etc. |

What You'll Learn
Fingernails grow faster in the summer
On average, fingernails grow at a rate of about 3.47mm per month or about 0.1mm per day. This rate of growth varies depending on factors such as age, finger, and season. For instance, nails grow faster in the summer and during the day.
Several factors influence the rate of nail growth. Firstly, the nails on your dominant hand tend to grow faster because you use that hand more often, increasing the risk of trauma to the nails. When trauma occurs, your body sends more blood and nutrients to the affected area to aid repair, and this increased nutrient supply may accelerate nail growth.
The specific finger also affects nail growth speed; the little finger's nail grows slower than the other fingernails. Additionally, nail growth is faster during puberty due to fluctuating hormone levels and slows down as hormone levels stabilise with age.
While there are no scientifically proven methods to make nails grow faster, maintaining good nail hygiene and overall health can help strengthen nails and prevent breakage, allowing them to grow longer. For instance, taking biotin supplements and regularly clipping nails can contribute to healthier and longer nails.
Given that nails grow about 3.47mm per month, it would take approximately three months for nails to grow 1 centimetre. However, this duration may vary due to the factors mentioned above, such as the season, dominant hand, finger, age, and overall health.

Toenails grow much slower than fingernails
Fingernails grow at an average rate of 3.47 mm per month, or about a tenth of a millimetre per day. The rate of growth depends on various factors, including age, nutrition, and the season. For instance, nails grow faster during the day and in the summer. They also tend to grow faster on the dominant hand and on longer fingers.
Toenails, on the other hand, grow at a much slower rate of 1.62 mm per month. This means that fingernails grow a little over twice as quickly as toenails. If you lose a toenail, it can take up to a year and a half for it to completely grow back—three times as long as a fingernail would take to regrow.
The difference in growth rates between fingernails and toenails is likely due to differences in use and trauma to the nail bed. The nails on the dominant hand grow faster because they are used more often, which also increases the risk of trauma. Similarly, the frequency and strength of mechanical forces on the nails can affect their growth rate. For example, carpenters' nails, which are subject to greater mechanical forces than office workers' nails, have a lower curve index.
While there are no scientifically proven methods to make nails grow faster, maintaining good nail hygiene and taking biotin supplements can help improve nail health and prevent breakage. Additionally, nail biting has been observed to increase the rate of nail growth, possibly due to the increased blood and nutrient supply to the affected area.
Overall, the growth rate of nails, both fingernails and toenails, is influenced by a combination of genetic, environmental, and individual factors. While some factors, such as age and season, are beyond our control, others, such as nutrition and nail care, can be managed to promote healthy nail growth.

Nails grow faster on dominant hands
It takes about six months for a fingernail to grow back if you've lost one, and a toenail can take up to a year and a half to fully regrow. On average, fingernails grow at a rate of 3.47mm per month or about 0.1mm per day.
Now, is there any truth to the claim that nails grow faster on dominant hands? Well, yes! The nails on your dominant hand grow faster because you use that hand more often. This increased use leads to more blood circulation in the fingertips of your dominant hand, promoting nail growth. Additionally, any trauma to the nail, such as catching it on something or biting it, can stimulate circulation in the nail bed, resulting in faster nail growth. So, if you're right-handed, your right hand nails will likely grow faster, and the same goes for left-handed individuals and their left hand.
Several factors influence nail growth rates, including the time of year, age, and which finger the nail is on. For example, the little finger's nail typically grows slower than the other fingernails. Nail growth is said to peak during puberty and then gradually decline as hormone levels stabilise with age. Starting at age 25, the rate of growth decreases by approximately 0.5% per year.
While there are no scientifically proven methods to make nails grow faster, maintaining good nail hygiene and overall health can positively impact nail growth. Taking biotin, for instance, can help strengthen nails and prevent breakage. Additionally, regular nail clipping can promote nail growth without the risks associated with nail biting.

Children's nails grow faster than adults'
On average, fingernails grow about 2.5 to 3.5 millimeters per month or about a tenth of a millimeter per day. At this rate, it would take about 3 to 6 months to grow a full centimeter of the nail. The rate of growth depends on various factors, including age, nutrition, genetics, and the season. Nails on the dominant hand, longer fingers, and toenails tend to grow faster. Toenails, however, grow much slower than fingernails.
The growth rate of nails tends to decrease with age. Starting at age 25, the rate of nail growth decreases by approximately 0.5% per year. By observing nails, doctors can detect changes associated with skin problems, lung disease, anemia, and other medical conditions. For example, longitudinal melanonychia, a brown-black pigmented band on the nail, is caused by the presence of melanin in the nail plate. In children, the primary cause of this condition is nail matrix nevi, which may be present at birth or develop between the ages of 2 and 4.
While there are no scientifically proven methods to accelerate nail growth, maintaining good nail hygiene and overall health can help support the growth process. Proper nail care, including regular clipping and avoiding nail-biting, can also contribute to stronger and healthier nails. Additionally, nutritional deficiencies or underlying health conditions may cause slow nail growth, discoloration, or other abnormalities, so it is important to consult a doctor if any of these symptoms arise.

Nail growth slows with age
On average, fingernails grow at a rate of about 3.47 millimeters (mm) per month, or about a tenth of a millimeter per day. This equates to approximately 1 centimeter every 29 days.
However, it's important to note that nail growth is influenced by various factors, including age, with growth rates slowing as individuals get older. Starting at age 25, the rate of nail growth is said to decrease by approximately 0.5 percent per year, according to the NCBI. This change in speed has been attributed to the slowing of blood circulation with age.
Hormone levels also play a role in nail growth rates, with growth peaking during puberty and declining as hormone levels balance out with age. For example, pregnancy has been associated with rapid nail growth, while lactation may lead to slower growth.
In addition to slower growth, aging nails may undergo changes in appearance and texture. They can become dull, brittle, and discolored, turning yellow or opaque. The curve of the nails may also change, with a dramatic shift indicating a potential health issue. Certain conditions, such as diabetes, circulatory issues, and nutritional deficiencies, can further impact nail growth and health.
While there is no guaranteed way to speed up nail growth, maintaining overall health and practicing good nail hygiene can help support nail growth and prevent breakage.
