Beard Length Chart: From Stubble to Very Long

By The Striking Viking Editorial Team. Published 10.28.2026. Last updated 10.28.2026.

A beard moves through five length stages: stubble (under 3 mm), short (3 to 13 mm), medium (13 to 25 mm), long (25 to 75 mm) and very long (over 75 mm). Measure yours from the skin to the tip of the hair on a dry, combed beard, and the stage tells you roughly how long it took to get there and what it needs from you next.

There is no official scale for beard length, so the names and cut-offs below are our own working bands. We rounded them to numbers that are easy to find on any ruler, in millimeters and in inches. Where we lean on research, we say what it measured and what it did not.

What do the five beard length stages look like in mm and inches?

Here are the stages, with the time each one takes to reach from a clean shave if you never trim.

The time column is our arithmetic, not a promise. A 2019 study in the International Journal of Cosmetic Science photographed hair at five skin sites, including the cheek and chin, in women and men, and measured growth rates between 0.18 and 0.485 mm a day. We divided each cut-off by the slow and fast ends of that range.

Two limits apply. The abstract does not give a beard-only figure, so we use the whole range as outer bounds. And the study measured hairs in their growth phase, a share that differed between the groups of men it looked at, so a real beard can run slower than the fast end.

How do you measure your beard length?

Press a ruler flat against the skin, read to the tip of the hair, and take two readings, one at the cheek and one at the chin. Do it on a dry beard, combed down, because that is the beard you wear and the one you will be trimming.

1. Let the beard dry, then comb it down.
2. Put the zero end of a ruler (a short, stiff one is easier than a tape) against the skin at your cheek, along the direction the hair grows.
3. Read to the tip of the hair as it lies. Don't pull it straight, or a curly beard will measure longer than it ever looks.
4. Repeat at the chin and write both numbers down.

If the two numbers land in different stages, use the longer one to pick your routine, since that is the part that needs the most work. A phone photo with the ruler in the frame, taken the same day each week, shows progress better than memory does.

What does a stubble beard need? (under 3 mm)

Stubble needs a clear neckline and a wash with the rest of your face, and not much else. There is nothing to detangle at this length, so a comb is optional. If you are not sure you want a beard at all, this is the cheapest stage to find out: shave it off and try again in a couple of weeks.

What does a short beard need? (3 to 13 mm)

A short beard is where a comb earns its place. Fine teeth line the hair up and show you which hairs are sitting out of place. The Sandalwood Wooden Beard Comb has coarse teeth on one side and fine teeth on the other. It is made from sandalwood, measures 10 × 6 × 0.5 cm (4 × 2.5 × 0.25 in), and comes with a black carry case.

At this length, trimming means stray hairs and the neckline, not the length itself. If you add oil, a few drops is plenty. Striking Viking Sandalwood Beard Oil conditions and softens beard hair and moisturizes the skin beneath the beard, and our guide to what beard oil does covers how to apply it.

What does a medium beard need? (13 to 25 mm)

At medium length, the shape depends on your scissors as much as your comb. Check the outline every week or so, and trim the length when it starts to look uneven. Take off about an eighth of an inch (3 mm) on the first pass, with the comb holding the hair out as your guide. Our guide to trimming a beard at home goes through it step by step.

The Beard and Mustache Scissors Kit pairs 4.5 inch (11.4 cm) stainless steel scissors with a mini mustache comb that measures 2.75 × 0.75 inches (7 × 1.9 cm), plus a synthetic leather carry case. That small comb is the one that fits into the mustache. If you are still choosing scissors, our guide to beard scissors covers what to look for.

What does a long beard need? (25 to 75 mm)

At long length, how you handle the beard when it is wet starts to matter. The American Academy of Dermatology says hair is delicate when it is wet, so you should use a wide-tooth comb instead of a brush to detangle it. Its August 2024 hair tips add two more points: comb the ends first and keep working higher, and wrap hair in a towel or t-shirt instead of rubbing it dry, since rough rubbing can cause damage. That advice is written for scalp hair, and we have applied it to the beard as the closest guide available.

In practice, the coarse side of the comb does the work, from the tips upward a little at a time. Oil goes on daily from this stage, skin first and then the length. If you use balm for hold, warm it in your palms before it goes near the beard. Customers tell us balm needs working in the palms before it will spread, and our guide to using beard balm walks through it. The full routine, with the research behind each step, is in our long beard care guide.

What does a very long beard need? (over 75 mm)

A very long beard needs the long beard routine, with more time for each step. Expect longer at the comb, longer waiting for it to dry, and more tips to take off. Keep trimming the ends on a schedule, because length you keep is length you have to look after. Once the beard is dry, a brush is fine for smoothing, and our guide to combs versus brushes covers when each one earns its place.

Beard length chart FAQ

How do I know my beard length?

Measure with a ruler from the skin to the tip of the hair, on a dry, combed beard. Take one reading at the cheek and one at the chin, then find the stage in the chart above that matches the longer number.

How long is 3 mm stubble?

3 mm is about 1/8 of an inch. From a clean shave, that is roughly 1 to 2½ weeks of growth at the range in the 2019 study.

What is the 3 month beard rule?

It is shorthand for waiting about 90 days before you judge or shape a new beard. Ninety days at 0.18 to 0.485 mm a day comes to roughly 16 to 44 mm (0.6 to 1.7 in), which is medium to long on our scale. Individual beards vary, so measure yours instead of counting days.

How long does it take to grow a beard to 1 inch?

One inch is 25 mm. At the range in the 2019 study, that takes about 7 to 20 weeks from a clean shave with no trimming. A real beard can take longer, so treat the low end as a best case.

What length of beard looks best?

We have no evidence that crowns one length. It depends on your face, how your hair grows and how much upkeep you will actually do. The chart helps with the last part: each stage costs a little more care than the one before it.

Which beard length takes the most upkeep?

Long and very long. By our reading, the wet-hair handling described above starts to matter from about 25 mm, which is why those two stages have the longest routines.

The short version

The five stages are cut at 3, 13, 25 and 75 mm, which is about 1/8, 1/2, 1 and 3 inches. Measure dry from the skin at the cheek and chin, find your row, and use the time column as a rough guide, not a schedule. Stubble needs a neckline, short needs a comb, medium needs scissors, and long and very long need a gentle routine for wet hair.

Next step: if you measured short or longer and don't own a comb yet, start with the Sandalwood Wooden Beard Comb.
