How to Trim a Beard

Look sharp and polished, even without expert fading and tapering. The easy way to trim and tidy your beard between barber visits.

Only big, bushy beards need the clipper-over-comb technique of a skilled professional. If you keep yours at medium length or shorter, you’ll only need a barber to provide a smooth transition from beard to temple when getting a haircut.

And if your head is buzzed or shaved, you probably won’t need one at all.

Here’s how to keep your beard looking tip-top between barber visits—or entirely on your own.

How Often Should You Trim a Beard?

Trim your beard whenever it starts to lose shape—usually every few days for short styles and once a week or so for medium beards. If you dye your beard to cover grays or even out color, do this before trimming. The color will then appear more natural and less saturated.

Supplies Needed

A beard trimmer with guards ranging from 1 to 7 mm.
A pocket comb. A mustache comb is too small for a full beard. Make sure it’s hand-sawn or made from carbon. Molded plastic combs have a seam that damages the hair cuticle.
A beard brush. Choose natural boar or sisal bristles. These are anti-static and give smooth results.
Mustache or hairdressing scissors.
A Wilkinson Sword Precision Styler (or equivalent).
Beard contour stencils (optional).
A hand mirror.

6 Easy Steps to Trimming a Beard at Home

1. Brush or Comb Your Beard

Brushing is best, but a comb will do.

Brush downward so the beard and mustache lie flat. The hair should be completely dry. Water reduces curl, which adds length and leads to trimming off more than intended.

As long as your beard is free of dirt and sweat, and any previously applied beard balm or oil is fully absorbed, there’s no need to wash your beard before trimming.

2. Reduce Bulk

Debulking is the process of removing excess weight. For short to medium beards, clippers are the only necessary tool.

Start with the largest guard to avoid cutting off too much hair, reducing the size until your beard is of the desired length.

Short Beards

For short beards, trim against the grain (against the direction of growth), working from the neck up.

If you’re growing a beard-stache, treat the mustache as described below under “Longer Beards.”

As an amateur, don’t try to achieve a perfect transition from sideburn to temple. Instead, bring the clippers up only as far as beneath the cheekbone, then pull or flick away.

For shaved heads, instead of attempting a fade, angle off at about the top third of the ear, following the beard’s natural diagonal cheek line (see the image below).

Longer Beards

The whiskers of medium-length beards lie flat, overlap, and interlock, creating a more established appearance. To maintain the look, trim with the grain. You’ll otherwise cut too deeply, removing more than just surface bulk, which spoils shape.

Begin at the sideburns on the cheekbone. Again, never try a perfect transition to the temple. As with short beards, men with a shaved head should angle off the sideburn. If there’s too much bulk for this, use a shorter guard from the top of the sideburn, then pull or flick away after about 1/4 of an inch.

If you want to balance face shape, there are two basic rules: fuller faces benefit from bulk at the chin, and narrow faces at the cheeks. To achieve this, simply vary guard length by 2 to 3 mm accordingly. The result should be subtle enough to avoid any need for complicated blending techniques that only a barber can perform.

Very bold examples of this principle are the goatee, which accentuates chin length, and the friendly mutton chops, which adds horizontal weight (see the image below).

3. Define the Neckline

The general rule for a full beard is that the neckline should be placed about two finger-widths (index and middle) above the Adam’s apple; the point at which the neck meets the chin. This strengthens jaw definition. Even so, placement can depend on style.

Using your clippers without a guard, trim from the center with downward strokes, following the beard’s natural curve. If you don’t have a steady hand or an eye for symmetry, invest in a beard stencil set (see the image below).

Comb or brush the neckline to check for whiskers that extend beyond it and snip them off with scissors.

Once you’ve defined the neckline, remove leftover neck hair with upward strokes.

Finally, using a second mirror, inspect the back of the jaw beneath the ear.

4. Define the Cheek Contours

With downward strokes of your trimmer, remove whiskers that stray above the natural cheek contour. Alternatively, use a safety razor, but avoid multi-blade cartridges, which are more prone to clogging with longer whiskers.

If the contour is very irregular, use a trimmer to establish shape.

Remember that the natural line-up for most men is from the corners of the mouth to the top of the sideburns, forming a soft diagonal incline.

If this isn’t the case for you, or you’re unsure, a set of beard stencils can help.

5. Trim the Mustache Contours

You can wear almost any style of mustache with a full beard, but here are the basics for keeping it tidy. To know more, I’ve dedicated an entire article on how to trim a mustache.

For the lower contour, use mustache or hairdressing scissors. Let your lip guide you, but don’t trim too high.

To remove stray whiskers that extend beyond the corners, use a safety razor rather than a trimmer. For better visibility, pull the ends of your mustache inwards.

A safety razor is best for the upper contour. But for the fiddly area directly below the nostrils, use a Wilkinson Sword Precision Styler. This prevents your nose hair from connecting to your mustache.

6. Remove Flyaways

For any beard or mustache wearer, removing flyaways—whiskers that won’t lie flat—is a daily maintenance task.

Brush or comb the beard and snip off any hairs that refuse to lie flat. Use a second mirror to check your profile. Apart from good lighting, dark flyaways stand out more against a light background (e.g., white walls) and lighter ones against a dark background.

Finish with a shower to rid yourself of loose whiskers.

The routine is simpler in practice than it appears on the page and takes about ten minutes. Follow it consistently and your beard will stay sharp, even if you never visit a barber again.
