Beard Neckline: Where It Should Sit and How to Keep It at Home

Finding the right height with two fingers

Place your index and middle fingers flat across your throat, with the lower finger resting on top of your Adam's apple. The top edge of your upper finger is roughly where the centre of the neckline goes; for a shorter, tighter beard, use one finger instead of two.

Most people find the natural crease where the underside of the chin meets the neck sits right about there. If you tilt your head down slightly, that crease is the line a well-set neckline follows.

The curve from ear to ear

The neckline is not a straight horizontal cut; it is a U. From the centre point, it runs back and gently upward along the underside of the jaw and finishes just behind the earlobe, where the jawbone turns up toward the ear.

Picture a line from the back of one earlobe down to your centre point and up to the other earlobe. The curve should be smooth, with no corners at the sides. A sharp angle under each jaw corner is what makes a neckline look home-cut.

• Centre: one to two fingers above the Adam's apple.
• Sides: follow the underside of the jaw, staying below the bone.
• Ends: just behind the earlobe, meeting the sideburn or fade.

The too-high mistake and why it happens

Setting the neckline too high is the error we fix most often. People look straight into the mirror, see hair on the underside of the jaw and shave up to the jawbone, because that is where the face appears to end from the front.

The result is a beard that looks pasted onto the face. From the side the jaw loses its shadow, the chin looks weaker and any softness under the chin becomes more visible, not less. It also takes weeks to recover, because the hair you removed has to regrow to the full beard length before the line can be moved back down.

The opposite mistake, leaving the neckline too low, is easier to spot: the beard runs down the throat and looks untidy at the collar. It is also quicker to fix, since cutting a line higher takes seconds.

How to shave below your neckline at home

Once a barber has set the line, your job at home is to keep the skin underneath clean without moving the line itself. Do it every two to four days, before the stubble below starts blurring the edge.

1. Tilt your head back and look at the line in good light; a hand mirror helps with the sides.
2. Run a trimmer without a guard, or a foil shaver, up to about 3 mm below the line, never on it.
3. If you use a razor, soften the stubble with warm water first and shave with the grain to reduce irritation.
4. Leave the last few millimetres and the line itself for your barber.
5. If you get bumps on the neck, see our advice on preventing razor bumps and ease off the razor.

Faded or hard neckline?

A hard neckline is a clean razor edge between beard and bare neck. It looks sharp and deliberate and suits most short and medium beards. A faded neckline blends from the beard length down to skin over a centimetre or two, which looks softer and grows out more forgivingly.

For long beards, the neckline gets hidden under the hair falling over it, so a faded edge is often the better choice; our long beard page explains that setup. Either way, the line is set during a Beard Only + Lineup and reset every one to two weeks.
