What a sideburn does
A sideburn is the joint between your hair and your face.
It frames the cheekbone on one side and hands the eye to the jaw on the other, and it is the one part of a haircut that stays visible from the front. Get the line right and nobody notices it. Get it wrong and the face looks longer or rounder than it is, which is why a sideburn is set by proportion rather than by trend.
Where it should end
The landmark is the ear, not a number. Three positions cover almost every face:
Proportion
A sideburn is set by the face it sits on, not by the season.

Tapered or squared
Once the length is set, the shape decides how sharp it reads.
Tapered fades the sideburn gradually into the skin at the top. It is softer, it forgives a few days of growth, and it suits most men and most cuts — the taper is what makes the line look natural rather than drawn.
Squared puts a defined corner on the sideburn where it meets the hair. It reads precise and deliberate and pairs with a very short cut or a strong jaw. It also loses its shape fastest, because a hard corner has nothing to hide behind.
A third option is the zero taper — the sideburn taken down to skin at the bottom and left long at the top, which connects the cut to a beard without a visible seam. It is the finish behind most of the sharpest cuts in the room, and it needs a barber who cuts it the same way twice.
Matching it to the cut and the face
A sideburn cannot be chosen on its own. It has to agree with the haircut above it, the beard below it, and the face between.
With a very short cut, the sideburn should be short and tapered, or the head reads top-heavy. With longer hair, it can run to the bottom of the ear and soften the transition. With a beard, the sideburn’s job changes entirely: it stops framing the cheek and starts feeding the beard, so the two are cut as one continuous line.
Faces set the direction. A round face wants a longer, lower sideburn to add length; a long, narrow face wants a shorter one at mid-ear so nothing is stretched further; a strong jaw can carry a squared corner that a softer jaw cannot.
What to say at the chair
Say where you want the line to end — mid-ear, bottom of the ear — and whether you want it tapered or squared. If they are uneven, say that too, and let the barber bring the long one down to the short one rather than the other way round: cutting the high side lower to match is what turns a small unevenness into a fortnight of waiting.
If you are between haircuts and the only thing that has gone soft is the taper, it can be tidied on its own. The full menu and prices are here, and the neckline is the other line that decides how new a cut looks.
Questions
How long should a man’s sideburns be?
To the middle of the ear for most faces, to the bottom of the ear for a longer cut or a rounder face, and no further than the earlobe unless they are growing down into a beard. Length is a proportion decision: the longer the sideburn, the shorter the face reads.
Where should a sideburn end?
The landmark is the ear, not a measurement. Mid-ear is the default; the bottom of the ear suits longer hair and full faces; below the earlobe only works when the sideburn is joining a beard. A line that stops above the mid-ear almost always looks unfinished.
Should sideburns be tapered or squared?
Tapered — a gradual fade into the skin — is softer and more forgiving and suits most men. Squared, with a defined corner, reads sharper and pairs with a very short cut. Squared needs tidying more often, because a hard corner loses its shape first.
How often do sideburns need trimming?
They grow out on the same clock as the neckline — two to three weeks before a defined shape goes soft. With a shorter cut, the sideburn taper is usually the first thing to go, which is why the tidy between haircuts is worth booking.
Can sideburns be fixed if they are uneven or too short?
Yes, though the fix is patience rather than scissors. The higher side sets the limit: the barber brings the longer one up to meet it, then lets both grow back together. Cutting the high side lower to match is what turns a small unevenness into a two-week problem.
