Most haircut miscommunications happen in the first 60 seconds at the chair. Words like "short," "a bit off," or "tidy it up" mean entirely different things to different barbers and different clients. The solution is specificity: guard numbers for the sides, inches or centimetres for the top, a named neckline type, and reference photos. This guide gives you the exact vocabulary and questions to cover every element of a cut before the clippers start.
Start with reference photos — always
Bring two or three reference photos that show the style you want from the front, one side, and ideally the back. Photos eliminate ambiguity that verbal description cannot bridge. "Short back and sides with more on top" describes thousands of different haircuts; a clear photo narrows it to one. Choose photos of people whose hair texture and density are similar to yours — a straight fine-hair photo won't translate directly to thick curly hair. Show the photos before the barber picks up any tools, not during or after.
Barber tip: If you can't find one perfect photo, bring two: one showing the length and shape you want on top, and a second showing the sides or fade height you're after. Barbers can combine references from two photos more easily than they can invent a style from a vague description.
Guard numbers for the sides and back
Clipper guards are numbered, and each number corresponds to a fixed length. Using numbers means you get the same result every time, from any barber. See the clipper guard sizes chart for the full mm-to-number reference. The key numbers for sides and back:
- No guard — about 0.5–1mm with the lever closed; the base of most skin and bald fades
- #0.5 — 1/16" (1.5mm), near-skin (very tight)
- #1 — 1/8" (3mm), close but shows a shadow of hair
- #1.5 — 3/16" (4.5mm), a useful in-between for blending
- #2 — 1/4" (6mm), a classic short back and sides
- #3 — 3/8" (10mm), medium-short sides
- #4 — 1/2" (13mm), medium sides, still clippered
Say: "I'd like a #2 on the sides and back." Done — no ambiguity. Guard sizes can vary slightly between brands, so if you've found a length you like, ask the barber to note the numbers they used. If you want a fade instead of a single length, specify the fade height: low, mid, or high (referring to where the shortest section starts) and how short it goes at the bottom (e.g. "down to a #0.5" or "down to skin"). For more on the difference, see the fade haircut guide or the taper guide if you want a softer version.
Fade vs taper — know the difference before you ask
A taper is a short, conservative graduation that is usually limited to the sideburns and the neckline — the rest of the sides keep visible length, and the hairline is simply cleaned up and softened. A fade is a graduated blend that runs further up the sides and back and takes the bottom down to very short hair or bare skin, creating a sharper, higher-contrast finish. Fades need more frequent upkeep (every 2–3 weeks to stay crisp); tapers grow out gracefully over 4–6 weeks. If you want sharp and modern, say fade; if you want classic and lower-maintenance, say taper. Say "skin fade" if you specifically want the bottom taken to bare skin, and "taper fade" if you want a fade that only shows at the sideburns and neckline. The taper fade guide shows the in-between option.
One more term worth knowing: an undercut is not a fade at all. The sides are cut to one short length with no blend, leaving a visible disconnection under the longer top. If that's what you want, ask for it by name — see the undercut guide.
Describing the top in useful terms
Give the barber two pieces of information about the top: the length you want to keep, and the texture or feel you're after.
- Length — use inches or centimetres. "About an inch and a half on top" or "I want to keep three inches up there." Avoid "short," "medium," and "long" — they mean different things to everyone.
- Texture — say whether you want it blunt-cut (uniform, heavier, holds shape), point-cut (softer edges, natural movement), or thinned/texturised (bulk removed, usually for thick hair). If your hair is very thick and you want it to sit flatter, tell the barber to thin it out.
- Direction — describe how you wear it: "I push it back," "I side-part it on the left," "I let it fall forward." This tells the barber which direction to cut for.
Neckline: your three options
Every barber needs to know what you want at the neckline before they finish. The three standard options:
- Blocked / squared — a straight horizontal line across the nape with two vertical lines at the sides. Clean and deliberate. Grows out visibly fast because you can see the line shift upward over two weeks.
- Rounded — follows the natural curve of the back of the skull. Softer than squared, grows out more neatly. A good all-rounder for most styles.
- Tapered / natural — the neckline feathers into the skin rather than ending in a defined line. The most natural-looking result and the most forgiving as it grows out. If you're unsure, ask for this one.
Fringe, sideburns, and the part
Cover these three elements before you sit down if they apply to your cut:
- Fringe — specify where you want the fringe to sit (above the brow, at the brow, below it) and whether you want it blunt (straight edge) or textured (point-cut). A blunt fringe is a deliberate, stylised look; a textured fringe is more casual and movement-friendly. For a messy fringe, see the script below.
- Sideburns — specify how long. "Level with the bottom of the ear canal," "mid-ear," or "tapered off" are all clear enough. Unspecified sideburns are where barbers make quick decisions that can affect how the whole cut looks.
- Part — if you want a defined parting, tell the barber which side and whether you want it sharp (a hard part, sometimes shaved in) or natural (just combed in). Check our face shape guide if you're unsure which side a part suits your features better.
Copy-paste scripts for popular cuts
Save the one closest to what you want in your phone notes, adjust the numbers, and read it out (or show it) along with your photos. Each one covers sides, top, finish and neckline so nothing is left to guesswork.
French crop
"I'd like a French crop. Mid skin fade on the sides and back, starting from a #0.5 at the bottom and blending up to a #3 by the temples. Leave about 2 inches on top and heavily texture it with point cutting so it sits forward. The fringe should be short and choppy, about half an inch above my eyebrows, not a straight line. Tapered neckline, please."
More detail on lengths and variations in the French crop guide.
Messy fringe (textured fringe)
"I want a messy, textured fringe that falls forward. Please keep about 3 to 4 inches on top so it has enough length to move, and point-cut or slide-cut the ends so they're uneven and piecey rather than blunt. The fringe should sit just at or slightly above my eyebrows when it's dry. Keep the sides a #3 or scissor-cut short, blended into the top with no hard line. Tapered neckline. I'll style it with a matte paste or sea salt spray, so please don't thin it so much that it goes flat."
Two things to mention for a messy fringe: whether you have a cowlick at the front hairline (it changes how short the barber can safely go), and how you'll dry it. Air-dried fringes sit longer and heavier than blow-dried ones. See the fringe haircut guide for fringe types.
Low taper (classic, office-friendly)
"Scissor cut all over, about 1.5 inches on top and 1 inch on the sides. Please taper just the sideburns and the neckline down to a #1, so it looks tidy but grows out naturally. Rounded neckline, sideburns to the middle of the ear. I part it on the left."
Mid skin fade with textured top
"Mid skin fade: start at bare skin just above the ear and blend up to a #2 at the temple line. About 2 to 3 inches on top, point-cut for texture, and I push it up and slightly back. Keep the sideburns faded into the beard line. Line-up at the front, but keep it natural, not pushed back."
Just a tidy-up (keeping length)
"I'm growing it out, so I want to keep as much length as possible. Please take no more than half an inch off the top, just clean up the ends. Tidy around the ears and the neckline so it doesn't look shaggy, and keep the neckline tapered rather than squared so it grows out cleanly."
Quick reference: phrases that get results

| Amount off | "Just a trim" | "Take off half an inch, no more" |
Barber tip: If the barber shows you the length with their fingers or a comb before cutting and asks "is this what you mean?" — say yes or no clearly. This check-in is your easiest opportunity to correct a misunderstanding before any hair is cut. Never nod vaguely and hope for the best.
