Hair Length Chart: Inches and Centimetres, Tier by Tier
Fourteen length tiers, from buzz cut to classic length, with the numbers the top-ranking guides actually publish. Find your tier, read the inches and centimetres beside it, and check the grow-out column before you commit to a growing plan. Where the guides disagree, both numbers sit in the cell with a name on each.
| Length Tier | Where It Lands | Inches (as the guides state them) | Centimetres (source-given or converted) | Growing Out to This Tier | What the Guides Call It |
|---|---|---|---|---|---|
| Buzz cut | No visible length past the hairline; the clipper guard is the length | "Less than 1 inch" (shunsalon.com) | 2.5 cm (shunsalon.com) | No grow-out figure in any opened guide; hairfinder's ladder starts at ear length | Buzz Cut (shunsalon.com, aplusnailssalon.com); Induction Cut and Crew Cut in the same clipper family (aplusnailssalon.com) |
| Crop / pixie | Above the jawline | Short Crop 1-2 in (shunsalon.com); Classic Pixie "typically sits around 1-3 inches long" (aplusnailssalon.com) | 2.5-5 cm for the crop band (shunsalon.com); no guide gives a pixie figure in centimetres | No grow-out figure stated | Short Crop (shunsalon.com); Classic, Textured and Long Pixie (aplusnailssalon.com) |
| Ear length | At or just above the earlobes | 6 in for straight hair (hairstylecamp.com); "approximately 2 to 4 inches from the crown" (lorealparisusa.com) — a live dispute: same tier, two different numbers, and lorealparisusa.com states its basis as crown-to-ends | 10-15 cm (wimpole.com); 6 in × 2.54 = 15.2 cm (arithmetic on hairstylecamp.com's figure) | The starting rung of hairfinder's ladder; no months below it | Ear Length (hairstylecamp.com); ear length hair (lorealparisusa.com, wimpole.com); Ear-Length Hair (aplusnailssalon.com) |
| Chin / jaw length | At the jawline or the chin | 8 in straight (hairstylecamp.com); 6-8 in (lorealparisusa.com); 4-6 in (shunsalon.com) — three published positions, all stated, none reconciled | 15-20 cm (wimpole.com); 10-15 cm (shunsalon.com); 8 in × 2.54 = 20.3 cm (arithmetic on hairstylecamp.com's figure) | Ear to chin: 6 months (hairfinder.com, at 0.5 in per month on a 5 ft 7 in frame) | Chin-length (hairstylecamp.com); Chin-length hair (lorealparisusa.com, wimpole.com); Chin Length (shunsalon.com); Jaw-Length Bob and Chin-Length Bob (aplusnailssalon.com) |
| Neck length | At the nape, base of the neck | No natural-hair guide states one; wimpole.com's 20-30 cm converts to 7.9-11.8 in (arithmetic). Extension chart, different basis: 10 in straight = Neck-length (abhair.com, wig drop) | 20-30 cm (wimpole.com) | Chin to neck: 3-4 months (hairfinder.com) | Neck-length hair (wimpole.com); Neck-Length Hair and Chin-to-Neck Length Hair (aplusnailssalon.com) |
| Shoulder length | The ends touch the shoulder point | 12 in straight, 14 in wavy, 16 in curly (hairstylecamp.com); "around twelve inches" (lorealparisusa.com); 12-15 in (shunsalon.com) | 30-40 cm (wimpole.com); 30-38 cm (shunsalon.com); 12 in × 2.54 = 30.5 cm (arithmetic on hairstylecamp.com's figure) | Neck to shoulder: 3-4 months (hairfinder.com) | Shoulder-length (hairstylecamp.com); Shoulder-length hair (lorealparisusa.com, wimpole.com); Shoulder Length (shunsalon.com); Shoulder-Length Hair (aplusnailssalon.com); wig charts put 12 in at the shoulder for straight hair (abhair.com, vietnamhairsuppliers.com) |
| Collarbone / lob | The ends land at the collarbone | No natural-hair guide gives an inch figure; wimpole.com's 30-35 cm converts to 11.8-13.8 in (arithmetic). Wig basis, for contrast: 10 in "can fall near your collarbone" (subellahair.com), 16 in "falls around the collarbone" (vietnamhairsuppliers.com) | 30-35 cm (wimpole.com) | Shoulder to collarbone: 4 months (hairfinder.com) | Collarbone-length hair (wimpole.com); Collarbone-Length Hair (aplusnailssalon.com); Long Bob / Lob (aplusnailssalon.com); gfuhair.com's wig guide calls 16-18 in "collarbone to upper back" |

Wig basis, different landmarks for the same numbers: 16 in = bra strap (subellahair.com), 20 in = mid-back (vietnamhairsuppliers.com, abhair.com), 22 in = lower back (abhair.com) | 55-65 cm (wimpole.com); 60-75 cm (shunsalon.com); 20 in × 2.54 = 50.8 cm (arithmetic on lorealparisusa.com's figure) | Collarbone to bra strap: 12 months; chin-length start to bra strap: "about 20 months" (hairfinder.com). Internal note: hairfinder.com's own leg figures from chin sum to 22-24 months, not 20 — both the stated total and the sum are shown, unadjusted. Bra strap to mid-back: 6 months more | Bra Strap Length (hairfinder.com, aplusnailssalon.com); mid-back (hairstylecamp.com, lorealparisusa.com, shunsalon.com, wimpole.com); aplusnailssalon.com splits bra strap and mid-back into two separate tiers; subellahair.com's wig chart calls 18 in "around your shoulder blade" |
| Waist length | At the natural waistline | 30-36 in (shunsalon.com); wimpole.com's 65-75 cm converts to 25.6-29.5 in (arithmetic) — the two charts disagree at this tier and both numbers stand | 65-75 cm (wimpole.com); 75-90 cm (shunsalon.com) | Mid-back to waist: 8 months (hairfinder.com) | Waist Length (shunsalon.com, hairfinder.com); Waist-length hair (wimpole.com); Waist-Length Hair (aplusnailssalon.com); wig charts: 26 in "can reach your waist" (subellahair.com); gfuhair.com groups 24-30 in as "lower back to waist" |
| Hip length | At the hip bone | 36-42 in (shunsalon.com); wimpole.com's 75-85 cm converts to 29.5-33.5 in (arithmetic) | 75-85 cm (wimpole.com); 90-105 cm (shunsalon.com) | Waist to hip: 9 months (hairfinder.com) | Hip Length (shunsalon.com); Hip-length hair (wimpole.com); Hip-Length Hair (aplusnailssalon.com); wig charts: 28 in "pass your hips" (subellahair.com); abhair.com puts 26 in at hip length |
| Tailbone length | At the tailbone | 42-48 in (shunsalon.com); wimpole.com's 85-95 cm converts to 33.5-37.4 in (arithmetic) | 85-95 cm (wimpole.com); 105-120 cm (shunsalon.com) | Hip to tailbone: 5 months (hairfinder.com) | Tailbone Length (shunsalon.com, hairfinder.com); Tailbone-length hair (wimpole.com); Tailbone-Length Hair (aplusnailssalon.com); wig chart: 30 in "fall near your tailbone" (subellahair.com) |

Source notes: Every cell above is drawn from the ten top-ranking guides opened on 14 September 2026. The inch figures belong to hairstylecamp.com (straight/wavy/curly column), lorealparisusa.com (crown-to-ends basis, stated on its page), and shunsalon.com. The centimetre bands belong to wimpole.com and shunsalon.com. The wig and extension mappings belong to subellahair.com, abhair.com, vietnamhairsuppliers.com and gfuhair.com, and they measure the hair piece itself, not your head. The grow-out legs and the 0.5 in per month rate belong to hairfinder.com, which states its average is based on a woman of 5 ft 7 in; wimpole.com's competing 0.6-1.5 cm per month rate is quoted in the growth section below. Every ÷ 2.54 and × 2.54 result is labelled arithmetic because it is multiplication on the fixed definition of an inch, not a number any guide published. Full URLs are in the CSV.
The full chart, including the source URL list for every row, is available as a CSV.
- Shoulder, straight hair: 12 in × 2.54 = 30.5 cm (12 in from hairstylecamp.com)
- Chin, straight hair: 8 in × 2.54 = 20.3 cm (8 in from hairstylecamp.com)
- Mid-back: 20 in × 2.54 = 50.8 cm ("around twenty inches" from lorealparisusa.com)
- Neck, reverse direction: 20-30 cm ÷ 2.54 = 7.9-11.8 in (20-30 cm from wimpole.com)
- Waist, reverse direction: 65-75 cm ÷ 2.54 = 25.6-29.5 in (65-75 cm from wimpole.com)
- Growth rate: 0.5 in per month × 2.54 = 1.27 cm per month (0.5 in from hairfinder.com)
Formula: centimetres = inches × 2.54, and inches = centimetres ÷ 2.54. The starting numbers belong to the guide named beside them; the multiplication is arithmetic on the fixed definition of an inch. Four of the ten opened guides show both units (shunsalon.com, abhair.com, subellahair.com, gfuhair.com), and three of those four are wig or extension sellers whose inch-to-landmark mapping runs on a different basis; six of the ten never pair the two units at all, and no guide in the set writes out the arithmetic.
Guides were opened on 14 September 2026. Reading each guide's own numbers against its own date shows whether the figures converge over time:
| Guide (URL in CSV) | Published / updated | The numbers it states |
|---|---|---|
| vietnamhairsuppliers.com | 3 September 2025 (JSON-LD) | Wig tiers 6-22 in; 20 in = mid-back |
| shunsalon.com | 24 November 2025 | Dual-unit ladder: buzz 2.5 cm through classic 48-54 in / 120-135 cm |
| subellahair.com | 27 November 2025 | Wig tiers 8-32 in with cm pairs; 16 in = bra strap |
| wimpole.com | 29 December 2025 | Centimetre ladder 0-4 through 110-125 cm; growth 0.6-1.5 cm per month |
| hairstylecamp.com | 5 June 2026 | Chin 8 in; shoulder 12; armpit 18; mid-back 24-26 in, by texture |
| lorealparisusa.com | 9 June 2026 | Chin 6-8 in; shoulder ~12; armpit ~16; mid-back ~20 in |
The dated set does not converge: the two most recent updates (June 2026) disagree with each other by four inches at mid-back, and the older centimetre ladder from December 2025 disagrees with the inch ladders at waist and below. hairfinder.com, abhair.com, gfuhair.com and aplusnailssalon.com display no publication or update date, so their figures are used in the chart above and excluded from this dated comparison. The reading of the dates is this page's own comparison, laid out so you can check it against the CSV.
Why the Same Inch Lands at Two Different Places
Three measurement bases run through the top ten, and mixing them is how a chart starts to look broken:
- Crown to ends, on your head. lorealparisusa.com states it plainly: "professionals typically measure the length of hair from the crown of your head down to the very ends of your strands." wimpole.com's centimetre bands and hairstylecamp.com's inch tiers run on this idea of a worn length.
- The strand itself, stretched straight. gfuhair.com takes its wig measurements "stretched from crown to ends" of the piece, and aplusnailssalon.com's FAQ says hair length is "measured from the scalp to the ends when the hair is stretched straight."
- The wig or extension piece's own length. subellahair.com, abhair.com and vietnamhairsuppliers.com map the piece's inches onto where it falls on a body.
The clash is visible in one number: 16 inches sits at armpit level on lorealparisusa.com's natural-hair chart and at bra strap level on subellahair.com's wig chart. Same number, two landmarks, because the things being measured are not the same thing. When you quote a number in the salon, quote it with its basis.
Growing It Out: Two Rates, One Set of Months
hairfinder.com publishes the only grow-out ladder in the set: 0.5 inch per month, averaged on a 5 ft 7 in frame, with the leg times listed tier by tier in the chart above (ear to chin 6 months, chin to neck 3-4, neck to shoulder 3-4, shoulder to collarbone 4, collarbone to bra strap 12, then 6, 8, 9, 5 and 6 months down to classic). wimpole.com publishes a different rate without the ladder: "your hair grows 0.6-1.5 cm each month," which converts to 0.24-0.59 in per month. hairfinder's 0.5 in (= 1.27 cm) sits inside wimpole's range, but the two pages never reference each other, and this page does not average them. If your growth runs at the bottom of wimpole's band, every leg in hairfinder's ladder stretches by roughly double; if it runs at the top, the legs shrink. Track your own roots between two trims and the months column becomes your column.
Two honest notes on hairfinder's own numbers: the stated "about 20 months" from a chin-length start to bra strap length does not equal the sum of its own legs, which is 22-24 months — both figures are carried, unadjusted. And the page's observation that "every quarter inch is more visible" at long lengths is the practical reason the months between rungs feel longer the further down the ladder you go.
Say the Landmark in the Chair
- Lead with the body landmark, use the number second. "Collarbone length, which the charts put near 12 inches" survives a basis mismatch; a bare "12 inches" does not. The stylist's tape starts where your hair starts, and lorealparisusa.com's crown-to-ends convention shows why the starting point belongs in the sentence.
- Name the tier twice, in two vocabularies. "Bra strap length, the charts also call it mid-back" covers the naming split that runs through the whole top ten — aplusnailssalon.com even sells bra strap and mid-back as two different tiers.
- If you are growing, book the endpoint, not the date. The months column is an average on a stated frame (hairfinder.com, 5 ft 7 in, 0.5 in per month). Ask for a length check against the landmark at each visit rather than promising yourself a calendar date.
Measure Your Own Target
The chart above is the guides' numbers. Your own distance from crown to a landmark is the one that decides where the ends actually land. Enter it and get the other unit:
→ —
- Use a flexible tape and stand straight; a second pair of hands helps keep the tape on the same path.
- Start at the centre of the front hairline, run the tape over the crown and down the back of the head and neck to the landmark in the row you picked.
- Measure the body path, not a loose strand, so the target repeats itself month after month.
- Measure dry, in the usual part and the usual texture. Curly and wavy hair shrinks: wimpole.com puts the appearance gap at 1-2 in for wavy, 2-3 in for curly, and up to half for very coily hair, so note a stretched measurement separately if you want a stylist to account for it.
What the Chart Cannot Decide for You
- Your growth rate. The two published rates (0.5 in per month, hairfinder.com; 0.6-1.5 cm per month, wimpole.com) are averages, and neither page claims to describe your scalp. Only a root-tracking measurement between two trims does that.
- Your height and torso. hairfinder.com builds its months on a 5 ft 7 in average and says so; wimpole.com warns its bands are averages that move with height and body proportions. A collarbone on a long-necked, long-torsoed frame is a different distance from the crown than the same landmark on a compact one, and no page in the set adjusts for it.
- Your texture. The shrinkage numbers exist (wimpole.com: wavy 1-2 in, curly 2-3 in, coily up to half; subellahair.com: buy wavy or curly wigs 2-3 in longer; hairstylecamp.com: "varies with shrinkage" below the chin, +2 in wavy and +4 in curly at shoulder and armpit) but they are appearance figures, not measurements of your curl pattern. The hair texture chart and the hair types chart cover that ground properly.
- Trim cadence. None of the ten guides states how trims interact with net growth over a growing-out plan, so no such figure appears here; hairfinder.com's own page is the only one that frames growth as arithmetic at all.
Honesty note. Every inch, centimetre, month, and growth rate on this page is a figure a named guide published, and the guide's name sits beside it. Where the guides disagree — 6 versus 2-4 inches at ear length, 8 versus 6-8 versus 4-6 at chin, 16 versus 18 at armpit, 20 versus 24-26 at mid-back, waist bands four inches apart, two different growth rates — both sides are shown and none is averaged away. Every × 2.54 and ÷ 2.54 result is labelled arithmetic on the fixed definition of an inch. Wig and extension mappings are marked as their own basis and are never blended into the natural-hair figures. No survey, percentage, or statistic appears anywhere on this page, because none of the ten guides provides one. The dated comparison is this page's own reading of those guides' own dates and numbers.
