Bodice measurements
Bust, waist, front length, back length, shoulder, neckline, and armhole settings control the upper portion.
Sewing pattern guide
Dress measurements guide
A dress draft combines bodice and skirt logic. The waist connection is the key area where upper and lower measurements must balance.
A basic dress combines two drafting problems in one garment: a bodice that must fit the bust, shoulders, and armholes, and a skirt that must clear the hips — joined at a waistline where every error from above and below meets. The dress generator drafts the front and back pieces directly from your measurements, positions the bust and waist darts from your bust point values, and checks that the sewn seam lengths match, so the quality of the tape work decides the quality of the block.
This guide covers all ten measurements the generator asks for: the four circumferences and ease, the vertical lengths that set bodice balance, the shoulder and armhole values, and the two bust point measurements that most people have never taken before. Each one has a precise landmark on the body, and each one controls a specific area of the draft.
You will need a flexible tape measure, a piece of narrow elastic to mark the natural waist, and a mirror or a helper — the back length and bust point height are genuinely hard to take alone. Wear the bra you plan to wear with the dress: bust, bust point distance, and bust point height all change with a different bra, and the darts are drafted from exactly these values.

Generator
Basic dress pattern
Build a connected bodice and skirt draft with waist, darts, length, and hem checks.
GeneratorBasic bodice pattern
Draft a bodice block with neckline, armhole, shoulder, length, and waist shaping.
GeneratorBasic skirt pattern
Generate a skirt block with waist, hip, darts, side seams, and silhouette presets.
Waist connection
The bodice waist and skirt waist must sew together cleanly after darts and shaping are considered.
Hip and skirt length
Hip and length control the lower block. They affect room, movement, and the visual proportion of the dress.
Classic, fitted, or A-line
Silhouette presets change side seams, ease, and hem shape. Each should be checked with the intended fabric.
Darts across sections
Darts in the bodice and skirt must create a clean transition rather than fighting each other at the waist.
Hem and movement
Dress hem allowance and skirt width should match the planned finish and walking comfort.
Before cutting fabric
After generating a dress, verify bodice balance, waistline connection, skirt side seams, darts, hem, seam allowance, and print scale before cutting fabric.
Step by step
How to take each measurement
Tie the waist elastic first and find the high shoulder point — the small bump where the base of the neck meets the shoulder seam line. Almost every vertical measurement starts or ends at one of these two landmarks. Enter all values in centimetres.
-
01
Bust, waist, and hips
Measure the bust horizontally around the fullest point, wearing the intended bra, with the tape level front and back — a tape that drops between the shoulder blades understates the value by 2–3 cm. Measure the waist where the elastic settles, snug but not compressing. Measure the hips around the fullest part of the seat, usually 18–23 cm below the waist. These three circumferences plus ease set the entire horizontal fit of the dress.
-
02
Front length and back length
Both run from the high shoulder point at the base of the neck down to the waist elastic — the front length over the bust, the back length straight down the back. Take them separately rather than assuming they match: a full bust typically makes the front 2–5 cm longer than the back, and this difference is exactly what the generator uses to balance the bodice so the waist seam sits level instead of riding up in front.
-
03
Shoulder width and armhole depth
Shoulder width goes from the high shoulder point to the shoulder bone where a set-in sleeve seam should sit — usually 11–13 cm. For armhole depth, measure from the high shoulder point vertically down to the level of the underarm crease; a practical method is to clamp a ruler horizontally under the arm and measure down to its upper edge. Too shallow an armhole binds; too deep restricts arm movement and gapes when sleeveless.
-
04
Bust point distance
Measure horizontally between the two bust apexes — the fullest points, at nipple level in the bra you will wear. Typical values are 17–21 cm. This value places the front waist dart: the dart must point directly at the apex, and a distance taken 2 cm off puts the dart on the wrong side of the bust curve, which shows as diagonal pull lines no amount of pressing removes.
-
05
Bust point height
Measure from the high shoulder point diagonally down to the bust apex on the same side, over the curve of the bust — typically 24–30 cm. Together with the distance, this positions the apex on the pattern and sets where the side-bust dart aims and how long both darts are drafted. It changes noticeably with bra choice, so re-take it if you switch bras.
-
06
Skirt length from waist
From the waist elastic at the side, measure down over the hip to the desired hem, wearing shoes of the intended heel height. The generator joins this to the bodice to form the continuous front and back dress pieces and adds the hem allowance separately, so enter the finished visible length. Knee level is usually 55–60 cm from the natural waist; midi around 70–78 cm.
-
07
Sanity-check the set before generating
Before entering the values, check the internal logic: front length should exceed back length for anyone with a defined bust; bust point height should be several centimetres shorter than the front length; half the bust point distance must be smaller than a quarter of the bust. If one of these fails, one measurement is wrong — find it now, not after printing.
Typical measurement ranges
Use these EU reference combinations to sanity-check readings, not to replace them. A generated dress drafted from real values will beat any chart — the chart only tells you when a number looks implausible, such as a bust point height of 40 cm or a back length of 32 cm on an adult.
| Reference size | Bust (cm) | Waist (cm) | Hips (cm) |
|---|---|---|---|
| EU 36 | 82–86 | 64–68 | 90–94 |
| EU 38 | 86–90 | 68–72 | 94–98 |
| EU 40 | 90–94 | 72–77 | 98–102 |
| EU 42 | 94–99 | 77–82 | 102–106 |
| EU 44 | 99–104 | 82–88 | 106–111 |
| EU 46 | 104–110 | 88–94 | 111–116 |
Front length typically runs 42–47 cm and back length 39–43 cm across these sizes, with the front 2–5 cm longer. If your bust and hips fall in different chart rows — the most common reason ready-made dresses fail — enter your real values and let the draft absorb the difference in the darts and side seams.
Common measuring mistakes
Measuring the bust without the intended bra
A different bra shifts the apex position and the bust circumference by several centimetres at once. Since the generator drafts both bust darts from the apex values, measuring in one bra and wearing another moves the darts off target. Measure in the bra the dress will actually be worn with.
Letting the tape drop at the back bust
The tape must stay level all the way around at the fullest bust level. Dropping toward the waist at the back is the classic error — it understates the bust by 2–3 cm and produces a bodice that strains across the front. Check the level in a mirror from the side.
Guessing the back length
The back length is nearly impossible to take accurately on yourself; guessing it from the front length breaks the bodice balance, and the waist seam tilts. Ask someone to measure from the prominent bone at the base of the back neck down to the elastic, or use a well-fitting garment as reference.
Measuring shoulder width to the sleeve seam of a shirt
The shoulder seam of whatever you are wearing rarely sits on the actual shoulder bone — dropped shoulders add 2–4 cm. Find the bone at the top of the arm by raising and lowering the arm and feeling for the joint, and measure to that point.
Adding ease into the measurements
Entering 96 cm for a 92 cm bust 'to be safe' stacks your allowance on top of the generator's ease, producing a dress one size too big with darts in the wrong places. Enter raw body values; the ease field is the only place to add room.
Skipping the bust point measurements
Leaving the preset apex values untouched while changing the bust circumference is the most common source of misplaced darts. The two bust point values take one minute with a mirror and are the difference between darts that shape the bust and darts that fight it.
From measurements to a dress that fits
Bust point position and dart behaviour
The generator ends both front darts a few centimetres short of the apex you defined — sewing a dart all the way to the point creates a cone instead of a curve. If a first muslin shows drag lines radiating from the bust, re-check the apex values before anything else: a dart aimed 2 cm off the true apex causes more visible problems than a bust circumference that is 2 cm off.
Bodice and skirt joined at the waist
Because the front and back pieces are continuous from shoulder to hem, the waist seam you would sew in a two-part dress becomes a shaped waistline inside the pattern. The bodice and skirt dart intakes are matched at this line so shaping flows through it. If you later split the pattern to add a waist seam, cut along the marked waist guide and add seam allowance to both new edges.
Neckline shape versus depth
The six neckline shapes — round, high round, scoop, V, square, boat — redraw the curve, while neckline depth moves its lowest point. A V-neck deeper than about 18–20 cm from the high shoulder point tends to gape over a full bust unless the fabric is stable or the edge is reinforced; a boat neckline needs almost no depth but a wider opening. Choose shape first, then adjust depth in small 1–2 cm steps.
Ease, shaping level, and checking the draft
For a woven dress, 4–6 cm of bust ease is a classic fit and 6–10 cm a relaxed one; soft, regular, or strong waist shaping controls how much of the waist difference the darts absorb. After generating, read the construction checks the generator reports — it compares front and back shoulder lengths and the complete side seams with the bust dart closed, to a 3 mm tolerance. Then print at 100%, confirm the 5 × 5 cm test square, and sew a quick muslin of at least the bodice.
Frequently asked questions
Why does the generator need separate front and back lengths?
Because the bust makes the front of the body longer than the back. Drafting both sides to one length forces the waistline up at the front and creates folds above the back waist. The measured difference — usually 2–5 cm — is built directly into the balance of the front and back pieces.
What exactly are bust point distance and height used for?
They locate the bust apex on the pattern. The distance is measured horizontally between the two apexes; the height from the high shoulder point down to the apex. The generator aims the front waist dart and the side-bust dart at this location and sets their lengths, so these two values control where the shaping actually lands on your body.
Does the generated dress include a sleeve or a closure?
No. You choose an armhole direction — set-in sleeve, sleeveless, or relaxed — and the generator reports the finished armhole length so you can draft or match a sleeve to it. Closures, facings, and lining are added according to your design; the pattern includes seam and hem allowances as the dashed cutting line.
Can I use a stretch fabric with the dress block?
The draft assumes a woven, so for a stable stretch woven you can reduce the ease by roughly the fabric's give — down to 2–3 cm at the bust. For true knits like jersey, a dress needs a different drafting logic with smaller or negative ease and shallower darts, so treat the woven block only as a starting shape and test in muslin.
Which dress measurement should I double-check before printing?
Armhole depth. Circumferences are easy to verify and lengths show up quickly in a muslin, but an armhole drafted 2 cm too deep gapes when sleeveless and restricts arm lift with a sleeve — and deepening or raising an armhole after cutting is one of the harder corrections. Re-measure it with the ruler-under-the-arm method, and confirm the test square measures exactly 5 × 5 cm before cutting anything.
