A poorly taken measurement is more expensive than a poorly cut pattern. The pattern can be adjusted. The measurement error will be invisible until the client tries on the garment — and by then you are remaking it at your own expense.
This guide covers every measurement a tailor needs for complete garment work, how to take each one accurately, the most common mistakes, and how to store measurements so they are accessible and permanent. Whether you are making agbada and senator suits or evening gowns, the principles are the same.
Before You Start: The Right Equipment and Environment
You need one good cloth tape measure — not a metal one. Check it regularly: tape measures stretch with use and a stretched tape will give you consistently wrong measurements without any obvious sign that something is wrong. Replace your tape measure once a year if you measure frequently.
The client should be wearing fitted underlayers — not baggy clothing, not heavy outerwear. Taking measurements over a thick sweater and then making a suit will result in a suit that does not fit when worn normally. If the garment is being made to be worn over specific undergarments (a formal bra, a waist trainer), those should be worn during measurement.
Ask the client to stand naturally, with their weight evenly distributed. People often tense up when being measured — ask them to relax their shoulders and breathe normally. A measurement taken while someone is holding their stomach in or puffing their chest out will not match their natural body when they are wearing the finished garment.
Upper Body Measurements
Chest / Bust
Measure around the fullest part of the chest, keeping the tape parallel to the ground. For women, this is typically across the apex of the bust. The tape should be snug but not tight — you should be able to slide one finger underneath comfortably. Record this measurement as the starting point for all bodice work.
Waist
The natural waist is the narrowest part of the torso — usually about 2–3 fingers above the navel. This is not the same as where trousers typically sit. Ask the client to hold their arms slightly away from their body. Measure around the natural waist, keeping the tape parallel to the ground. This is one of the measurements that varies most between individuals — do not estimate it.
Hips
Measure around the fullest part of the hips and seat, usually 7–9 inches below the natural waist. Keep the tape parallel to the ground. For African garments like wrapper styles and ankara skirts, this measurement is particularly critical — hip ease is what determines comfort of movement.
Shoulder Width
Measure from the edge of one shoulder to the edge of the other, across the back. The end point is where the shoulder seam of a well-fitted garment would naturally sit — at the outermost point before the arm begins. This measurement controls whether a garment looks balanced or like the shoulders are being pulled in either direction.
Across Back
Measure horizontally across the back, from armhole to armhole, midway between the shoulder and the waist. This is different from shoulder width and controls how much room there is for movement across the upper back.
Sleeve Length
Ask the client to bend their arm slightly. Measure from the shoulder point, over the elbow, to the wrist bone. For different garment types, you may need the measurement to the elbow only (for three-quarter sleeves) or to the knuckle (for formal shirts that show cuff). Record all three if you work across multiple garment types.
Lower Body Measurements
Trouser Waist
This is typically different from the natural waist — it is where the client actually wears their trousers. Ask them to point to where their trousers usually sit. Measure at that point. Recording both the natural waist and the trouser waist prevents the confusion that causes many ill-fitting trousers.
Hip (Seat)
Already covered above, but for trousers specifically, ensure you are measuring the fullest point of the seat rather than just the side hip measurement. For male clients especially, the seat measurement is frequently overlooked and produces trousers that are too tight across the bottom.
Inseam
Measure from the crotch seam to the desired trouser length. For formal trousers with a break, ask the client what kind of break they prefer (no break, slight break, full break) — this affects the finished length. Record both the inseam to the ankle bone and the desired finished length.
Crotch Depth
Ask the client to sit on a flat, hard chair. Measure from the natural waist down to the seat of the chair. This measurement directly controls trouser rise — too little crotch depth produces trousers that pull and restrict. This is the measurement that most tailors miss and that accounts for a significant proportion of poorly fitting trousers.
Thigh
Measure around the fullest part of the upper thigh. For fitted styles or for clients with larger thighs relative to their waist, this measurement prevents the garment being designed for the waist but impossible to pull over the leg.
The Most Common Measurement Mistakes
Experience shows that the same errors come up repeatedly:
- Measuring too tightly. Many tailors were trained that snug measurements are more accurate. They are not — they produce garments with no ease. Unless you are drafting with specific ease allowances already, a snug tape will give you a garment that feels constricting.
- Not recording the unit. Is that 96 centimetres or 96 inches? (96 inches would be eight feet.) Always note whether your measurements are in cm or inches. Tailora's measurement system has a unit field precisely because this error causes real problems.
- Measuring only once. For important measurements — particularly chest, hip, and crotch depth — take the measurement twice. If the two readings differ, take a third and use the median.
- Not noting the client's fit preferences. A measurement tells you the body. It does not tell you whether the client likes things fitted or relaxed, whether they find high armholes comfortable or restrictive, whether they prefer a long rise or a low one. These preferences should be recorded alongside the measurements as fit notes.
Storing Measurements So They Are Never Lost
The traditional method — a paper book with client measurements — has an obvious failure point. It gets damaged, lost, or becomes unreadable over time. A measurement book that goes back five years and covers 200 clients is irreplaceable if it is destroyed.
Digital storage is not optional for a serious tailoring business in 2026. Every client's measurements should be in a system that is:
- Searchable by client name
- Accessible from your phone without internet (or with minimal data)
- Backed up automatically
- Linked to the client's order history so you can see what garments were made and what adjustments were required
Tailora stores all of this. Each client has a measurement profile with over 40 fields, fit notes, and a complete order history. When a returning client orders a new garment, every measurement is instantly available without searching through a book.
