01
Define the wearer and clothing underneath
Start a lab coat size specification with the intended wearer, fit direction and clothing worn underneath. Review the coat over the clothing planned for daily use and record that combination for the fitting session. Identify women's, men's or unisex versions and any separate lengths in your range. Keep the wearer's body measurements separate from finished garment measurements: an M label does not define the chest room, sleeve length or fit for a particular market.
02
Agree the garment measurement points
Use the same measurement method for the specification and every sample review. Mark the starting and ending points on a drawing or photo, choose one unit and record whether each value is a flat width or a circumference. Note the sample size, whether the coat is fastened and whether it has been washed. The table is a recording template, not a ready-made size chart. Agree target values and tolerances for your project before judging a sample; blank fields remain decisions to resolve.
| Point | Method to agree | Sample record |
|---|---|---|
| Chest width | Fasten the coat and agree the level below the armholes for a flat measurement across the body. | Target __ / measured __ / tolerance __ |
| Shoulder width | Mark the shoulder endpoints and agree how the back is laid out for the measurement. | Target __ / measured __ / tolerance __ |
| Body length | Choose the shoulder or center-back starting point and the exact hem endpoint; do not mix methods. | Target __ / measured __ / tolerance __ |
| Sleeve length | Mark the shoulder or center-back starting point, sleeve position and cuff endpoint. | Target __ / measured __ / tolerance __ |
| Cuff opening | Record the fastening position and whether the value is a flat opening or full circumference. | Target __ / measured __ / tolerance __ |
| Hem width | Agree the measuring level, coat fastening and treatment of any vents or overlapping panels. | Target __ / measured __ / tolerance __ |
03
Review movement with the coat fastened
Fit the sample over the agreed clothing and close the buttons or other fastening as intended. Check standing, sitting and reaching forward, then the arm movements relevant to the wearer's work. Note where pulling, restricted movement or unwanted opening occurs, and photograph the specific area with the review comment. Discuss the garment measurements and construction together before requesting a change. Review other required sizes separately; changing size alters several dimensions.
04
Check pockets, closures and logo placement together
Review pocket access while wearing the coat, not only while it lies on a table. List the items the pockets need to accommodate and record the usable opening, depth and position. Check whether reaching into a pocket affects the front fastening or nearby seams. Place the proposed logo at its intended dimensions on the sample and check its relationship to the chest pocket and lapel. Record placement separately for each length and fit.
05
Build a size-and-version quantity sheet
Count lab coats in pieces and give each style, length and logo version its own quantity line. For example, regular-length M coats with a shared school logo and regular-length M coats with individual names need distinguishable records, even if their garment measurements match. Add the garment color, size, number of pieces and packing group to each line, then reconcile the total. Keep proposed top-up quantities separate from the first order. This is an assortment plan; material availability, workable quantities and delivery timing are confirmed in the quotation.
06
Keep one sample review record for the approved version
Copy the fields below into your review notes. Compare the measured sample with the agreed chart and separate accepted details from changes still requested. If the sample uses substitute fabric or unfinished decoration, identify what remains to be reviewed. Consolidate comments into one dated revision before confirming the production reference. For a later batch, quote that version and list changes separately. You can begin a lab coat inquiry with a reference photo and the details you know; a completed specification is not required for the first conversation.
