Clothing size grading in Turkey: a buyer’s measurement and approval checklist

Separate body measurements from garment measurements

A body-size guide helps a customer choose a label size. A finished-garment specification tells the production team what to measure on the actual item. They are related but cannot be substituted for one another. State whether each number describes the wearer, the pattern or the garment after making and finishing.

Identify the target market, fit intention and reference garment. A relaxed sweatshirt and a close-fitting top can target the same wearer measurements while requiring different finished dimensions. Attach a dated photo or physical reference if the fit language could be interpreted in more than one way.

Define every point of measure

Give each measurement a code, a written method and a drawing that shows where the tape starts and ends. Record whether a garment lies flat, is measured around its circumference, is closed or open, and whether the fabric should be stretched. This prevents two teams from producing different numbers from the same garment.

For a top, the chart may include chest width, body length, shoulder width, sleeve length and opening dimensions. The relevant points depend on the style. List the approved unit of measure and an agreed tolerance for each point; do not assume one tolerance works for every seam or fabric.

• Measurement code and illustrated location
• Measurement method and units
• Finished measurement by size
• Agreed tolerance and approval status

Approve a base size before grading the range

Choose the size that will be used for the first fit decision and identify the wearer or fit model used to review it. Record comments against the sample number and product-file revision. A note such as ‘make it roomier’ should be translated into a changed measurement or construction instruction before the pattern is revised.

The approved base sample is a reference for fit, fabric behaviour and construction. It does not automatically prove that the smallest and largest sizes fit as intended. Decide which additional sizes need physical review for the product and size range before production begins.

Write the grade rules rather than relying on a size label

A grade rule specifies how each measurement changes between sizes. Give the intended increment or the full finished-measurement table for every offered size. Check the relationships between chest, waist, length, sleeve and openings; simply scaling every dimension by the same amount can change the garment's proportions.

Ask the pattern and sampling team to flag dimensions that cannot follow the proposed rule without altering the shape or function. For a set or layered garment, consider how pieces work together across the whole range. Keep size names, internal pattern sizes, retailer size codes and label artwork aligned in one controlled table.

Check fabric behaviour before releasing final measurements

Fabric construction, stretch, finishing and laundering can change how a garment measures or feels. Agree whether the measurement chart applies before or after any specified washing, pressing or finishing step. Review the actual proposed fabric against the fit sample, especially when a substitute material is introduced.

Record any required wash or dimensional-change test in the product brief and decide who will review the result. A fabric change or an altered finish may reopen fit and grade approval; otherwise the approved measurements can refer to a garment that will no longer be produced.

Keep the size breakdown separate from the grade table

The grade table describes what each size must measure. The order breakdown describes how many pieces of each size and colour to make. Send both, with matching size codes. For example, a change from size M to size L quantity should not silently alter the approved dimensions for either size.

Before production release, reconcile the purchase order, pattern names, label data, cutting plan and packing instructions against the same size list. Assign one person to approve any later size-range or quantity change, and record whether that change affects components or a production slot.

Send Konsey Textile a size-ready production brief

Konsey Textile's custom-clothing route starts from design documentation, reference garments and fit comments and includes pattern and sample development. For a size discussion, send the style drawing or tech pack, intended market and wearer, target fabric, base sample, measurement method, full size chart and the sizes you want sampled.

Ask the team to confirm the development route for your particular garment, the evidence needed for size approval and the point at which the approved pattern and measurement revision becomes the production reference. Quantities, timing and commercial terms should be confirmed against that specific brief.

Make the size approval record usable on the cutting floor

For a three-size top, record the finished chest, length and sleeve measurements for each size beside the approved sample revision. Add the measurement method, tolerance, fabric reference and sign-off date. If the buyer later changes the fabric, identify which measurements and sample sizes need fresh review before cutting.

• Base-size sample and fit approval
• Measurement chart and grading revision
• Other sizes selected for physical review
