Size and Fit Guide for Custom Garments
A practical guide for planning custom garment sizes, variants, fit samples, and approval-ready specs before suppliers quote.
Choose teamwear sizes from the measurements and fit of the specific garment being ordered. A familiar S, M or L label from another brand is not enough to approve a new size run.
Distinguish body measurements from garment measurements
A body-measurement chart describes the wearer. A garment-measurement chart describes the finished item, sometimes measured flat. Check which chart you have before comparing numbers. A flat chest width and a chest circumference are different measurements and cannot be compared directly.
Make the measurement method repeatable
Ask for the product’s measurement diagram and record the units, measurement points and whether the fabric should be relaxed or stretched. Use the same method for every sample. Do not invent a manufacturing tolerance: ask what tolerance applies to the quoted product and which measurements it covers.
| Item to check | What to record before approval |
|---|---|
| Chest or body width | Measurement points and whether the value is flat width or circumference |
| Body length | Starting point, hem endpoint and relevant fit preference |
| Sleeve or inseam | The product-specific measurement method |
| Intended use | Movement, layers worn underneath and any protective equipment |
| Size range | Available product sizes and separately specified youth or adult variants |
| Variation | Supplier-confirmed tolerances and what will be checked on the sample |
Approve a sample and then the size allocation
Where available, use a sample or size set for fitting before collecting final selections. Check movement and layering in conditions relevant to the sport or workplace. Note issues against the exact product and size rather than recording a general “fits well” comment.
Personalization can make corrections more involved, so verify the roster’s sizes, names and numbers together. A 3D preview helps review artwork placement; it does not confirm physical fit, comfort or fabric behavior.
Keep fit records for reorders
Retain the approved chart version, sample reference, measurement method and size allocation. Recheck these if the product, material or construction changes. Ask MerchandAise to review unsupported fit or construction requests before assuming they can be produced; structural changes require separate feasibility review.
How to use this custom garment size guide
Use these checks before approving a custom merchandise quote, supplier shortlist, or repeat-order program.
Size-run planning
Separate youth, adult, men, women, and unisex needs before asking suppliers to price apparel.
Fit sample decisions
Decide whether fit samples, previous garments, or measurement charts are needed before approving production.
Variant and reorder control
Retain color, cut, fabric, decoration and size details as a starting point. Ask which specifications can be repeated and check a new sample or proof when the product changes.

Size and Fit Guide for Custom Garments FAQ
What size details should a custom garment brief include?
Include quantity by size, youth/adult split, preferred fit, gender or unisex variants, color, fabric, decoration method, logo placement, and any sample or measurement requirements.
Do custom garments need fit samples?
Fit samples are useful when the order is high volume, size-sensitive, or new to the buyer. They reduce approval risk before full production starts.
