Ready for the job.
Start with the size chart for your exact product. Use this guide to take measurements, understand the chart and allow room for your workday layers.
How to measure ↓Match the measurement type
Confirm whether the chart lists body measurements, flat garment widths or garment circumferences. Compare like with like.
Consider your layers
Think about what you will wear underneath and how you move at work. If you are between sizes or unsure, contact us before ordering.
Body measurements ≠ garment measurements.
01 / Measure your body
Use this method only when the product chart asks for body measurements. Use a flexible tape and keep it level, without pulling it tight.
- Chest: measure around the fullest part of your chest, under your arms.
- Waist: measure around your natural waist, or the position specified by the chart.
- Hips: measure around the fullest part of your hips if required for the garment.
- Height: stand straight without shoes and measure from the floor to the top of your head.
Do not compare your full body chest measurement directly with a chart labeled “1/2 chest” or “chest width.”
02 / Measure a garment flat
Lay a similar, well-fitting garment flat, fasten closures and smooth it without stretching. Follow the product chart’s measuring points.
- A — Chest width: measure straight across between the underarm points. This is a flat width, not a full circumference.
- B — Length: use the starting point specified in the chart, such as the high shoulder point or center back neck, and measure to the hem.
- C — Shoulder: measure across the shoulder seam points where applicable.
- D — Sleeve: follow the chart’s start point. Shoulder-to-cuff and center-back-to-cuff measurements are different.

Inches or centimeters?
1 inch = 2.54 centimeters. Convert the measurement, then compare it with the same measurement type in the product chart. This tool converts units; it does not recommend a clothing size.
Results rounded to 2 decimal places.
Common fit questions.
Should I always order one size larger?
No. Some styles already include room for layering. Compare the product’s garment measurements with a similar garment worn over your intended layers, and contact us if you are unsure.
What if I am between sizes?
Check all relevant measurements and consider the cut, movement and layers you need. Send us the product link and your measurements for guidance; do not rely on chest alone.
Are men’s, women’s and unisex sizes interchangeable?
No. Cuts and proportions can differ. Use the chart for the exact style instead of converting by the size letter alone.
How should I size a team or custom logo order?
Collect measurements for each wearer and confirm the size breakdown before ordering. Discuss sample availability, cost and timing before approving a larger or decorated order.
What if the item does not fit?
For orders from fonirra.com, review the return policy and contact us before sending anything back. Confirm the applicable terms for customized orders before production.
