General Sizing Guide

Fireforce Ventures makes every effort to provide the most accurate measurements possible, particularly for the garments we sell. However, given the fact that we sell everything from East German surplus to new production Rhodesian uniforms, there are some pretty wild differences in sizing. From our experience, shopping and trying to find the best fitting uniform when there are confusing NATO, EU, or Eastern Bloc sizes be listed can be quite confusing. For this reason, all of our products are individually and painstakingly measured for the best possible fit once they arrive. 

For our hats, any measured in metric sizes (measured in centimeters, generally in the 58-62 cm range) measure for circumference, and any measured in imperial sizes (measured in inches, generally in the 6 & 3/4-7 inch range) measure for diameter. We generally list or convert the hats back to imperial sizes on the product description for the sake of simplicity.

For our pants and trousers, the sizing is simple and will be generally based off the most accurate possible waist/inseam size that the pant would fit, without a heck of a lot of variation unlike some modern clothing manufacturers. What you'd measure around your own waist or down the inside of your leg with a measuring tape is exactly what you will get from the pants you order.

For our many of our field shirts or BDU shirts, it becomes a bit trickier with varying lengths, and military designations all differing by country. We keep it simple, either in noting one of two variations:

  • Actual body measurements: what you measure around your chest or across your shoulders is exactly what you get with a product.
  • Based on garment measurements: a measurement of the garment itself, laid out flat and measured across the entirety of the chest, shoulders, and when applicable from the top of the collar to the very bottom of the shirt.
Whenever garment measurements for chest size are noted, we measure the full length of the actual garment across the chest at the armpit seam.  they do we make note of this in the sizing guide of the product description. In terms of garment length, we measure from the top of the collar when folded down, to the bottom most point in the shirt. After extensive measurements of uniform shirts, we've found the best following approximations for the lengths that would best fit specific heights and chest sizes, especially for NATO standardized clothing:

Chest Fit

Height and Length

Extra Small: 34-36 inch chest fit, garment measures 38 inches across chest

Extra Short: 5’5-5-7 height, garment measures 25 inches from collar stitch to bottom

Small: 36-38 inch chest fit, garment measures 42 inches across chest

Short: 5’6-5’8 height, garment measures 27 inches from collar stitch to bottom

Medium: 38-40 inch chest fit, garment measures 46 inches across chest

Regular: 5’9-5’11 height, garment measures 29 inches from collar stitch to bottom

Large: 40-42 inch chest fit, garment measures 50 inches across chest

Long: 6’0-6’2 height, garment measures 31 inches from collar stitch to bottom

Extra Large: 42-44 inch chest fit, garment measures 54 inches across chest

Extra Long: 6’1-6’3 height, garment measures 33 inches from collar stitch to bottom

Extra Extra Large: 44-46 inch chest fit, garment measures 58 inches across chest

Extra Extra Long: 6’3-6’5+ height, garment measures 35 inches from collar stitch to bottom



Sizing military garments can be tricky, so we make every effort to standardize the messy business of sizing to this guide as much as possible. A tape measure is your best friend to ensure that you get the best possible fit out of a piece of clothing we sell, whether it's old surplus or new production.
