Tips for Taking Measurements:

  • Take all measurements lying flat. Lay the T-shirt out on a flat surface. The front should be facing up. Hanging clothes can stretch as you measure and if you have them on a model of a different size this can skew your measurement.
  • Use a flexible tape measure at least 36″ long. Don’t try to take clothes measurements with standard 12″ ruler you’ll end up with an inaccurate measurement. If you have no tape measurement handy and this is somewhat of an emergency, you can always download a printable measuring tape online.
  • Measure twice! If you don’t get the same measurement both times try again.
  • Record measurement to the nearest 1/4 inch. Anything more specific is irrelevant but remember lying flat measurements are generally doubled (e.g. lying flat waist of 12.5″ can be understood as a 25″ waist) so a 1/4 inch could make a difference.
  • Take measurements when you’re taking photos. Trying to measure as your listing at your desk ends up taking a lot more time and energy moving back and forth between tasks.
  • Not all manufacturers make their clothes to the same specifications. Always check the size chart before you buy online.
