Absolutely - you can place the order in cm or inch size for any delivery country. Gelato will then handle this complexity for you to convert and fulfill the order locally.
For example: When your customer buys a poster, frame, or framed poster in cm for delivery to North America, we will convert the order to the closest inch size. Order will then be shipped locally. The same applies to the opposite case too (inches to cm).
You can find all the sizes we offer, including the equivalent size both in centimeters and inches on the product page in the product catalog (see example below).
Important: Some sizes such as the iso A-formats don't have an exact equivalent(i.e. with the same aspect ratio) in inches, which means that if an order for e.g. an A4 poster is sent to the US, this is automatically converted to 8x12 inches format which doesn't have the same aspect ratio, with consequent cropping on the design. We recommend leaving some allowance around the edges of your designs to prevent essential design elements from being cropped off during conversion.
