Creating your design at the right size before you upload:
Make sure you switch on the rulers in Photoshop (Ctrl + R), Illustrator or any software you are using and ensure that your patterns/objects are the size you wish them to be printed.
You can check your design size in Photoshop by going onto Image>Image Size ( Ctrl + Alt + I)
Remember that once you upload the design, the size shown will be the largest size achievable at 150 DPI. Therefore a 20 cm x 20 cm file at 150 DPI will show at 20 cm x 20 cm. Whereas a 20 cm x 20 cm file at 300 DPI will show at 40 cm x 40 cm ( our clever software will scale it automatically). You can always make it smaller using our ’Change size’ tool to the right of the image
