Customizer Help
Tips and Tricks that we hope will make using our Customizer fun, enjoyable, and the final product meeting your expectations.
Image Size & Negative Space
Our recommendation for image sizes are 12 to 13 inches wide by no more than 15 to 16 inches high, as the product allows. 12 inches in width is pretty much the standard for adult shirts and 10 inches wide are standard for youth shirts, with the height being proportional.
When placing your design onto a product, be more mindful of the image size than how the design size looks on the mockup. Not all mockups are of a certain size, for example some clothing mockups might use a medium shirt instead of an X-Large. Pay closer attention to the actual size of your design. The max image boundaries are preset by the Customizer.
Measurements are indicated above your design when you scale it, as highlighted in the image. It indicates the width and height of the image, including any negative space. It's W (left) x H (right). Width is the far left number and Height is the number that follows to the right.
Before uploading your image, we recommend that you remove (Crop) as much negative space around your design as possible to get the maximum use of product space and your design should be closer to your intended size.
Uploading Art
As mentioned earlier, we recommend that you remove (Crop) as much negative space around your design as possible to get a more accurate use of product space.
When uploading art, please take note of the max file size, acceptable file formats, and the design requirements per type of product you will be customizing. Knowing these requirements will make your use of the Customizer more enjoyable.
Acceptable file formats are PNG, JPG, GIF, SVG, AI, and CDR. Max file sizes are 10MB with a minimum resolution of 200dpi for clothing and a minimum resolution of 400dpi for accessories. The resolution will determine the sharpness and clarity of your design.
File formats are important. Your design should be isolated (transparent) from the background (shirt, mug, or other product). JPG files are not transparent. PNG and GIF files can be transparent, but GIFs do not scale as well as PNGs. Both formats must be made transparent prior to uploading. SVG, AI, & CDR files are vector not rasterized, hence the cleanest files that can be used. The drawback is the Customizer only recognizes them as one color. A multicolored SVG, AI, or CDR file will be uploaded as one image, but can be changed to any of the colors offered in the Customizer.
