In Flexitive, we provide a wide variety of Fixed and Responsive sizes to make it easy for you to create the designs you need. You can find a complete list of sizes available in Flexitive in our support article on What Sizes are Available in Flexitive.
In addition to the default sizes, you can also add custom sizes to your Flexitive instance.
If there is a size you would like to permanently remove from your Flexitive instance, please contact firstname.lastname@example.org, and we will be happy to help you with removing the size. Removing a size from an instance can take up to 1 business day to complete.
