Once installed, you'll find the add-on under "Extensions". Click to open it, and you'll see the sizes in the sidebar. Just click to resize. Screenshots below!
After installing the add-on, you can resize to standard sizes for free. No signup, no payment.
However, to use the 'premium' features such as custom sizes, custom margins, and non-standard larger sizes, you can upgrade to premium. To do that, just click the buttons on this page - either a one-off lifetime purchase, or a monthly subscription.
Most of the features are completely free to use. Just install it, and start resizing.
For more advanced features, you can upgrade to the Premium paid version for a small fee of $4.99/month or $29.95 one-time lifetime subscription.
Free: Resize to all standard KDP sizes.
Paid: Resize to non-standard KDP larger sizes; resize to your own custom size; set your own custom mragins.
You can see screenshots below, or on the add-on page here. Or, you can just install it and try it out for yourself.
First up - thank you! We really appreciate your support.
If you've paid for the premium version, there's nothing else you need to do. Our system will register your email address as having paid. As long as you're logged in with that email address (in the Google Doc) you're editing, it will link up and give you access to the premium features.
You can install the add-on completely free here and start using it in 20 seconds.
Optionally, you can upgrade to the paid version (via the links on this website) to use premium features.
