Downloading in A1 , A2 & other A-series Sizes
To print in any A-series paper size, you need to resize your blocks. The Poster, Report and Flyer templates allow you to change the size for all the blocks when you change the size of one block. You should toggle on 'Download As Blocks' when downloading (especially to separate multiple pages).
Before downloading, there are 2 options to prepare your pages to be downloaded in an A-series (A0-A10) paper size:
To print in any A-series paper size, first, choose the size as the block size.
Download the visual at the highest quality. Then when printing, choose the paper size desired and use the "fit to page" option. Since the ratio is the same, it will fit perfectly!
Option 2: Use custom dimensions
Using the block settings, you can set a custom size equal to the paper size, such as for A1: 24 inches x 33.1 inches.
Be sure to hit the return key after you have entered both dimensions.
The maximum width for the custom block settings: 40 inches, 101.6 cm, 3840 px.
