It is possible to get a print with bigger dimensions - here's the details:

We offer several sizes. It all depends on the size you have already ordered. If you contact [email protected] with the order number, for more information, customer service will help.

You can also find the sizes we offer here on the help page of the website: https://thenightsky.gorgias.help/en-US/what-are-the-print-dimensions-22876

If you have placed an order but it hasn't yet been submitted to the print queue there's still time to change the size in your order confirmation email, or if you prefer, contact customer service at [email protected]

Hope this helps!
