Im very need it Figmateam, hope you will read this section. 

Adding another +1 for this feature. Just created an entire deck template, and came back to create a different format version, and … nothing.

Figma please! Don’t make me use Canva…

Can't believe FIGMA SLIDE can’t custom size slide. It's easy choice for must-have feature. Im building a system presentation on SLIDE, and consider which platform can easily customize.

Please figma! custom canvas dimensions for slides.

Figma we need custom size please!! 

Standards like : 8.5x11, 11x17 for print!

And even for mobile: vertical aspect ratios would be rad!

+1 vote for this feature! absolutely need it and also we need the PDF export to not be just a simple image put in a page.

I followed the recommendation made by the design studio creating my branding to go with Figma for our slides, as they designed our new design system within Figma.
Now that they delivered everything, I’m discovering that our deck template doesn’t fo full screen on most desktop devices and I can’t change the deck’s size.
I feel scammed. How is this not a feature?!

I 473rd this most basic of requests.

+1 … Yeah this is a must if our team is to transition over to Figma for decks. So many scenarios where portrait is needed.
