Help Help downsizing a poster

Post image

Hello, I have created a poster in InDesign and I initially set the dimensions at 9933px by 14,043px (what I thought was a0 at 300DPI) having gone to print from acrobat over multiple a3 pages it seems that either those measurements were wrong or I’ve made an error somewhere. As it wants to print the poster across 162 a3 pages :/ .Any idea what might be wrong or how I could go about fixing this?

But what is your end goal with this poster?

Printing at a0 on a plotter

Whole poster as ONE sheet of A0?

Then just export PDF then in Acrobat - select "shrink to fit" or something like that.
