Dear Sir,
I would love to know the size of your poster.

Also would like about your organisation, if the background could have related elements of your organisation for better output.

No bigger than 3x3 but format it to however looks best, whether it be square or rectangle so as close to 3x3 that looks good. The event is just a party for an organization that is going to be coachella themed so you can just copy the colors and the background as much as possible. Thanks!

What unit you mean about the size, 3x3 meters or else?
