I am not too sure where to post this? MOD’S - please move if better elsewhere - thanks.
I have made a large oak “picture frame” or “photo booth” for a wedding (to match other wedding things I have made for this couple) which needs to be hung from a frame that is self supported and easily assembled by unknown staff of unknown intelligence and at an unknown wedding venue. The picture frame is made form 3/4 inch oak, to be hung from pine handrail by chain.
The attached image shows the concept.

The posts are 2m /79” tall and the top horizontal beam is the same wide.
I do not know the formula/ratio to work out how long/wide/heavy the base needs to be in order to accommodate this, i.e.: to stop the poles falling over. I intend to have the poles (handrail) slip into pre cut holes in laminated MDF by 12.5 cm/5”. The wedding venue will not allow sinking poles into lawn or to hang the frame anywhere, hence the need for this base - but how long/wide/heavy do I make it - any help in this calculation is gratefully received as it is a long time ago since I studied physics!
Thanks and kind regards, John
