Resolution to Scale Question

I’m working on surveying my property and one of the planners I’m working with asked for a map with scale of 1" = 200’ and a 5’ CI – I understand (roughly) how to do that in QGIS, but is there a standard resolution I should be using to get precision at this scale? Trying to determine the highest possible height I’ll be able to fly at to achieve this.

Someone may have the numbers and the calculations at their finger tips better than I do, but if I remember correctly, at 300dpi (assuming printing), a 5cm pixel would give you 1:200 scale. This would mean, for e.g. a 12MP DJI Mavic Pro, you could fly at 220m and get the adequate resolution.

In most countries, your max height without a waiver is 120m (in the US, it is 400 feet in Class G airspace). So, in short, flying at your maximum legal height, you will probably get higher resolution than you need.
