Well, actually, it is!

I was taught this trick years ago----glad to see it works in "metricland"
also.

One finger width on a USA Sectional Chart 1:500,000 is (approximately) 5 NM
One Nautical Mile is (approximately) 6000 ft

So--at 30:1 (200 ft/mi), one finger is about 1000 ft required.
At 20:1(300 ft/mi), one finger is about 1500 ft required.

Add in pattern altitude, and there you are!
