Tonight I installed a photo / protractor program on my phone and had some fun with the 100' tape measure. My results were similar to what I calculate by putting my 4' tall kid next to a tree and using a photo editor.

For height I'm listing the range of measurements I get using any method. Width I figure I'm within a foot on.

My old Shingle oak comes in 94' to 109' tall and about 105' wide at two spots.

My "big" to me Metasequoia from Arborday in November 2003 is between 37' & 42' tall about almost a perfect 36' circle.

Interestingly the Ogon I planted Sept 2009 is already between 27' & 31' tall. Its comparatively thin @ 18' wide with them long upswept branches. So much for slower growing because of yellow foliage. The big tree was considerably larger in 2012 when we had the drought so maybe that set it back more?

I also have a 78' wide white ash.

The Cornus controversa from the spring of 2010 is 20 foot near circle wide. It might be fifteen feet tall, I didn't measure that lol.

My neighbor's short fat burr oak gave me a measurement of only 95'. I swear I got wider before. Maybe I picked the wrong angle or maybe having the six year old help wasn't the best of ideas.

The most frustrating thing about this is my old Note2 has about a 4 degree error calculating tilt which was apparent measuring across the basement that I couldn't calibrate out of it. Amazingly that 4 degrees was apparent from the moment I fired up the program on my phone. I already had a jig worked out for calibrating my telescope's laser collimator so it was easy enough to confirm.
