If you can view it from a distance and it has some space to the side, simply take a stick, stand a distance away from the tree, whilst looking at the tree hold the stick in your field of vision till it matches the height of the tree then tip the stick over as if the tree was being felled, note the point on the ground where the top of the stick ends up and pace it out 👍 no idea about apps if that's what you need, sorry.

Similar method I guess but I usually use a rake handle, line up to my eye and the height of tree, and then pace out the distance between me and the tree.

Can't really imagine a phone app working that well unless you're up 200 feet and use an altimeter. Maybe though it can be measuring the angle up to the tip? If you type in distance that would give an estimate.

Unless you are an orangutan this wont work.  🙂   

 

The stick needs to be the same length as the distance from you shoulder to your knuckles for the trigonometry to works out. 

 I use the same method though for measuring heights.  But i use a disto to measure to the tree rather than pacing as a measure a lot of tree so need it to be quick.

I do have pretty long arms but not that long, luckily with the cunning of a fox I hold the rake part way along.

I was once told if you walk away from the tree bending forward looking between your legs back at the tree that when you’re at a distance that you can see the top of the tree, that distance will be height of tree! I guess there are many variables there but it would make me a happy man if there was any truth in it[emoji846]

I'm not that supple, so stick to the arm length stick and walk backwards to get height.

Dear Sirs, Great  discussion happening here.

I'm aware of the stick method but good to hear the various versions and arm lengths.

I have used apps before, sometimes with fair accuracy and other times right off the map.  I had to ask in case i was missing out on some jew of a free app that others were using but It might be too good to be true.

Really appreciate ye coming out!*

Buy a cheap laser measurer offline (one of the hunting scope type not the bosch household things) Plenty of calculators online. Measure from where you are stood to the base then to the top. You know the angle of the trunk is ~90 degrees so you can work it out

a sunnto clinometer is fairly cheap and easy to use
