To ensure your "stick" [Yardstick] is perfectly straight up and down drill a small hole in the tip of the yardstick and tie a piece of Paracord through the hole using a knot to prevent it from slipping out. Then cut the length of the paracord to the desired length and tie a stainless steel nut to that end. When you hold the stick at arm's length you can adjust the angle using Gravity to bring the nut alongside the stick. Viola! 90 degrees!
Sure glad this works, it's the same method I use when I put the wife on the tractor to pull on a tree so I can make sure the tree doesn't damage the tractor by landing on it.
I’ve been using a similar method for estimating how far the top of the tree will land from the stump. No stick required. Hold your arm straight out like you were doing, but bend your forearm up 90 degrees at the elbow. Now distance yourself from the tree to the point where your elbow is at the bottom of the tree and your fingertips are at the top. Now turn your forearm level to the ground. Your fingertips are where the top of the tree will land. It’s pretty accurate and quick.
mind you, that' just the distance from the stump that the top of the tree will land. getting it to land there still requires being able to cut accurately.
@@rickeykeeton4770 first, because there is no firearm involved. second, because your elbow stays at the base of the tree. and you have to have a really fast cutting saw to cu a tree down and have the top of the tree land at the base fo the tree. or cut the tree from the top. and another way he could have said it is to rotate your arm so your elbow remains at the base of the tree and your forearm is parallel to the ground. that shows you were the tree will fall if it goes in the direction you expect it to.
You could also put a bowl of water down on the ground and when you can see the very top of the trees reflection in that bowl of water you are exactly 💯 on brother!
Ha! You've reminded me of my Forestry Instructor demonstrating this method many years ago: after getting the stick to the correct length, he'd say "you then put one end of the stick up to your remaining good eye..." :-)
Another way is to walk out a random distance away, hold a stick vertical at arms length, shorten it to the hight of the tree (I've not been able to stretch them longer, so you might need bigger stick). Then rotate it horizontal. With one end at the base of the tree the other end will fall on a spot the height away from the tree. I like the 45 degree method you showed us, but I use this method to quickly see if I fall a tree to the side how far it will reach. You can measure how far that spot is if curious, but knowing what it's going to hit is usually more important.
Great humor! It made the video. Based on the comments I don’t think most folks appreciated it (or understood it) but it was awesome! And the method is cool too
Good information to know. I'm going to go over to the neighbor's from lawn and try it. To check the accuracy I'll cut down the tree and actually measure it. Of course I'll wait til they're not home to do this.
Presents! / Charity work! ❤️ ❤️ ❤️ such a caring neighbor let’s em know “you’re watching” …out for his place …making sure it doesn’t run away while he’s gone wink Everybody loves a surprise! Like that Navy Seal and his wife jumping on his back “I yelled SURPRISE DAMNIT!?” Specially when they get back home. I’m lol ing the hell out of this post
Simpler way. Mark the tree from the ground up to a known height. Say 5 feet. Mark that place on the tree. Back up a distance and use the tape. Hold your tape vertical at arms length and measure the height of the 5 foot measurement on your tape. Then measure the height of the tree on your vertical tape. If say the 5' mark measured 1 inch on your tape and the tree measured 20 inches, multiply 5 x 20 and the tree is 100 feet tall.
Loved the funny antics and humor. I have used this method for 50 + yrs and it is very effective. I wear nothing but Merino wool socks-wonderful for your feet. Great illustration for me a diagram would be great too
You forgot to mention, if you are standing below the stump [in elevation], then you subtract from overall distance. If you are standing above, then add to the distance. Good video.
Glad I seen this video.. my method I came up with on the spot was: use the stick exactly as you did, then tilt the stick over to see where the top would likely go.. trying to measure a Oak to make sure it's not going to crush a shed when I drop it. Will be double-checking with this method. I don't need to know the actual height in feet, just whether that height will reach a particular point so I assume a string will suffice in place of the measuring tape as the longest one I've got is 25'
I used a helium balloon on a string. My neighbor looked confused. I used the string then to measure the distance to the Corvette in his driveway. He understood and moved it into the garage.
I was thinking I might do that at some point. I just need to find a good candidate that I want to cut down that is not in some steep nasty place that would make it hard to do that kind of a video. I already cut most of those ones down before I even thought about doing this video.
I use a clinometer and an app I created in Excel. I mean yes I know that if you walk to a point where the top of the tree is at 45 degrees, the tree is the distance to the tree plus the distance from the ground to your eye level, but it isn't always possible to walk to a convenient point where you can still see the tree.
Alternatively, you can use a protractor and plumb bob to measure the angle of elevation between the base and top of the tree then multiply the tangent of that angle by your distance from the tree. Add the height of your eyes above the ground to be exact.
Wow, 125 feet is 38 meters. Here in the norwegian woods that's pretty high! (Everything in the US is so BIG!) The tallest tree i've felled here were 110 feet, and that had grown so tall in a deep valley. Your hightmeasure was exellent performed, but works only on a flat terrain. More difficult to measure a tree in a steep slope, then you really have to use your brains.... or pure experience!
Awesome! Thank you! My trees are on a slope, not on a flat. I cannot walk away from the tree on a straight line while remaining at level with the bottom of the tree. How would this method work in my situation?
Years ago, my brother went to the woods with a coworker to cut some trees for firewood. My brother told his coworker that he should move his pickup so the tree wouldn't fall on it. The coworker said not to worry, the tree wasn't that tall. When the tree came down, it hit the pickup. Sometimes trees are longer than they are tall. Best to keep that in mind when estimating the height.

Very useful. Thank you , for uploading. I had a flashback to my geometry teacher talking about the French army using their hat and steps to measure the distance( rivers).

A 45 degree right triangle, what we call a SPEED SQUARE, is likewise going to indicate the same distance in height as you would measure across the ground .
I learned this back in FFA in middle school. BUT that was a lot of years ago so I had forgotten all the steps to do. Thank you for reminding me of how it was done an how many yearssssssss ago that was . LOL THANKS
I had to remove rotting short tree, no measuring, placed stick on ground where I planned top to land. It passed stick about 1-2 feet not bad for eyeballing
Place a mark 6 ft. high on the tree with a ribbon or cut mark. Walk back and hold up a ruler at arms length, eyeball measure the base of the tree to your 6 ft. mark on the tree and the eyeball height of the tree. Use a simple math ratio to estimate the height of the tree = measured height of tree /measured base to ribbon X 6 ft.
In the OSU Extension "Master Woodland Manager" course, we had a field training day devoted to finding height/volume using a Forester's "Woodland stick" with all sorts of nifty calculations imprinted thereon. They can be had by searching for forestry equipment, if one is so inclined... (Sorry. Ok, not sorry.) I use the old, trusty, thumb in-line-of-sight: "Oh, 'bout 60 feet, or so..." Another installment of Wilson's Useful Tips; akin to Red Green's oft quoted: "If they can't find you handsome, at least they'll find you handy." Cheers from your less inclined neighbour to the North.
If you were to look close at that fancy yardstick I had. It says Master Woodland Manager on it and it has those nifty imprinted calculations. I went through the Master Woodland Manager program with my dad when I was a kid in the 80s. That’s where it came from.
I did that with my middle school students. Ratio of the shadow of a yard stick. Then measure the tree's shadow. Doesn't work very well on a cloudy day. lol

Huh, try doing this is the temperate or tropical rain forest :-). Here in BC, there is no way you can see the top of the tree, as there ar so many trees around. Anyhow in clear conditions, I guess this works well.
MY dad and I dropped 3 - 90 ft trees in a 10foot wide alley a month ago... one of his friends said they are about 45 ft tall... I said not quite... walked off until I got about a 45deg angle from my eye to the tree top... paced it off and said DOUBLE IT, it's more like 90 ft.
Similar triangles. There's a fable in the history of mathematics that relates how Thales many centuries ago measured the height of the pyramids at Giza using this technique.
How about doing it in the forest (deep forest).... Good luck. I have trees over 150 ft tall in 6 acres of thick forest, but the only way I can measure them is with a drone (even thought that's not too accurate).
Our local water company passes them out at the county fair, about the only place one can find such a utensil. I guess it's not as effective of advertising as it used to be since most kids don't know how to use one.
I don't want to be that guy but... I'm going to: yes, they are isosceles triangles because two of their sides have the same measure, and this makes things easier to measure as the ratio is 1:1 between both, but you are actually taking advantage of similar right angle triangles. Sorry for being that guy.
Does this assume your feet and the base of the tree are on the same plane, level ground, not hilly? Seems like it would be really hard to do on hillsides.
Wait, at 5:12 eye level how do you measure? All sounds good but without a demo at eye level we’re all blind. Got the trunk up gig, but the other way of measuring is how? Measure eye level then add the eye level to trunk math?

I think I'll start slowly by telling them "I'm watching you and everything you do". They'll sleep better that way.
Funny. And how tall was the tree? And this my friends is why almost everybody has a Ring camera.
Thanks for the heads up! I'll wear a mask.
Simpler way. Mark the tree from the ground up to a known height. Say 5 feet. Mark that place on the tree. Back up a distance and use the tape. Hold your tape vertical at arms length and measure the height of the 5 foot measurement on your tape. Then measure the height of the tree on your vertical tape. If say the 5' mark measured 1 inch on your tape and the tree measured 20 inches, multiply 5 x 20 and the tree is 100 feet tall.
Even simpler: 1) Cut tree down; 2) measure felled tree.
Just have your wife climb the tree and lower the tape down! How hard is that!
@@richardpark3054 After the tree has been felled it's not as tall.
@@RazorStrap But it's hella wider!

Old school, but it works. Been using this method for years. Helps to avoid hitting stuff when I’m working in close quarters.
It helps me know where to put my stunt camera so the tree won’t hit it. 😁
You forgot to mention, if you are standing below the stump [in elevation], then you subtract from overall distance. If you are standing above, then add to the distance. Good video.
Trig for trees. Love it! Who knew maths were important in the woods. Great channel. Keep up the great work!
I like this guy's humor and his method for finding how high the tree is.
You're a hoot, Wilson. Sure glad you found a "thing", it must have been close to a "round about".
This is an OLD way but good way. I learned this in high school in the 70's. We all measured the flagpole in front of the school.

I used a helium balloon on a string. My neighbor looked confused. I used the string then to measure the distance to the Corvette in his driveway. He understood and moved it into the garage.
Yup, it works. Is Part 2 felling the tree to see if it hits the 'X'???

Great video, I appreciate the subtle humor.
great method ... if you are on flat ground. Never been in a forest that was that flat.
What a great application of similar triangles!
I use a clinometer and an app I created in Excel. I mean yes I know that if you walk to a point where the top of the tree is at 45 degrees, the tree is the distance to the tree plus the distance from the ground to your eye level, but it isn't always possible to walk to a convenient point where you can still see the tree.
Great video! I was going to use a laser pointer and a protractor. This seems easier!
45 degrees. distance is same on each side. Like your method. Thumbs up!
Sadder but wiser; I did the backwards crab walk and fell into a gopher hole. You were right to advise against it.
Alternatively, you can use a protractor and plumb bob to measure the angle of elevation between the base and top of the tree then multiply the tangent of that angle by your distance from the tree. Add the height of your eyes above the ground to be exact.
Seems simpler than the stick method.
I got some camel city mills merino wool socks. Happy with them. Good cushion
Great simple method. Will try it on my giant pines. Thank you.
straight talking no nonsense as usual keep up good work,
This is helpful to estimate where the top of tree will land when you cut it down.

Thank you for the information... and your dry humor. I don't know why TH-cam led me to this video, but I'm sure glad it did!
At 2:00 the stick doesn’t need to be at 90 degrees to your arm. But it does need to be plumb or vertical, which is easier to determine.

Don’t forget to add in the distance from your horizontal arm to the ground.
Thanks teacher ,reminds me of my third grade teacher with yard stick
My third grade teacher used a yardstick, too; for a paddle on naughty children.
Place a mark 6 ft. high on the tree with a ribbon or cut mark. Walk back and hold up a ruler at arms length, eyeball measure the base of the tree to your 6 ft. mark on the tree and the eyeball height of the tree. Use a simple math ratio to estimate the height of the tree = measured height of tree /measured base to ribbon X 6 ft.
It's called a Biltmore stick, used them in my forestry classes a lifetime ago.

Great information!! Thanks for sharing!! Stay Hydrated and Have a Safe Day
Can you put a link in so I can find one of those fancy sticks with the lines on it ?
Triangles with equal angles are relative sizes.11 am to 1 pm lets you compare height of stick to tree ht
Back in school, we were taught how to use a shadow to calculate the height of the tree.
I did that with my middle school students. Ratio of the shadow of a yard stick. Then measure the tree's shadow. Doesn't work very well on a cloudy day. lol
Thank you , you didn't touch on the technical name for this technique .
where do the sticks come from? i need some delivered so i can measure my trees.
I use the same method I find it works close enough to fell the tree.

Those socks look great too!
It also allows you to estimate where the tree is going to land. 😀
How about doing it in the forest (deep forest).... Good luck. I have trees over 150 ft tall in 6 acres of thick forest, but the only way I can measure them is with a drone (even thought that's not too accurate).
Yardstick?? Guard that treasure with your life. Literally they dont make yard sticks any longer.
Our local water company passes them out at the county fair, about the only place one can find such a utensil. I guess it's not as effective of advertising as it used to be since most kids don't know how to use one.
Tractor Supply has them for a buck and a half. Likely Lowe’s, Home Depo, Ace ect as well. 👍🏼
Well, I got your joke, even if it is a groaner.
Oh.... Bad.
Of course they don't make them ANY LONGER. If they did, it wouldn't be a YARDstick...
@lpeterman Yep, if you add a little bit, then it's a meterstick instead of a yardstick.
I reckon there were bears sat down In the background with a bag of berries saying....this guy knows his trigonometry.
He could have measured the distance to the bears, too. If he had a bearometer.
Doesn’t this method assume that the ground where you’re standing away from the tree is flat/level with the base of the tree?
use the app on your phone to find 45 degrees or simpler yet fly a drone to top of tree and read the height on your phone.
Good Idea. And hold a straight stick on to your phone to get a more accurate sight line.
Are you Red Green's boy? Thanks for the handy tip!
Why not just slide the stick up or down to match the tree?
I don't want to be that guy but... I'm going to: yes, they are isosceles triangles because two of their sides have the same measure, and this makes things easier to measure as the ratio is 1:1 between both, but you are actually taking advantage of similar right angle triangles.

Height can be measured using a piece of paper, a pencil, a baseball, etc.
