- What's better than the center of a circle? A spare car key without leaving home! I started Tom's Key Company (tomskey.com/?Tomah...) so you can get quick and affordable DIY spare car keys and fobs shipped to your front door.
See my favorite 3 ways to find the center of the circle. This is based on testing a dozen ways to find the center of a circle. (test video being published soon). These were all suggestions in comments from my original center of circle video: ( • How to Find the Center... ).
These three methods are all quite easy and quick. Check them out.

I would just trace around a piece of paper and then fold it twice.
Real quick!😂
This is the real answer right here 😂
These demonstrations are excellent! You made them so easy to follow and understand. Thanks for your effort and for sharing them. I really appreciate it.
How I love UA-cam for this very reason! Just doing some DIY projects and this helped tremendously. I’d like to vote for the second example lol seems easiest with less work and fastest. Great video 👍👍👍👍

I like the second. I never took geometry so my mind is blown on 2. Extremely useful, all i need to do is remember it in the future. Thank you.
I just came back to review your video. I cannot thank you enough! I really like the second chord method!
Pop through time-space into space-time, realize you are the circle, you are the center. Come back, share what you learned, get crucified. Take a nap, etc. Great video, very helpful and I love that you tried all the suggestions from the audience. A golden age of entertainment and education we live in.
Dude thats .... deep...... :) are you weaving hemp baskets all day long ??how do you even come up with this.. :)
Technically if you are the center of the universe and you place the circle exactly between your axes and a mirror draw a line across then rotate the circle at it axis 137.5 degrees in accordance to the fibonacci sequence then draw one more line you will have the center of the circle ....

here's a very simple solution: draw a straight line between any two points on the circle, find the line's center point and draw a line (again, from edge to edge) through that midpoint that is perpendicular to the original line. The new line is a diameter and its midpoint is the center of the circle.
Wow, that is really easy and precise.
@@joaovianna7321 thanks algebra
@Lance Bermudez No, this one involves drawing only two lines
@@zioxei His third chord in the video is superfluous. It only requires two. The third is a control to help mitigate stacking inaccuracies.
@@joeywatch1145 What you call the third line is actually the sixth line drawn. Lifulo is right
All the 3 ways are best . I liked the 2nd way the most. Thank u so much.
I always used the third method. Now I will use the 1st and especially the second method! Thanks for sharing Sir!
very informative and very easy instructions good video, i now have this in my memory bank Thanks
Your practical demonstration is much better than a drawing.
I like the second method the best. Thanks for sharing.
You are a very kind person my friend. Thanks for the video.
Wonderful tutorial. Great editing and video work. Now I know how to do this. Much Thanks.
I'm in the middle of a project, and this is a problem I'm facing soon. The 3 solutions you shared make sense, and doing this no longer seems so daunting. Thanks for your help.
Thanks for explaining and showing this with the paper or saying anything with a 90 degree angle. It sounds simple, but it seems like we forget all about angles of items and such when we need to remember. You explain things well and that means a lot coming from a special ed teacher.
You're very welcome! Happy to hear that
Excellent video. Thank You Sir!
Very cool! Thanks!
Perfect! Thank you and everyone else so much!
Thanks for the video! I love to see and compare clever ideas
awesome way for finding centre.
well done...
Example 2 is just what I need to re-find the center of my 20 foot round pool pad so I can do the final leveling. Thank you.
Awesome thanks! Now I can get back to my project. Number three is perfectly simple!
Thanks so much! 😊
Thank you, the third one is the fastest for me, out on the job and it is easy to carry the common sizes with me in 1/4 increments or something like that.
Super!! I loved third one.
Great video! I needed it!!
Just what I needed. Thanks, man.
The 3rd one works best for my project because I have 5 circles to find the center of. Thank you!
Very helpful video. Thank you.
Great ideas! Should have thought of that myself! Dauh!😉
Thank you for sharing. They were all useful.
The best way I know is to use a special square which touches right the extents of the circle. The square has another staff at exactly 45 degrees, and you mark on it a short line close to the center and turn the circle a bit and repeat. I believe this method was found by Euclid ages ago.
Yes, we made an engineers variant in school metalwork, c. 1972, UK.
Using 4 or 5 mm mild steel or brass sheet, make a three-quarter pie shape, with dead square cut out quarter, fix another (long, triangular is neatest) piece to it bisecting the 90 degrees, obviously at 45. We did this by 'secret rivetting' - the thing we were being assessed on. (Thank you Mr Payne).
You can use this to find the centre of a cylinder end or round bar too.
Good ideas here and useful if accuracy isn't paramount!
And yeah, get millimetres - but then you'll spell it wrongly!
My preferred method also. Any carpenter or woodworker has two squares, on of them with a 45. Just overlay the 2 squares and you have the tool to use the method you describe.
Awesome technique! Paper template seems easiest of the 3! Thx
You made my day man! Many, many thanks.
nice work - thanks for sharing!
Looking at a glance, square in the circle is my type thanks. Live and learn.
Thank you!
The 3rd method is the quickest and easiest, it's the one I always use. I'm not trying to impress anyone with needless geometry skills. Great infom on all 3.
The cord method is best for many contractors as that they will most likely have a Swanson speed square in their toolbelt. Although I myself am not a contractor, this is the method that I use for my DIY projects that require a center point in a round object, such as wood, metal, plastic, or even foamboard.
Number 3 is the best! Thanks
2nd method... you saved my day !!!
Thank you BOSS
Excellent video and a great process
Thanks bro for sharing this valuable knowledge on UA-cam.😊😊😊
the center of three lines trick is great!! thanks!!
Thank you so much
These are great. The template method is my fave
Saludos, excelente explicación. Me ha sido muy útil tu video!... Un abrazo desde Venezuela
Jorge Matheus,
Si, la explicacion es sencilla.
Espero que esta bien y con buena salud en Venezuela.
Saludos de California.
What a useful video. Thank you 👍
Thank you so much! I think I will be using the paper folding method. Been trying to figure this out for a while!
thank you men, your video helped me a lot.
I used the first one and it worked perfect for me. Thanks for the video
Thanks for Sharing! Have A Super Week!.....Gus
Nestle the circle into your framing square. Mark the two contact points on the circle and square. Rotate the square so the marks line up but the angle of the square is inside the circle. The sides of the square are radii and they meet at the center of the circle. You can use the measurements on the square instead of marking anything if you prefer. Just line up the measurements on the square with the edge of the circle for the same result.
Instructions unclear. What does "Rotate the square so the marks line up but the angle of the square is inside the circle" mean? Do you mean flip the square?
I measure from a outside point of the circle and find the largest measurement to find the diameter. Mark it then repeat in a different spot. Where they intersect is the center. You can do three to check your center.
I like this method!! Thanks for sharing!!
Thank you so much!! Cheers :)
Perfect! Helped me with my project!
Nicely done!
Excellent, thanks!
Very cool
Hey - thanks for your video - I'll use the last method now!
Excellent methods. Ty for this
Glad it was helpful!
Person suggesting the third method comments "MUCH easier" - method takes by far the longest. Great. Thanks for the upper case MUCH.
Perfect. I'm getting ready to make spinning tops. I don't want them to wobble. The paper template idea is perfect.
Have fun!
thank you, thank you. It helped me a lot.
Cutting holes in the ends of a water drum to make a tumbling composter, this helped a lot, thanks, probably use the second method.
Glad it helped!
I just used the fold method for a large lazy susan build........It worked out great ...thanks!!!
Thanks man , good vid
Thank you! I will use this
Thanks man! I used the chords method to make a turn table from wood
Good teaching! Thanks
Glad it was helpful!
Thanks ,you where so helpful for mr me, Never to late to learn you just showed me that I thankyou
awesome tip....
Take sheet of paper that's shorter then the circles diameter, fold the paper perfectly in half and crease it good. Now unfold the paper and set it so both bottom corners exactly touch the outside of the circle, mark a little dot on the circle at the end of the crease toward the outside edge of the circle, do the same on the other end towards the center. Line those two dots up with a ruler and draw a line. Turn the circle 120 degrees or so, doesn't have to be perfect, and repeat the dots and line again with the creased paper, where those two lines intersect is the exact dead on balls center.
Thanks for the video. Of the three, I believe the first was my favorite, however if not having marks on your project is a factor, then the last would be the one.
Thanks so much. All are great, but 3rd Method has me laughing at its simple but brilliant cleverness! Kind Regards.
number 3 is the best method
thanks dud
Love the template method!
Thank you! Cheers!
I always use the third method. It is much easy. I sew to sell and sometimes I fold the fabric circle and iron it to find the centre of my circle.
Thanks for sharing!
I was taught to use a compass set at the radius and draw two arcs in the centre and where they cross you’ll find the centre. Something like that, it’s been over 50 years since I was taught this in geometry class.
Thank you so much!!!
Nice video, thanks so much
🙌 Thank you so much! The paper template is perfect for me! I'm creating an art piece and can't put any obvious marks on the wood I'm using. ☮💜
Wonderful! Thank you so much for watching!
Great video.
Very useful information, better than just entertainment channels.
Wedge the circle in the square, combine a framing square 45 on the inside and draw a line through the center . Rotate the circle and draw another.
Good useful info. Thanks for making video
So nice of you, thank you!
Really easy and awesome
wonderful I used the last one. So easy 🙂 Thank You
You're welcome 😊
The last one works perfectly especially for plates!
Genius 🤩 Thanks for sharing. As well as to the smart contributors 🏆
Happy to help!
Using your ideas, I moved a ruler up and down near the center line to find the widest point, took that measurement, and drew a line. I then did another cross line of the same length. The intersection was the center.
It's very good, living and learning.
I like the second way. It can be done with the straight edge of a piece of paper, cut to length of chord and fold in half for center and use 90° corner or strike arcs from points that are equal distance from both sides of center that are longer than that distance, strike them over centerline. Where they intersect will connect to centerline perpendicular to chord. If you have the space, strike arcs from each end of chord that are longer than half the length of chord. Strike them on both sides of chord. Connect the two points of intersection, through the chord. That line segment will be perpendicular to chord AND divide it in half. Maybe a combination of methods 2 and 3 where you lay it out and make a template, but using more geometry and less origami.. Lol great tricks. All three have their merit.
1st way was definitely easier
I love you!! Thank you so much! I was having a hard time.
Glad I could help!
Thank you!!!
the Chord method is nice...I learned something new today, Thanks!!!
I recently had to find the center of about 20 wood circles. I had cut a 2" dowel into 20 segments and wanted to drill a hole in the center of each. In Photoshop I created a 2 inch circle with 2 90 degree radii (crosshair) and printed it out. I cut out the circle, placed it over the dowel, held it up to a light to make sure it was centered, and poked through the crosshair into the dowel with an awl.
Thank you 😊
Built log homes 10+ years. Use torpedo and draw verticle down side 4,5, or 6 inches whatever works as long as it easily divides in two. Mark center of that line and use level to draw horizontal line threw it. Measure it and mark at halfway. Use level to draw verticle center line. You have center of log, and the needed vertical and horizontal center point of log. This is for anti-symmetrical handcrafted logs, turned logs are much easier.
