Find the Center of a Circle (3 EASY and QUICK Ways)
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.

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.
I would just trace around a piece of paper and then fold it twice.
Real quick!😂
I just came back to review your video. I cannot thank you enough! I really like the second chord method!
How I love KZhead 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.
very informative and very easy instructions good video, i now have this in my memory bank Thanks
All the 3 ways are best . I liked the 2nd way the most. Thank u so much.
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 ....

I always used the third method. Now I will use the 1st and especially the second method! Thanks for sharing Sir!
Wonderful tutorial. Great editing and video work. Now I know how to do this. Much Thanks.
I like the second method the best. Thanks for sharing.
You are a very kind person my friend. Thanks for the video.
Thanks for the video! I love to see and compare clever ideas
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
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.
Awesome thanks! Now I can get back to my project. Number three is perfectly simple!
Perfect! Thank you and everyone else so much!
Looking at a glance, square in the circle is my type thanks. Live and learn.
Awesome technique! Paper template seems easiest of the 3! Thx
Excellent video. Thank You Sir!
The 3rd one works best for my project because I have 5 circles to find the center of. 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!
Great ideas! Should have thought of that myself! Dauh!😉
awesome way for finding centre. well done...
Thanks bro for sharing this valuable knowledge on KZhead.😊😊😊
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
You made my day man! Many, many thanks.
Just what I needed. Thanks, man.
I used the first one and it worked perfect for me. Thanks for the video
Thank you for sharing. They were all useful.
2nd method... you saved my day !!! Thank you BOSS
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.
thank you men, your video helped me a lot.
the Chord method is nice...I learned something new today, Thanks!!!
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.
These are great. The template method is my fave
Very cool! Thanks!
Thanks ,you where so helpful for mr me, Never to late to learn you just showed me that I thankyou
Excellent video and a great process
the center of three lines trick is great!! thanks!!
Number 3 is the best! Thanks
Very useful information, better than just entertainment channels.
Thanks for Sharing! Have A Super Week!.....Gus
nice work - thanks for sharing!
Thanks so much! 😊
thank you, thank you. It helped me a lot.
Hey - thanks for your video - I'll use the last method now!
Super!! I loved third one.
Great video! I needed it!!
Thanks so much. All are great, but 3rd Method has me laughing at its simple but brilliant cleverness! Kind Regards.
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 👍
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.
Perfect. I'm getting ready to make spinning tops. I don't want them to wobble. The paper template idea is perfect.
Have fun!
Awesome video! I love how you took everybody’s comments and suggestions, tested them all out and found the best solutions, along with shouting out each contributor. THIS is how the internet/KZhead should be, showcasing the best of everybody’s collective ideas, not just one person showing everyone how THEY think it should be done.
Very helpful video. Thank you.
I just used the fold method for a large lazy susan build........It worked out great ...thanks!!!
wonderful I used the last one. So easy 🙂 Thank You
You're welcome 😊
I love you!! Thank you so much! I was having a hard time.
Glad I could help!
The last one works perfectly especially for plates!
Thanks man! I used the chords method to make a turn table from wood
Thank you so much!! Cheers :)
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.
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.
Perfect! Helped me with my project!
Genius 🤩 Thanks for sharing. As well as to the smart contributors 🏆
Happy to help!
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?
number 3 is the best method thanks dud
Excellent methods. Ty for this
Glad it was helpful!
Good useful info. Thanks for making video
So nice of you, thank you!
Awesome video much more accurate then eyeballing it. Saves for next time.
Thanks man , good vid
Nicely done!
Thank you so much
EXCELENT!!! THANKS FOR SHARING . GO AHEAD
Good teaching! Thanks
Glad it was helpful!
Very nice, Thank you. It would of been cool to drill holes in each and compare how close the methods are to each other.
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.
Person suggesting the third method comments "MUCH easier" - method takes by far the longest. Great. Thanks for the upper case 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!
Love the template method!
Thank you! Cheers!
Thank you! I will use this
This video deserves a thousand likes
Second option was the easiest for me thanks
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!
Excellent, thanks!
I like the last sample. Good for those who has limitted tools at home
thump up from me for number 3 I had a knife and paper within reach when I watched the video - so in a few seconds I had a dot on the middle of my circle ( a round plastic cap that I'm making into a wheel for an rc model plane. Thank you.
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.
Great! very good! Simple and not stupid .......very unusual for uploaded videos usually
Thank you so much!!!
Nice video, thanks so much
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 very much for you trick.
Very cool
It's very good, living and learning.
Second method suits me, thanks for sharing
You're welcome 😊
Thanks! I like the Last one best.
Which one is more practical for on the job use like the electrical circles on ceiling when putting on soffet
Last method is clean ..easy can be used for future circles
