I would just trace around a piece of paper and then fold it twice.

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 KZfaq 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.

Your practical demonstration is much better than a drawing.

I always used the third method. Now I will use the 1st and especially the second method! Thanks for sharing Sir!

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.

All the 3 ways are best . I liked the 2nd way the most. Thank u so much.

very informative and very easy instructions good video, i now have this in my memory bank Thanks

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.

Wonderful tutorial. Great editing and video work. Now I know how to do this. Much Thanks.

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 are a very kind person my friend. Thanks for the video.

Awesome thanks! Now I can get back to my project. Number three is perfectly simple!

I like the second method the best. Thanks for sharing.

The 3rd one works best for my project because I have 5 circles to find the center of. Thank you!

Thanks for the video! I love to see and compare clever ideas

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.

Perfect! Thank you and everyone else so much!

Thank you so much! I think I will be using the paper folding method. Been trying to figure this out for a while!

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.

Excellent video. Thank You Sir!

Awesome technique! Paper template seems easiest of the 3! Thx

Looking at a glance, square in the circle is my type thanks. Live and learn.

Person suggesting the third method comments "MUCH easier" - method takes by far the longest. Great. Thanks for the upper case MUCH.

Thanks bro for sharing this valuable knowledge on KZfaq.😊😊😊

I used the first one and it worked perfect for me. Thanks for the video

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.

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.

Very cool! Thanks!

awesome way for finding centre. well done...

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.

Great ideas! Should have thought of that myself! Dauh!😉

2nd method... you saved my day !!! Thank you BOSS

Perfect. I'm getting ready to make spinning tops. I don't want them to wobble. The paper template idea is perfect.

thank you men, your video helped me a lot.

You made my day man! Many, many thanks.

Just what I needed. Thanks, man.

Thank you for sharing. They were all useful.

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.

Hey - thanks for your video - I'll use the last method now!

Thanks so much! 😊

These are great. The template method is my fave

I just used the fold method for a large lazy susan build........It worked out great ...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.

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.

the center of three lines trick is great!! thanks!!

Saludos, excelente explicación. Me ha sido muy útil tu video!... Un abrazo desde Venezuela

Thanks ,you where so helpful for mr me, Never to late to learn you just showed me that I thankyou

thank you, thank you. It helped me a lot.

the Chord method is nice...I learned something new today, Thanks!!!

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.

Excellent video and a great process

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/KZfaq should be, showcasing the best of everybody’s collective ideas, not just one person showing everyone how THEY think it should be done.

Genius 🤩 Thanks for sharing. As well as to the smart contributors 🏆

Thank you so much

Thank you!

Thanks so much. All are great, but 3rd Method has me laughing at its simple but brilliant cleverness! Kind Regards.

What a useful video. Thank you 👍

Very helpful video. Thank you.

nice work - thanks for sharing!

Thanks man! I used the chords method to make a turn table from wood

The last one works perfectly especially for plates!

Very useful information, better than just entertainment channels.

Number 3 is the best! Thanks

number 3 is the best method thanks dud

Thank you so much!! Cheers :)

Thanks man , good vid

Super!! I loved third one.

Cutting holes in the ends of a water drum to make a tumbling composter, this helped a lot, thanks, probably use the second method.

Perfect! Helped me with my project!

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.

Thanks for Sharing! Have A Super Week!.....Gus

Very cool

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! 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. ☮💜

Great video! I needed it!!

wonderful I used the last one. So easy 🙂 Thank You

My circle is less then two inches and it has to be right on the money. Paper template is the way to go! Thanks for the easy method!!

Excellent methods. Ty for this

Thank you so much!!!

I love you!! Thank you so much! I was having a hard time.

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.

Awesome video much more accurate then eyeballing it. Saves for next time.

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.

Excellent, thanks!

I like the last sample. Good for those who has limitted tools at home

It's very good, living and learning.

Thank you! I will use this

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.

Very nice, Thank you. It would of been cool to drill holes in each and compare how close the methods are to each other.

👏 thank you very much for you trick.

Nicely done!

Nice video, thanks so much

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.

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.

Good useful info. Thanks for making video

I figured out two ways to do this just now by thinking about it. Use a compass, open it to what appears to be a decent amount wider than what the center of a circle would be, set 1 compass point at the outer perimeter of the circle, they carefully draw an arc. Do that at 2 more points afterward. They look for the co-created convex shapes created, draw a line joining them, and you have center. Another way is to box the circle in with a framing square. Go in a linear perimeter by drawing upper right, then upper left, then lower left, then lower right (or whichever direction you wish so long as you keep right angles). Then simply connect the 4 box corners.
