How to tell the size of a toy?

Informative topic breakdown of Dildo Sizes:

Ladies- what size dildo do you prefer in relation to pre and post pregnancy??
I've wondered sometimes while writing my reviews how much having been pregnant and/or having a vaginal birth affects what type of dildos women prefer.

Attention Size Queens
Were you always a size queen? Or did something or someone make you change and become someone who likes a bigger than average size. Share in...

Are you a "size queen"?
I am personally not, but I have seen this term all over and I'm curious about the ratios!

maximum size!
I've been gone for a while, but I return with news! My maximum diameter i could take was 3. I have just moved up to 3.25 with The Cyclops. Anyone else

circumference is the area around the toy (the length of a string if you were to wrap it around it)and the diameter is the area across (measured at the widest point) if that helps.
If you're just starting and want something small maybe start with a 1 inch diameter? I have a 1 1/2 and its pretty girthy. It also depends on the material and if it has any texture. For example a jelly toy with a 1 1/2 inch diameter is going to be much more squishy and have a lot more give than a glass toy with the same measurements. Unfortunately in the end it's just trail and error to see what you like.

It can be either - whichever is easier for you. Circumference goes around the outside of a toy (like when you wrap your fingers around it), while diameter goes across it (draw a circle, then draw a line through the middle of that circle - that's the diameter). Eden measurements are generally given for the widest point in the toy's usable length.

I have heard that circumference tends to be a more accurate measurement for girth, but I wouldn't know how that works since I'm not mathematically inclined. I usually go by diameter since it's easier for me to imagine, and so far it's worked out fine for me.

Luckily, in addition to understanding the math, EdenFantasys has the ability to show you the actual size of the toy. Click the ruler-shaped graphic under the pictures of the toy. Then, hold up a real ruler, your credit card, or a dollar to your screen, and slide the calibrator to make it real size.

Then you can hold up your favorite toy to the picture of the toy on the screen, and find out which ones are comparable in size!

I also go by diameter (which is across the center of the toy) because it is easier for me to visualize. I can't use anything over a 1.25 diameter, personally, without really working up to it. Other people find that much too small!

To convert circumference to diameter, or vice versa, it's really easy! Circumference is diameter times pi, which is approximately 3.14. It's not exact, so it won't give you an exact answer. However, you can use a calculator like this one to solve for unknown quantities, and not have to do any math at all. Just plug in the circumference or diameter, and it will give you the measurements for the others.

Once you find out your ideal size, it's easy to look at the numbers and know immediately if it's a good toy for you.

Bex and Rin are right on the money. Here is a visual for you.


Something that might help with a future purchase, take a piece of string and wrap it around a toy that is too big. Where the string crosses itself make a mark on both pieces. Lay it out straight and measure the distance between the two marks, this will give you the circumference. Take that and divide it by 3.14 to get the diameter. Once you have either measurement you can look for something smaller.

I agree with Rin that circumference is the better measurement as not all toys are perfectly round. I am more of a diameter person due to my back ground in steel fabrication where all measurements are given in diameter.

ya I have issues with girth- Jopen makes amazing vibrators but after failing with the vr6 I studied the product pages where most toys have a "view actual product size" button right underneath the first main pic of the toy. The dimensions are really important. If a toy is to big or small for you, and its on eden go to the product page check the dimensions and then start adding or subtracting. thing is I find the best view of the toy is looking at it straight at the tip- the shape whether its round or square etc etc is important too. Trial and error will lead you to a toy you end up using as your guide. good luck!

actual size link......on the toy page

I love it when other users post pics with multiple toys next to each other. It's a really good way to compare the size of different products especially if you own at least one of them. I'm looking for differences in length and width.

Thanks for posting that pic!

I trust diameter.

thanks you for clearing it up....

Thanks everyone never knew about the size thing on the product page! Going to check that out know! You would think after being here for so long I would notice it. I guess I need to pay more attention. Thanks!
