Here are the correct answers -

Diameter is the length of a straight line through the center of an object (such as a circle).

Circumference is the complete distance around the outside of a circle.

Thank you for your participation!

Have you come across reviews that have it switched?

I have found some.

I much prefer to see the circumference of the shaft of a toy in a review. it's much easier to visualize.

Really? I prefer diameter, I guess it's just opinion.

I usually try to include both so I can make sure everyone knows regardless of their preference

I think there are some specs even in metric system.

Ros,

Is there a prize for the correct answer ?

@charmedtomeetyou: Oh yes, I've seen this happened in some of the most recent reviews, and that is why I started this thread. I hope EFers who are uncertain of the definitions for those two words will get it right from now on.

@Edeneve: Like Lioncub, I prefer to see both -- especially when the actual measurements differ from what are listed on the product pages.

Well, now I have to go back and check my review and see if I did it properly. Mine I measured and not went by the specs.

"I think there are some specs even in metric system."

Cool, thank you for sharing this information with us even though it is off-topic.

My high school required passing trig. and calc. to graduate. The concepts of diameter and circumference are so introductory in math that I couldn't imagine confusing the two.

I prefer to see circumference specs myself. Diameter doesn't always tell you what the circumference will be, it just gives you a size range. For example, a dildo that has a diameter of 1 1/2 inches will have a circumference that's anywhere from 4 1/2 to 5 inches. I prefer to know the exact circumference.

Well, if the dildo is actually circular, the circumference will be 4.71238898 (and on) inches.

I prefer diameters. The way that people measure circumferences fails with flatter dildos.

Great post, I doubt the people in question are the ones on the forum but it never hurts to try.

I use the product page for this information. I completely skip the part of a review that talks about size. I know what I like and what I don't like and I can glean this from reading the product page when it comes to this specific information.

How does measuring the circumference fail on a flatter dildo? It seems like that would be the case for diameter.

The diameter tells me the maximum width of the toy, whereas the circumference would give me no warning that the dildo might be very wide.

Honestly, I prefer seeing both, but if I had to pick one, diameter would win.

I thought EF measured the circumference at the largest part of the dildo, am I mistaken? I'm not trying to debate you or anything, I'm just curious.

Here's what I think: let's say there are two dildos, both measure 1.5" in diameter at their widest section, the first dildo is completely rounded and it measures 4.71" in circumference; the second one is flatter in shape even at its widest section, so the circumference should be smaller than the one with the rounded contour -- am I making sense?

Psh, I'm not trying to talk the world into my point. I'm just expressing my opinion, and all are free to disagree.


I feel like bringing out an example to better illustrate my point.

Dildo A: A perfectly circular dildo with a diameter of 1.5", which gives it a circumference of 4.71".

Dildo B: A dildo that is in the shape of a perfect ellipse (oval) with a long axis width (biggest part of the diameter) of 2" and a short axis width of .5" (smallest part of the diameter). Granted, this is a very strange shape for a dildo, but for the purpose of this example it will do. This dildo will have a circumference of 4.58".

Dildo B seems smaller than Dildo A, but, in reality, more users will find its 2" much more difficult to insert than the simple 1.5" of dildo A. Likewise, somebody that prefers larger dildos would probably skip over dildo B despite it filling them more (at least, in a stretchy way).

This issue becomes more complicated if an object you're measuring is partly concave. It becomes ridiculous when you consider that measuring the circumference depends on how precisely you're doing it.

Thanks, Stormy!

I also like to check the product page for information first, but occasionally the size information for a certain item is simply insufficient on the product page (I know it's the manufacturer's fault), e.g. the double-ended So Dildo -- only the smaller end's measurements are listed.

The product dimensions are provided by the manufacturer. EF employees do not handle toys outside of the packaging -- unless it's Ilya taking photographs for the product pages. (Those toys then find a home in the corner of his office.)

This is very true. It really does depend on the manufacturer. Again, for me, size really isn't an issue until we get over 6" in circumference. If it's thicker than a coke can, then we have problems. LOL

Okay, I understand what you're talking about now. You explanation is very good. I love the example you used, I got a clear picture of what you were talking about and now I understand how the shape of the dildo can affect the circumference. Thanks for providing this example!

on many occasions I have found some info on the product page to differ from my own info, i.e., measurements. that's why I've always written a thorough review instead of relying on the product page.

As evidenced in other posts on this thread, the differences are due to where you measure the toy. Manufacturers will pick the widest or the thinnest part to measure for their info.

I've had toys that were shorter or longer than what the manufacturer provided too, so it's not just a matter of where it's measured. There often is an actual difference.
