What are the dimensions of the average sex toy?

Happy Monday! For your (reading) pleasure, here is a study in which the authors–whose last names, by the way, are Herbenick, Barnhart, Beavers (ahem), and Benge–measured the average size of sex toys sold on popular websites. The conclusion? The average sex toy has similar dimensions to the average penis. But the extremes? Well, maybe you should just read the table (below) yourself…

Vibrators and Other Sex Toys are Commonly Recommended to Patients, But Does Size Matter? Dimensions of Commonly Sold Products.

Vibrators and dildos are commonly used by women and men in the United States, and are increasingly recommended by clinicians. In addition, sex toys and various household objects are sometimes used for sexual stimulation in ways that pose health risks to their users. Data about the dimensions of such products may inform clinicians’ recommendations.
The purpose of the present study was to assess the sizes (length and circumference) of vibrators and dildos marketed for vaginal or anal insertion on websites that sell sexual enhancement products.
Eight websites that sell sexual enhancement products were identified for inclusion in the study. The dimensions of vaginal vibrators and dildos listed for sale on each website were noted, and descriptive data were calculated for each website.
Product length and circumference (mean, median, and range).
Popular sex toy distributers offer a variety of product sizes. The length of many vibrators and dildos was sized between 4 and 6 in, and circumference was between 4 and 5 in. However, some companies featured products of a considerably larger size than others.
Length and circumference of vibrators and dildos varied, but on average approximated mean penile dimensions. Clinicians’ recommendations for use of vaginal or anal products can be enhanced by familiarity and offering additional information about product sizes and retailers.”

    Add a carbide tip for cordless fine stone carving, metal graving, and glass marking. Paint chipping, not so much. Add bluetooth or WiFi: play music, Blue Man Group, Stomp, Taiko, Lissajous figures, Fourier sums, sonic beats; interesting take on phone calls and remote (symmetric) operation.

    I realize this is almost two years old, but it is something I never saw before. And I’ll take the age of the article into consideration.

    Before I comment, let me say that I have been in this industry as a multi-store owner for more than 25 years. That may not account for much, but I hope it does give me a little credibility.

    The part of the original article that concerned me was this statement “The average sex toy has similar dimensions to the average penis.” I am unable to agree with this statement.

    First, the average size of “vibrators and dildos” sold are LARGER than the average penis. With some customers, it is a real concern as they do not want to purchase a toy larger than the spouse in order not to infer to their partner that their equipment is lacking.

    Second, on the other side of the customer base, are those customers who are seeking larger toys. And this is the group that makes up the majority. Just in the rubber dongs category alone are items which are substantially “bigger than average”. In fact, I would have to really think hard about which ones could be considered “average”.

    It is also interesting to me that you chose to include products designed for anal use in the same category as vaginal regarding measurements. That is a very different area in terms of toy sizing.

    Thanks for the data. I’m glad to know that there are scientists out there looking at adult stores online and studying the products. Makes me feel good to think that sex toys are part of “scientific investigation”. It is what keeps this job interesting … and more main stream!
