There are multiple reasons why anyone will want to know about dildo sizes. It could be that they once chose the wrong size or they want to avoid choosing the wrong size. No doubt, knowing the ideal size to purchase is always the smart thing to do but not many people know how to choose the right size.

Trust us, choosing the correct dildo size is not as tricky or complicated as you might have thought. It involves you checking out certain metrics and ensuring that they’re perfect for you before making the purchase. Easy-peasy, right? We thought so too. So let’s get right to it!

How Sex Toys are Measured

Several metrics are used in measuring the size of sex toys. Generally, you need four metrics to get the proper measurement of a sex toy. Below, we’ll tell you all about these metrics:

Overall length

You can’t talk about measuring a sex toy such as a dildo without looking at its overall length, also known as the total length. The overall length is the toy’s vertical length from the two farthest points.

Girth

The girth of a dildo is the circumference of the sex toy at its widest section. Basically, the dildo’s girth is the measurement of its thickness. To determine the dildo girth, you’ll have to measure the thickest part of the sex toy.

Insertable length

The insertable length of a dildo is pretty self-explanatory. This is the measurement of the section of the overall length that can be safely inserted into the orifice, whether vagina or anus. According to the United Kingdom’s (UK) National Health Service (NHS) Trusted Source Penis size Many men worry their penis is too small. Find out what the average penis size is, and how most women are not interested in penis size. www.nhs.uk , it is standard to measure from the base to the tip.

Width

The width of a dildo is pretty much its diameter—the distance between both sides of the sex toy. While the girth is the measurement of the overall thickness of the dildo, the width is the measurement of the distance between the left and right sides.

These four metrics combine to determine the best small dildos and the best large dildos. With them, you can also arrive at an average dildo size for your preferred products.

Comparing Length and Girth

You can put the length of dildos into perspective using a soda bottle which measures 4.8 inches. For example, a 6-inch dildo is only 1.2 inches longer than the soda bottle while a 10.5-inch dildo is longer than two soda bottles stacked on top of each other as the image below shows.

Which is the most popular?

In the United States, more than 3,000 people search 12-inch dildos monthly, making that category the most popular size dildo even though the average length of an erect penis is between 5.1 and 5.5 inches according to researchers. Trusted Source Average-Size Erect Penis: Fiction, Fact, and the Need for Counseling - PubMed Most men believe that the average length of an erect penis is greater than 6 inches (15.24 cm). pubmed.ncbi.nlm.nih.gov

Dildo Sizes by Type

As we hinted at the beginning of this article, dildo types have sizes. Below, we’ll discuss the range of dildo sizes by type:

Inflatable

If you didn’t know, inflatable dildos allow their sizes to be increased to specific levels besides their original sizes. Specifically, the average inflatable dildo can be increased in length, girth, and width. The length that can be inserted often ranges from 5 – 7 inches while the girth typically falls between 5 and 12 inches.

Additionally, it’s usually up to the user to inflate the inflatable dildo to their preferred sizes. The Cock Locker Inflatable Penis paints a good picture of how this type of dildo can be adjusted. This product can be inflated from 5 to 12 inches in girth and 6 to 7 inches in insertable length.

Glass

Glass dildos are made from a pretty solid material, so you’ll do yourself a world of good to choose the correct size only. This type of dildos typically comes in girth sizes ranging from 2/3 inches to 6/7 inches. On the other hand, their length ranges between 5 inches and 9 inches.

For example, the Lovehoney Beaded Sensual Glass Dildo, which can be heated or cooled for added temperature play, has a circumference of 4.25 inches, an insertable length of 7 inches, and an overall length of 9 inches.

Anal

Anal dildos are quite different from vaginal dildos. Although some people use vaginal dildos for anal play, they can’t do the job quite like anal dildos that are specially designed to get the job done. Generally, anal dildos measure between 1 inch and around 9.5 inches in girth. In terms of insertable length, they typically measure between 4 inches and 10 inches.

If you’re looking to purchase the best anal dildo or the best dildo for men you must choose an option that’s ideal for the girth and length of your butthole.

With balls

Truly, most dildos are designed with only the penis in mind, only some models care to be more realistic by incorporating balls, veins, muscles, etc. Dildos with balls come in insertable lengths between 5 inches and 9 inches.

The Si Novelties Extra Thick Suction Cup Dildo is a good example of a dildo with balls. You can tell from its 8-inch insertable length and 8-inch girth that it’s within the range of other dildos with balls in terms of size.

Ejaculating

Since ejaculating dildos are designed to simulate men spurting out their cum, they typically—as expected—feature balls. The presence of balls adds to this dildo type’s overall length but the insertable length range is not very different from other types. The insertable length of ejaculating dildos ranges from around 5 inches to 8 inches while the girth is between 4 and 7 inches.

High-quality ejaculating dildos such as the Doc Johnson Bust It Ejaculating Realistic Dildo do not stray from that range as its insertable length of 7 inches and girth of 5.75 inches show.

With suction cup

You probably know this: suction cup dildos are specifically designed for hands-free sexual play. Therefore, you must know the ideal size you can take before making your choice. Besides, suction cup dildos’ insertable lengths range from 5 to 10 inches. Their girth size, on the hand, is between 3 and 10 inches.

Many top products such as the Lovehoney Curved Silicone Suction Cup Dildo fall in these categories. The dildo, which features a curved, semi-realistic tip to please P-spots and G-spots, measures 4.75 inches in girth, 6.5 inches in insertable length, and 7 inches in overall length.

Curved

Curved dildoscan be very satisfying sex toys to target G-spot but the best way to get excellent results out of them is to choose the right sizes. As the Lovehoney Satisfy Me Curve Silicone Dildo with 4.25 inches’ girth and 6.5 inches suggests, curved dildos’ girth usually falls between 3 inches and 5 inches, and their insertable length is between 5 inches and 9 inches.

Metal

Metal/stainless steel dildos are not very different from regular dildos in terms of size. This type of dildos often comes with an insertable length of 4 – 9 inches and a girth of 4 – 7 inches. A quick look at a metal dildo like the Desire Luxury Beaded Stainless Steel Dildo, which has a girth of 5 inches and an insertable length of 6.5 inches, confirms these size limits.

Electric

Electric dildos can be pretty fun but they’re best enjoyed when the size is right. Their insertable length ranges from 4 inches to 10 inches and their girth is usually between 3 inches and 6 inches as the ElectraStim Bi-Polar Electrosex Wave Metal Dildo with an insertable length of 5.5 inches and girth of 3.5 inches shows.

Realistic


Remember that we said some dildos are designed with features such as balls and veins to look and feel realistic: the Realcock2 Dirk is one of those dildos. Measuring  8-1/2 inches in insertable length, 2 inches in width, and 6 inches in girth, this sex toy falls well within the sizes of realistic dildos.

Realistic dildos often come with an insertable length of 5 inches to 11 inches, a girth of 5 inches to 10 inches, and a width of 1 inch to 4 inches.

Strapless strap-on

Strapless dildos sport a unique design that limits their insertable length to around 7 inches from about 4.5 inches. Their girth, which is a very important consideration, usually ranges from about 3.75 inches to around 5.5 inches. This is evident in the Lifelike Lover Luxe Posable Strapless Strap-On which measures 4.5 inches in girth and 6 inches in insertable length.

Vibrating

Vibrating dildos, also known as thrusting dildos, sport unique designs that extend to their sizes too. The best thrusting dildos can come with a girth of 4 to 7 inches and start with an insertable length of 5 to around 8 inches.

Fantasy

Fantasy dildos have this monstrous feel about them that extends to their sizes too. Therefore, you’ll need to pay great attention to the size of this type of dildo before investing in it. The best fantasy dildos on the market feature a girth between 1 inch and 10 inches as well as an insertable length between 4 inches and 12 inches.

Double

Double dildos typically feature two sections: vaginal and anal section. The vagina section of the best double dildos typically ranges in sizes of 4 inches to around 7 inches in insertable length while the anal section ranges in sizes of 3.75 inches to around 5 inches in insertable length.

In terms of girth, the vaginal shaft measures between 4 inches and approximately 6 inches while the anal portion ranges from 3 inches to approximately 4 inches.

Giant

How big are dildos? Check out the giant dildos which are unsurprisingly large, both in girth and insertable length. The girth of this type of dildos typically runs between 4 and 10 inches while their insertable length can start around 7 inches and go as far as 16 inches. The Lampwick Uncut, which boasts four monster sizes, is a good example of how big giant dildos can get.

How to Measure Yourself for Dildo

It’s not just enough to know dildo dimensions, you must be able to tell which sizes are ideal for you. We know you’ve been gearing to learn how to measure yourself for dildo and we’re going to help you choose the best dildo size:

Anal

You’ll need to be very relaxed to measure yourself for an anal dildo. You’ll also need a lot of lube and your partner to help you out. After lubing up your butthole, your partner should stick in a finger, and after a while, insert a second. They can do more until you’re at your most relaxed place and have realized your limit. Your partner can then bring out their fingers and measure around them with a soft measuring tape to know the girth.

To know the insertable length, you’ll need to insert an item that has a smooth surface and is long. Keep on pushing it in your butthole until you find your limit. Mark the point where you’re with your fingers, remove the item, and measure the distance between the tip and your fingers. The distance is the insertable length for your anal dildo.

Vagina

The measurement for the vagina is not so different from the anus. To measure the girth, you’ll also need to follow the same process as the anal measurement. Let your partner insert their fingers into your vagina until you find a limit you’re comfortable with.

Then, measure around the fingers to find the girth your vagina can take.

Final Thoughts

If you’re going to buy a dildo, it won’t be wise to guess the sizes. Guessing the sizes can lead to a wasted investment or unsatisfactory performance. Interestingly, these negatives can be avoided if you buy a dildo that is compatible with your vaginal and anal measurements. You’ll only be able to identify these measurements if you measure yourself for dildo as we’ve explained in this article.

As you can easily guess, dildo sizes vary, but there’s a range for different types of dildos. To get the best out of your dildo, you should only go for dildos that have the ideal insertable length, girth, width, and overall length for your satisfaction.
