Vibrator Sizing Guide - How To Choose The Perfect Size for Any Vibrator Type

How do you measure sex toys?

Generally speaking, there are four measurements you should be familiar with.

Length: The vertical length of the toy from the two farthest points. We sometimes refer to this as total length as well.

Length: The length of the toy designed to be safely inserted.

Width (or diameter): The distance between the two sides of the toy.

Girth (or circumference): The circumference of the toy which is relevant toys.

How do you measure yourself for vibrators?

To size yourself, you need a tape measure and your fingers to measure the width/girth.

Insert your fingers into the vagina to what is comfortable for you; use lubrication as necessary. Once you have this, measure across your fingers to give you the width/diameter, or you can wrap a soft tape around your fingers to find the circumference/girth.

Girth/circumference size ranges from around 1.5 inches (average male penis) all the way to 2.5 inches for larger vibrators.

Vibes come in all manner of lengths and are often about the girth. Lengths available are from around 2.5 inches all the way up to 12 inches.

Choosing vibrator length is subjective because you can adjust how far you insert it. The female G-spot is only 2 to 3 inches inside the vagina, so longer is not always better.

Sizing for bullet vibrators

Bullets are one of the easiest sex toys you can measure yourself for because they are designed with discretion in mind. In most cases, the maximum length they come in is around 5 inches in length (insertable).

Bullets are designed to be smaller, but they do come with variable girths. These range from just under 2 inches to up to 5 inches in circumference. It is vital not to confuse diameter with circumference because they give very different sizes.

Sizing for clitoral stimulators

Clit vibes are another vibrator type which doesn’t penetrate the vagina and focuses on external stimulation. Measuring for these doesn’t require length or girth/diameter to be measured.

They do come in a few variations, so knowing if these will fit around the clitoris will determine whether or not you get the best experience. The primary type of clit vibes do come with a device that is held in the hand with a small ring that sits over the clitoris. These are generally one size, but the handle size can vary.

To measure what you can easily hold, you can find something that you can comfortably wrap your fingers around and that is comfortable to hold in the vaginal area. From this, you can determine the ideal length of the device. Clitoral vibes of this design can range from 2 or 3 inches in length, right up to around 5 or 6 inches.

Sizing for double finger vibrators

Finger vibes come in a couple of varieties depending on their use. This can mean there are a couple of ways to measure yourself to find the best size for the job.

Finger vibes (which are only meant for erogenous zone stimulation) sit on the fingertips, so there is no penetration. The sizes of these are around 2 inches in length and have a 1 inch diameter. This delivers around a 3 inch girth.

Measuring the finger you will be wearing the finger vibe on isn’t necessary in most cases, and this is because the finger straps are stretchy and fit almost all finger sizes. Depending on the wearer, this can mean they might need to change finger if their middle one is either too large or too small.

Insertable finger vibes can also come with a ‘one size fits all’ finger ring, but the penetrating portion will vary in length and width. These are generally only around 1 inch length and width, that’s unless you choose the variety that’s a vibrating sleeve and sits covering the finger. If choosing this type, it’s a matter of measuring the finger length with a tape or ruler to make sure the finger vibrator will fit. These can range from 3 inches in length to around 6 inches.

Sizing for g-spot vibrators

Finding the right size of g-spot vibe doesn’t focus on length because the g-spot sits a couple of inches inside the vagina. This can make the size measuring a little more straightforward. However, there are larger g-spot vibrators, but these more extended versions will not be of use for g-spot stimulation.

Most common g-spot vibes come with a length of around 5 to 6 inches, but the section that can be inserted ranges from 4 to 6 inches for smaller models.

Large models can reach lengths of 9.5 inches, and with an insertable length which is around 7 inches, girth/circumference of this size is usually in the range of 4.5 inches to 6 inches.

Sizing for rabbit vibrators

Rabbit vibes are unique in how you can measure for their use. There will be a significant portion that isn’t inserted and acts as a handle. Just finding the insertable length you can accommodate will leave you unsatisfied, as this won’t relate to the size of the rabbit vibe overall.

When you look at rabbits, the insertable length is from the base of the rabbit ear attachment. This will be the length you can accommodate, but the length of the rabbit vibe might be almost double in length. To put this in perspective, you can purchase a rabbit vibrator which is almost 10 inches in length, but the part you insert into the vagina is only between 5 to 6 inches, so bear that in mind.

Small rabbits come in a range between 3 inches and up to around 6 inches in insertable length. Larger rabbit vibrators can range from 6 inches to approximately 1o inches (and above) in length.

Thinner rabbit vibes will come in a range up to approximately 5 inches in girth, while the larger variety can fall into the 7 to 9 inch range for circumference.

Sizing for rechargeable vibrators

Sizing yourself for a rechargeable vibrator is no different than a regular vibrator.

Rechargeable vibes can come in lengths from as small as 3 to 4 inches and go all the way to large sizes of approximately 12 inches and above.

Small rechargeable vibes have girths/circumferences which range from 3 inches to 5 inches. Anything above 5 inches in girth falls into the large category.

Sizing for tongue vibrators

These vibrators come in a couple of varieties, so measuring for these is very different. You can have the type which simulates a tongue, or the kind which sits inside your partner's mouth.

Tongue vibes which are for oral play are shaped like a tongue and in most cases are not used for penetration. However, some are intended to penetrate a couple of inches. To size yourself for this type, you can insert the tips of two or three fingers into your vagina, and then take a tape measure and measure across the width. This gives you the diameter. In most cases, this type of tongue vibe will go on diameter more than girth.

The overall length ranges from around 6 to 7 inches but only have approximately 2 to 3 inches that can be inserted.

The type which sits on the tongue or inside the mouth is slightly different. These are the size of a mouth guard. These come in one size and are flexible. Mouth guard sizes are around 2.5 inches in length and 1.75 inches in width, approximately.

Sizing for vibrating panties

Vibrating panties come in a couple of varieties. The more common being ones that have a small vibrating unit that sits close to the clitoris for external stimulation. This type is the easiest to size yourself for, mostly because you only need to know your waist size.

Many panties of this nature are adjustable but come in the ranges of US sizes (between size 4 and size 12).

Other vibrating panties come with a short, insertable dildo. Insertable length doesn’t need measuring, and all you need to find is the circumference of the vagina for the most comfortable fit.

Remove your fingers and measure around them with the tape to get the circumference reading. This will be the size of panties (with dildo attachment) that you can comfortably wear.

These come with (small nub) vibrating dildos that are around 3.5 inches in length and range from approximately 2 inches to 4 inches in circumference.

Sizing for wand vibrators

Wand vibrators are not designed for penetration, so this makes sizing for these very easy and can be done by yourself in a couple of minutes.

These wands are designed for clitoral and external stimulation. They do come with different sized heads, so knowing which size is suitable can make the experience more pleasurable.

The best way to choose the right head size is by measuring the distance between the top of your thighs across the top of the vulva (the outer part of the vagina). This will give you a minimum distance when your legs are shut.

If you part your legs, you can measure between your thighs. This is the size you would need for a maximum head for a wand vibrator.

Manufacturers typically measure the head of the wand vibrators in circumference, but you will have the width or diameter. Take the measurements you have and multiply by 3.14 (pi), and this will give you the circumference. Now you can see what sized (wand vibrating) head will fit comfortably on your clitoris, or further between your legs for alternative stimulation.

Wand massagers come with a head circumference from as small as 2 inches for the mini variety and can range up to 7.5 inches for larger versions.
