Vibrator Sizing Guide: Decide Which Vibrator Size to Buy!

What is a Vibrator?

The vibrator is a sex toy that has an internal vibrating mechanism that vibrates and stimulates the areas it is pressed against. The vibrator is one of the most popular and best-known sex toys, with almost 80% of women in the USA having reported they own at least one vibrator. You get a massive selection of different vibrators, ranging from simple dildo-shaped vibrators to bullet vibes, panty vibes, finger vibes, G-spot vibes, and much more. To choose a model that works best for you, you need to first consider if you want to get an insertable toy or one for external stimulation.

Sizing for Insertable Vibrators

We’ll start with a sizing guide for insertable vibrators, as these are intended for internal stimulation, so size is critical here. The metrics you need to know are the length and the diameter of the insertable vibrator. You will also need to consider if you’ll only use your vibrator for vaginal play or if you’ll want to include some anal playtime. If you decide on a vibrator for just vaginal use, then you can go for a model that is longer and girthier, which can provide you with a more delicious stretch.

How to Measure for Insertable Vibrators?

Now, here is how to measure your body so you can get a well-fitting vibrator. We advise you to use your fingers and a tape measure to get precise measurements. First, relax and enjoy some foreplay, and once you feel you are ready, you can insert your fingers into your vagina. Start with one finger and add one (or two) more until you are comfortable with the fit. Measure the diameter across your fingers, and you’ll find the girth you can comfortably manage. Divide this measurement by 3.14, and you’ll get the diameter.

To measure the length, you can use your fingers or another phallic object, like your partner’s penis or a dildo you enjoy using. Insert the dildo/phallic object/fingers into your vagina and measure the length you can comfortably take. Please note that if you want to use the vibrator for G-spot stimulation, you don’t need an extra long toy, as the G-spot is located about 2 to 3 inches inside the vagina, on the front wall. However, if you want to experience deep vaginal stimulation, then you can get a longer insertable G-spot vibrator.

If you are after a combined stimulation, then we recommend you get a rabbit vibe that is optimized for simultaneous clitoral and G-spot stimulation. Measuring for a G-spot vibe is simple because, as we noted, the G-spot is located at 2 to 2 inches inside the vagina, so you should look for a rabbit vibe with about 5 inches of insertable length on average. In contrast, the rest of the rabbit vibe’s length is the handle. However, there are various models that you can find, some with 3 inches in insertable length and others with more than 6 inches in insertable length.

Sizing for External Stimulation Vibrators

Now, we’ll talk about the external stimulation vibrators and how to measure for size. When it comes to external stimulation, you can get finger vibrators, bullet vibrators, panty vibes, tongue vibes, grinding toys, and vibrating wands, to name a few. To pick the model that you will enjoy best, consider the answers to the following questions:

• Broad or focused stimulation – think about the stimulation you want to experience, like a toy covering the entire vulva or a toy that provides a focused, pinpoint stimulation.
• Only clitoral stimulation or whole-body teasing – are you looking for a toy to only stimulate the clitoris, or do you want to use your vibrating toy to tease other erogenous zones like the nipples, the neck, or anywhere else?
• Lightweight and compact or large model– consider if you want to get a small, portable vibe that can be easier to maneuver but comes with less power. Or maybe you want a highly powerful vibrating wand, which comes with the trade-off of being large and bulky and not very portable.

Now that you have the answers, you can narrow down your selection and easily find the external stimulation vibe for you.

How to Measure for External Stimulation Vibrators?

Measuring for an external stimulation vibrator is much easier than measuring for an insertable vibe, i.e., it is not necessary to actually measure anything. Simply consider the intended use and choose a model that appeals to you. The average size of a bullet vibrator is about 5 inches in total, so you can use these to stimulate the clitoris or your other erogenous zones. However, you can also find small bullet vibes that are only 2 inches in length, which are perfect for adding extra stimulation when you play with another toy.

If you’ve opted for a finger vibe, then an important measurement is the loop that attaches the vibe to your finger. However, you can also get models that fit between your fingers, and these come with a "one-size-fits-most" at about 2 to 3 inches in length, allowing you to enhance playtime.

Now, while there is no need to measure for a vibrating wand toy, you need to know that the size of a wand is between 7 and 12 inches, and these are designed only for external stimulation. Because of their larger vibrating heads, these provide more powerful vibrations that spread over a broader area, and you can use these to stimulate the entire vulva or even massage that crick in your neck.
