What’s the Difference Between Length, Girth, and Width?

While shopping, it's best to understand the difference between length, girth, and width. Here’s a bit about each and what they represent.


The length is how long the dildo is. It’s important to note that dildos may be longer than their actual insertable length.

For example, a dildo may be 8.5 inches long, but the insertable length may only be 7.5 inches.

Since the toy might have additional features that limited the extent it can be inserted, it's best to identify the insertable length.

By keeping this in mind, you'll avoid any shopping mishaps that may result in buyer's remorse.


The girth of the toy the distance around the toy. Synonymous with thickness, girth is a crucial factor to the size of a dildo.

For those who are less experienced in the realm of toys (or sex), working your way up in girth can avoid pain. When easing into larger toys, you should also lube up, have some fun, and relax.


Width refers to how wide the toy is. It’s the measurement of the toy from side to side, aka the diameter.

This measurement is often mistaken for girth, but it’s entirely different and may be confusing. Keep in mind: girth is the circumference, and width is the diameter.

Are you looking for that 'pop can' girth?

Aspects to Consider When Buying a New Dildo

Before you buy a new dildo, you should consider the following for each toy on your wish list.


The material of the dildo is critical. Materials include jelly, metal, realistic style, hard plastic, glass, silicone, and more. It's best to pick a material that works well for you and your body.

If you want a more realistic experience, for example, you may consider buying a dildo that features PVC construction and balls.

The material is also an important aspect to keep in mind if you have sensitive skin. If this applies to you, you may want to avoid porous material or latex.


We all know, size matters. Beginners should always work their way up to larger toys and start small. If you don't ease into things, you may end up in pain and turned off. As always, when training up in sizes, be sure to apply plenty of lube and go slow.

Type of Play

Some dildos are for partner play while others are great for masturbating. With this in mind, keep an eye out for the features of a dildo as some are intended for specific positions or add-ons. 

Additionally, you might find yourself eyeing a toy with a suction cup which is always great for some hands free fun.


Some dildos double as a vibrator and add extra stimulation. This two-in-one benefit is excellent for experimenting or having some fun with a friend.

Who Are Thick Dildos Best For?

It’s important to note that thick dildos aren’t for everyone. These above-average toys may cause pain for inexperienced users.

We do not recommend using a thick dildo as your first toy - unless you're experienced with a real big cock.

If you have experience with dildos and want to work your way up, by all means, do. But, when you're just starting out, take things slow.
