Anal Toy Sizing Guide - Sizing Info You Need From Butt Plugs to Prostate Massagers

by Kate Miller on Jan 07 2026

When it comes to trying anal toys, you need to use the appropriately sized toy to get the best, most comfortable experience. The perfect anal toy will provide a pleasant sensation of stretching your anus without being too overwhelming or painful. So, today we’ll share our guide on how to measure your body (or your partner’s body) for anal toys; you’ll learn the essential metrics about anal toys and how to find the best one for you.

What Are Anal Sex Toys?

Anal sex toys are a group of adult toys designed to be used for anal play. These include butt plugs, anal beads, prostate massagers, anal dildos, and other exciting toys that you can use in your backdoor. Each of these comes in simple and sophisticated variants, with models having very advanced features that provide highly satisfying sensations.

What Size Anal Toy to Get: Measure Your Anus

The short answer if you don't want to measure anything is to get a small, beginner size anal toy, so you won’t risk overstretching your anus to the point of pain or even tearing of the soft tissues. To find the exact measurement of the anal toy, you should start, you can use a simple measuring technique to measure the anus. You can do this by yourself or with the help of a partner; in any case, you will need some lube and a tape measure.

Start by relaxing your body and getting comfortable; position your body as you like it; it can be on your back, on all fours, or your side. Add a fair amount of lube to your anus and your fingers, and start inserting one into the anus. For more comfort, push out as you or your partner slips a finger inside. If you are comfortable with one finger and feel like you can take more, then you can add in another one, and once you reach your limit, mark the point of how far the fingers are inserted into the anus. Remove them and measure the circumference by wrapping the tape measure around the widest part. It will give you the maximum circumference your anus can stretch at the moment, so you need to look for an anal toy that is this size.

However, you will note that plenty of our product descriptions share the diameter instead of the circumference of the anal toy. So, to calculate the diameter you can comfortably manage, you need to divide the measured circumference by 3.14. Once you know the diameter, you can look for an anal toy that is closest to your measured dimensions.

When it comes to the length of the anal toy you can safely take, you can measure this, or you can get an anal training kit that comes with anal trainers in varying sizes. These are designed to help anyone train their anus to take up toys and get used to the stretching sensation.

Different sizes of anal toys

Anal Toy Models

There are plenty of different and exciting anal toys for you to try, which is why we made a list of the models you can find in our sex toy store. We also have separate guides on choosing and using different sex toys, which you can check out on our blog, which we urge you to check out.

Butt Plugs

The seemingly simple butt plug is a perfect anal toy, as it has an optimized shape and comes in so many sizes that fit users of all experience levels and needs. When you measure for a butt plug, make sure you measure the diameter as we explained above, and always err on the smaller side, meaning choose a somewhat smaller size plug as these may feel overwhelming if you are not used to them.

Here is what you need to know regarding the anatomy of a plug to select one you'll enjoy:

  • Butt plug tip – the tip of the butt plug is the first to go in, so its shape has an important role. The butt plug tip can be pointed, curved, rounded, or ridged. The pointed tip makes insertion easier; the rounded tip provides an initial stretch and allows smoother entry; a curved tip is perfect for prostate stimulation, while a ridged tip provides extra sensory stimulation.
  • Butt plug body – the body of the butt plug is the section that provides the most stimulation, and here you need to know its insertable length and insertable diameter.
    • The insertable length is the length from the tip of the butt plug to the neck or the part that goes inside your body. It can be small, with a length of 2 to 3 inches; medium, with a length of 3 to 4 inches; large, with a length of 4 to 6 inches; and anything over 6 inches is considered an extra-large length.
    • You also need to know the insertable diameter or the diameter of the butt plug at its widest point. It is a more important metric for satisfactory use. The diameter is the length across the plug, while the circumference is the length around the plug, as different product descriptions may include these two metrics. We prefer using the diameter metric, and based on this, there are extra small butt plugs with a diameter of less than one inch, which are the best beginner-friendly models. The small butt plugs have a diameter of 1 to 1.25 inches, medium butt plugs have a diameter between 1.25 to 1.5 inches, large butt plugs have a diameter of 1.5 to 2 inches, and anything with a diameter of over 2 inches is considered extra large.
  • Butt plug neck – the neck connects the body of the butt plug to the base, and this part sits on the anal sphincter. It keeps the anus stretched, and depending on the design of the butt plug, this size can be long or short and can be narrow or thicker. There is no right or wrong design, as it comes down to personal preference. However, we must note that a butt plug with a longer neck can be more easily positioned and removed.
  • Butt plug base – the base is part of the butt plug that sits outside the anus, and it has a flared shape to prevent the plug from traveling inside, as it has to have a significantly wider size than the body of the plug. The base can be circular, square, heart-shaped, elongated, or T-shaped. While it serves to prevent the plug from getting stuck inside the anus, you can use the base as a handle to insert or remove the plug easily.

Please check out our butt plug sizing guide and also our guide on how to choose a butt plug, where we outline all the particulars about butt plugs. Please note that we favor butt plugs made from body-safe materials like glass butt plugs, silicone butt plugs, and butt plugs made from stainless steel.

Butt plug material – the material the butt plug is made from also has an important role, as glass butt plugs tend to feel more intrusive, while silicone butt plugs are softer and more pliable. We don’t recommend you buy butt plugs made from porous materials, but if you do this, use it with a condom to protect your health.

Extra features – there are various butt plugs today, some with a simple design and some with advanced features. There are jeweled butt plugs that add sparkle to your booty play, weighted butt plugs, tail butt plugs that are perfect for people with animal fetishes, inflatable butt plugs, and there are vibrating butt plugs that, on top of stretching your anus, provide satisfying vibrations.

Anal Trainers

Anal trainers are anal sex toy kits that have toys in increasing sizes that are intended for anal training. These usually come in graduated sizes - a small, medium, and large model that you can use to get into the world of anal pleasure. No need to measure here also, as the anal trainer kits come in several sizes that work great for people with little on no experience in anal play. Please check out our guide on how to use anal trainers for more detailed information.

Inflatable Butt Plugs

We list the inflatable butt plugs as a separate entity because these anal toys are designed to provide a highly intense sensation as they stretch the anus. Please note the size of the inflatable butt plug before it is inflated, as this is the size you'll be inserting, and the size of max inflation, and remember that these are not for beginners. These do this by inflating to a much larger size than they initially start with, thanks to a unique inflation mechanism that you can control via a simple squeeze bulb. Of course, there are also automatic inflatable butt plugs, and we invite you to check out our guides on how to choose an inflatable butt plug and how to use an inflatable butt plug, where you’ll learn so much more about this exciting sex toy

Anal Beads

The anal beads are specially designed anal toys that use beads strung together that you use to stimulate the anus and enhance the sensations, mainly when you extract them mid-orgasm. Many people also find the rhythmic stretching and relaxing of the anus intense and pleasurable. You don't need any special measurements for anal beads, as you only need to consider the diameter of the beads - a great thing is that you don't need to insert the entire bead string inside, as you can go at your own pace and add as few or as many beads as you are comfortable with. We prepared complete guides on how to choose anal beads and how to use anal beads that we believe will come in handy for anal beads beginners.

Prostate Massagers

The prostate massagers are anal sex toys designed for prostate owners. The prostate or P-spot is a point that, when properly stimulated, provides intense sensations and is a highly pleasurable, sexy activity. Use the same measuring technique we explained above; you can also engage in prostate massage where your partner uses their fingers to touch the prostate and you can measure that length to find out what size prostate massager to get. There are multiple prostate massager models, and we have complete guides on how to use a prostate massager and how to choose a prostate massager.

Anal Douches

The anal douche is a specialized bulb that allows you to rinse the rectum, which can help you put your mind at ease when you wish to engage in anal sex. The way this work is by squirting warm water into your rectum and expelling it, rinsing fecal remnants and leaving you feeling cleaner, and making you feel more comfortable during any anal play. You don't need to measure anything here also, as only the tip of the bulb goes into your anus; but you do need to consider the design and choose what works best for you. Please check out our guides on how to choose anal douche and how to do an anal douche.
