Whether you’re a beginner or an advanced user, choosing the right size butt plug (also called a butt plug) can be difficult.
First and foremost you want to make sure you’re comfortable, but you also want good stimulation – after all, that’s what it’s all about!

Butt Plug Anatomy

While there are countless exciting design features, all butt plugs have a few things in common. The one with any toy you want to use anally has a wide base to prevent it from going all the way inside you, migrating up and requiring a trip to the emergency room to get it out.
Then there is a neck around which the sphincters contract to hold the plug in place. In addition, butt plugs have a conical tip that makes insertion easier.
The two measurements to consider when buying a butt plug are the insertion length, i.e. how far it fits into you, and the diameter. Some sites give diameter and others give circumference – so pay attention to which measurement is given!
We’re going to talk about diameter today because it’s easier to visualize, but if you want to calculate circumference, you can do it here:
Circumference = diameter x π, so 3.14
Butt plug size chart




This chart is an estimate of the different butt plug sizes, but just like dress sizes, not all stores will categorize small, medium, and large in the same way. This means that it is super important to always check measurements.
There are no hard and fast rules when it comes to choosing butt plugs as everyone’s butt is unique. In addition to physiology, your well-being also plays a role in choosing the right size. If you’re nervous, you’re likely to tighten your muscles more, so it’s better to choose a smaller size. When it comes to anal play, it’s always best to go slow and gentle. Start with a smaller plug, get used to it, enjoy it, and then move up to a bigger size if you want!
Beginner – XS
If you’re brand new to anal penetration, have a very small body, or are afraid of sticking something up your butt, you should start with an extra small plug.
As a rule, the plugs have a diameter of less than < 2.5 cm and are therefore very slim. Depending on your body, you may not feel much stimulation to find out if you like anal play and get used to the feeling.
Beginner – p
Small plugs usually have a diameter of between 2.6 and 3 cm and are also suitable for beginners. If you’re not nervous about trying a butt plug or have had some experience with anal play, such as with a finger, then you might want to try a small plug for a little more stimulation.
Intermediate – M
Medium-sized butt plugs are between 3.1 and 4 cm in size. The average size of an erect penis is 4 cm. Also, so if you’ve had anal sex before or used a finger or two, go for this size.
Advanced – L
For people who already have experience with medium sized plugs or who are familiar with anal sex with a penis or dildo can opt for this size. Large butt plugs are typically between 1.6 and 2 inches in diameter and offer a satisfying full stretch.
Expert – XL Buttplug
From here we have reached sizes of staggering proportions! Typically over 5cm in diameter, the plugs offer an intense feeling of stretch and are best for anal lovers who want to experience extra large and intense sensations. In preparation for butt plugs of this size, you should gradually build up your tolerance with smaller plugs before attempting to insert an extra large butt plug.
How to go up a size with butt plugs…
The most important thing is to go slow and steady! I know the big plugs look tempting and you’re thinking how wonderfully full they’re going to feel, but trust me you don’t want to rush it. Even if your brain thinks you’re ready, it takes time for your butt to get used to it. Give yourself enough time to enjoy each phase.

What size is safe to wear all day?
Sure, wearing a butt plug is a great way to spice up the chores a bit. However, it is recommended not to wear a butt plug for more than 2-3 hours at a time to limit the possibility of damaging tissue by restricting blood flow. Are there people who wear them longer? Yes. Is that recommended? No! You can still have the pleasure of wearing a plug in public or during everyday activities, but don’t forget to give your butt a rest and always check for signs of irritation or damage. And of course, if you notice any pain or bleeding, take your butt plug out immediately.
If you want to wear your butt plug for a few hours at a time, you should pay attention to a few features:
- Soft silicone is the best material as it is much more comfortable, especially when you are sitting down.
- Choose a thin, flexible neck so your sphincters don’t get stretched too much.
- A T-bar base is most comfortable because the base can sit comfortably between the buttocks.
Tips for using butt plugs
Now you know exactly what size to buy. Here are some tips for a smooth ride on your first trip with butt plugs!
- Always start small – both in the long run and at every session! Start by massaging the anus, then use smaller toys or a finger to warm up before using something larger.
- Unlike the vagina, the anus doesn’t produce its own lube, so lube is very important! Just make sure the lube you choose is compatible with the butt plug you choose. Water-based lube works best on silicone sex toys but requires more frequent application, while silicone lube works better on metal or glass butt plugs and glides better.
- If this is your first time using a butt plug or anal toy, you might want to try it in the shower first. The warm environment can help you relax, which makes insertion much easier.
- Practice safe sex. If you share your sex toy with a partner who you are not committed to, cover the toy with a condom.
- Make sure you clean your butt plug thoroughly after use.
- Always listen to your body! If you experience pain or bleeding while inserting or while wearing a butt plug, stop immediately! Then remove the butt plug and assess the situation.
