Most Popular dildo size that most women prefer is actually the average penis size – 5.1 to 5.6 inches in length and 4.6 to 4.8 inches in circumference. It’s always a safe bet to start average and then go from there.

If you’re new to the sex toy world, you might be absolutely clueless about choosing the right dildo for you.

They might look a bit intimidating for first-time users, but dildos are great sex toys to have in your collection.

Sometimes you might want a quicky with your bullet vibrator, but for those days when you want to feel the fullness of a penis deep inside you, then a good dildo is a way to go.

Now, if you’ve been watching porn, you might think that you need to get the biggest dildo you can find, but it’s really not the case. 

Before you can choose the right size of a dildo, it’s important that you understand dildo sizing first. 

So, let’s start with that: 

The Basics of Dildo Sizing

So, first of all, there are two things you need to measure when choosing a dildo: 

#1: Length

When it comes to length, there is the length of the dildo itself, and then there is the insertable length, which will be the important measure here. 

So, when you’re looking at the dildo you like, always make sure you get these two measurements right. 

Just because the website states that it’s 10″ doesn’t mean that it’s the size of the insertable length!

Now, if you’re not sure how to judge the length of the dildo just by having the numbers, we have a great image that will allow you to understand sizing a bit better:

Having the dildo compared with the can of soda is the best visual, and you can easily imagine the size. 


#2: Girth

The next measure you’ll need to pay attention to is the girth of the dildo. 

Usually, the girth of the dildo is listed as the width of the shaft (diameter) or circumference around the shaft.

Here is the table that will help you understand the measurements a bit better:

DIAMETER1”1.25”1.5”1.75”2”2.5”3”
CIRCUMFERENCE3” – 3.5”3.75” – 4”4.5” – 4.75”5” – 5.5”5.5” – 6.75”7” – 7.75”8” – 8.5”

When you are choosing the girth of the dildo, you should know that on average, the longer the dildo, the thicker it’s going to be. 

Now, the majority of dildos have a width (diameter) between 1″ and 2,” and the average penis girth is around 1.5″.

Some sex educators believe that girth is the most important part of choosing the correct size of a dildo and not the length. 

You should pay attention to the girth and see which you prefer in real life.

One thing to keep in mind:

If you don’t have the experience with penetration, it might be a good idea to go even smaller. 

I would suggest going for a dildo that has a girth of less than 1″ diameter and then sizes up if you feel like you want a fuller feeling. 

Also, talking about sizing up – go for a 0.25” increments in girth, this way you will ensure you can take the dildo in with comfort.


Dildo Size Chart

Here is an approximate dildo size chart to help you better understand the sizing:

LENGTH6”7”8”9”10”11” – 12”
GIRTH4.5” – 4.75”4.5” – 4.75”5” – 5.5”5.5” – 6.75”7”7” – 7.75”

For the best results, you have to always check the manufacturer’s size chart or the website that you’re buying from. 

While you can expect for the dildo girth to go up in size linearly with the girth of it, it all depends on each seller individually. 

Most of the websites that sell dildos have sizing information with each individual toy, so it shouldn’t be an issue really.


How To Understand The Real Size Of A Dildo?

There are lots of numbers and different measurements to understand here, right?

I know it can get a bit overwhelming if you’re new!

But listen, it’s really not that difficult:

Always try to compare the dildo size with the average size of the penis. If this doesn’t help, then the cola can chart at the beginning of this post should help you understand the size of the toy better. 

And remember, if you’re unsure about the size, always go with the smaller option as you can always go bigger later on!


How To Decide The Best Dildo Size For You?

Now that we discussed the most important measures let’s get into the tips for choosing the right dildo size for you.

#1: Measuring The Length

Most women prefer the average penis size dildo, which is around 5″-6″ in length and 1.5″ girth in diameter.

I recommend starting out on the safe side and going for the average size if you’re not sure what you prefer. 

Once you get comfortable with the average length, you can see what works for you better:

Maybe you’ll want to go smaller and get a dildo that’s G-spot orientated. 

Or maybe you’ll want to go bigger and have that fullness feeling while using it. 


#2: Measuring The Girth

When it comes to measuring the girth when choosing the dildo size, I recommend using your fingers. 

See how many fingers you like to insert inside yourself and what feels the best. 

Then measure the circumference of your fingers and see what girth is that when you buy a dildo. 

This is the easiest method, and you’re in full control of what you choose. 


#3: Watch And Read Reviews Before Buying

You know when you buy a pair of jeans in American Eagle, and they fit perfectly, but when you get a pair from HM in the same size, they run a bit small? 

Well, the same goes with sizing for dildos as well:

Each brand sizing can vary, so you need to keep in mind that the dildo you choose might be bigger or smaller. 

Now, the best way to go about this issue is to watch and read sex toy reviews. 

There are plenty of great sex educators online who do reviews of various sex toys, and you can easily find information on the dildo you’re interested in buying. 

Check their reviews and see what they say about the size and whether it’s true to size or whether you should order bigger/smaller. 

This will save you time and having to deal with returns. 


#4: What Is The Perfect Dildo Size?

Now, you might still be waiting for me to tell you the perfect size for a dildo and make this whole process easier for you. 

But I can’t do that as in reality, the perfect dildo size is the one that you enjoy the most.


Other People Tips & Experiences

Now, let’s take a look at what other people on the internet have to say about choosing the right dildo size:

I always get the size that is too big, sometimes way too big. Then I get a size that is smaller but still a bit too large. I then use that smaller one until I can use it without pain, then I go for the one that is way too big.

It’s always a mix of pleasure and pain but I always get to the largest one, it’s a stretching challenge. Now I start with a very large one because the head is smaller and quickly widens to a 3.5″ dia. shaft.

My smaller ones don’t get much use anymore. Point is, go for the one that turns you on even if it’s too big but has a backup that will help you get there

Another thing to keep in mind is that being penetrated by a dildo feels pretty different from being penetrated by anything actually fleshy – be it fingers, tongue, or penis.

A person might be totally into being penetrated by a big dildo but might enjoy a smaller or average-sized penis more, or vice versa. Some might like being penetrated by a penis, but hate the feeling of being penetrated by a dildo.

Another factor is the material of the dildo. Something that feels more like flesh might be a more accurate guide to preferred penis size, while harder materials like glass might give a very different idea.

I don’t have stats, but keep in mind that if you’re looking at the overall length then you’re likely to be getting a pretty serious overestimate. Dildos need an end to hold onto to be used effectively; penises come with a human body instead.

That’s even assuming that your initial premise is correct—that women want the same penetration experience from dildos that they want from penises, and that dildo purchases are representative of the population of women you’re interested in.

Initially, your approach seems like a good idea but I’d bet that you wind up with more confounding variables than it’s worth your time to deal with.

Frequently Asked Questions Answered:

And now, I have answers for you to the most popular questions about dildo sizes:

1. What Is The Best Selling Dildo Size?

According to research, the most popular dildo size is 7.52″ in length and 5.16″ around the shaft. It’s 21% longer in length than the average penis and just a bit thicker.

2. What Size Dildo Do Woman Prefer?

There is no one answer to this question. While the best selling dildo size might suggest that that size is the one that women prefer, it’s not really that simple.

It really depends on women and what do they prefer. Some like to use dildos that are very large, some like it small, and some like it average.

The preference also is different depending on the purpose of the dildo. If a woman is using it for vaginal masturbation, she might prefer a larger dildo than for anal masturbation.

So, there is really no one-size-fits-all answer to this question. 

3. What Is The Biggest Size In Dildo?

There are dildos that go up to 20″ and more in length. They’re definitely for experienced users only…

But if you’re curious to know what is the size of the biggest fake dick in the world, it would be 12-foot and 4″ long. You can find an article and pictures of it here.

Really quite an impressive piece of art if you ask me!


Conclusion

And here you have it – everything you need to know about choosing the right dildo size. 

Buying the right one might take some time and trial and error along the way. 

I recommend starting with the safe option and buying an average size dildo first. You can always adjust and go bigger or smaller once you know where your comfort zone is. 

And don’t be ashamed of your personal taste in dildos is different from an average person; everyone has different tastes!
