Introduction
When it comes to buying a dildo, one of the most common questions people ask is: what size should I choose? Dildos come in countless lengths, girths, and designs, which makes the decision feel overwhelming—especially for beginners. Understanding the most bought dildo size can help guide your choice, but the truth is that the perfect fit depends on your comfort level, body, and experience.
At RealCockToys, we believe that knowledge and safety are the foundation of good sexual exploration. In this article, we’ll explore which dildo sizes are most popular, why size matters, and how to find the right toy for your unique preferences.

The Importance of Size in Dildo Shopping
Size isn’t everything, but it certainly matters when it comes to pleasure and comfort. A dildo that is too large can cause discomfort or even injury for beginners, while one that is too small may not provide enough stimulation for experienced users. The most bought dildo sizes reflect the balance people look for: realistic sensations without overwhelming the body. Most shoppers gravitate toward average-sized dildos that mimic the size of a natural erection, which tends to be around 5 to 6 inches in length and 1.25 to 1.5 inches in diameter. These dimensions provide a realistic experience while being comfortable for a wide range of users.
Why Average-Sized Dildos Are Popular
Average sizes are the most purchased because they are versatile. They are easy to use for vaginal penetration, accessible for anal beginners, and ideal for those who want something that feels realistic without being intimidating. Larger dildos are often reserved for advanced users who enjoy stretching sensations, while smaller toys are typically bought by beginners who want to ease into penetration gradually. The average size hits the sweet spot of realism, pleasure, and comfort, making it the most commonly bought dildo size worldwide.
Different Size Categories Explained
Although the average size is the most popular, it helps to understand the full spectrum of dildo sizes available. Small dildos, usually under 5 inches in length with a slim girth, are recommended for virgins or absolute beginners. Medium dildos, ranging from 5 to 7 inches, are the most widely purchased because they provide a lifelike feel without overwhelming the body. Large dildos, over 7 inches, cater to advanced users looking for intense penetration. There are also extra-large or “monster” dildos for size enthusiasts, though these are considered niche purchases.
How to Choose the Right Size for You
Choosing the right size is less about following trends and more about listening to your body. Beginners should always start small, focusing on slim dildos with smooth surfaces for easier insertion. Once you are comfortable, you can gradually explore larger lengths and girths. Consider your intended use as well—anal play requires toys with a flared base for safety, and smaller sizes are often better to start with. Vaginal play allows more flexibility in size, but comfort should always come first.
The Role of Girth and Length
When talking about size, people often focus on length, but girth plays an equally important role. A dildo with moderate length but thick girth can feel fuller and more intense than a longer toy that is slim. Beginners usually find slim girths easier to handle, while advanced users often seek toys with greater thickness for increased stimulation. Ideally, the best toy for you balances both length and girth in a way that feels satisfying without causing discomfort.
Material and Size Experience
The material of a dildo can also affect how size feels. Silicone is flexible and forgiving, making larger toys easier to handle. Glass and stainless steel dildos are firm, which means that even smaller sizes can feel more intense. Soft, squishy toys with dual-density construction can provide a lifelike feel even when the toy is on the larger side. At RealCockToys, we stock a wide range of body-safe silicone dildos that combine realism, comfort, and durability.
Why People Experiment with Different Sizes
Many people start with an average dildo size and then branch out into larger or smaller toys to explore new sensations. Some enjoy switching between sizes depending on their mood, while others may use smaller toys for warm-up before moving to larger dildos. Variety is part of the fun of sex toys, and experimenting with different sizes can help you discover what truly satisfies you.
Tips for Buying Your First Dildo
If you are a beginner, focus on comfort and safety. Choose a smaller dildo, around 4 to 5 inches, with a smooth surface and a flared base if you intend to use it anally. Always use plenty of water-based lubricant to reduce friction and make penetration easier. Take your time and listen to your body—pleasure should never come with pain. Once you become comfortable, you can explore medium sizes, which tend to be the most commonly bought and loved.
Advanced Users and Size Play
For advanced users, larger dildos offer unique sensations. Deep penetration, stretching, and fullness are common reasons people enjoy big toys. However, safety remains critical. Larger toys require more lube, slower insertion, and plenty of relaxation to prevent discomfort or injury. Some advanced users enjoy size play as part of their sexual identity, seeking out toys that push the boundaries of what they can handle.
Why Most People Stick to Average Sizes
Despite the fascination with large or extreme toys, sales data consistently shows that average dildo sizes dominate the market. This trend reflects the balance between safety, realism, and pleasure. Average sizes provide enough stimulation for satisfying orgasms without being intimidating. They are also versatile enough to work for both solo sessions and partner play, which makes them appealing to the widest group of buyers.
Final Thoughts
So, what is the most bought dildo size? The answer is clear: average-sized dildos, usually around 5 to 6 inches in length and 1.25 to 1.5 inches in girth, remain the top choice for most users. These sizes are realistic, versatile, and satisfying without being overwhelming. While size preferences vary widely depending on experience, comfort level, and personal desires, the trend toward average dimensions shows that balance is what most people seek.
