Dildo Size Guide - Tips on Picking the Best Size

If you’re going to buy a dildo, it's not recommended to rely on guesswork for determining the sizes. One common error people make when purchasing dildos online is selecting an incorrect size. Dildos range from petite probes suitable for a first-timer to colossal 12-inch models. With countless options on hand, it is essential to know how to pick the best length and width to match your wishes and requirements. If you're contemplating this issue, then this guide is suitable for you. Making an informed decision that works best for your body may be daunting, but rest assured that Funzze is here to assist in selecting a suitable dildo.

Let's begin!

Why Does Size Matter?

Choosing the right dildo size is absolutely crucial, as it will impact the enjoyment you derive from the newly purchased product. Sexual toys come in various sizes, which is a pivotal factor to consider.

When selecting a dildo size, you should take into account the length and thickness of the dildo. Let's delve into the meanings of these terms.


The Two Key Factors

The journey to finding your ideal dildo size begins with understanding two key factors: length and thickness. Each of these factors plays a significant role in shaping your sensations and overall enjoyment.

Length: The length of a dildo directly affects how deeply it can penetrate, catering to both surface and deeper stimulation. Longer dildos offer the potential for deeper exploration, while shorter ones can be ideal for those who prefer more precise targeting.

Thickness: Basically, the dildo's girth is the measurement of its thickness. Girth, or the circumference of the dildo, influences the feeling of fullness and stretch. Some may find more girth satisfying, while others may prefer a more slender option. It's all about personal preference and what feels best for you.

Pro Tip: Keep in mind that softer materials might feel larger due to their flexibility, while firmer materials might feel more precise.


How To Measure A Dildo

Now that we've delved into the factors that influence your choice, you might be wondering how to measure and select your perfect fit. When selecting a dildo, it is usually necessary to consider 4 metrics to get the proper measurement of it:

  1. Total Length
  2. Insertable Length
  3. Width (or diameter)
  4. Girth (or circumference)

These are 4 unique measurements. Typically, longer dildos tend to have greater width and girth, but this is not always the case. Short, thick dildos and very long, skinny dildos can also exist.

1. Total Length

The total length is the dildo’s full vertical measurement from top end to bottom end, including any attached features like balls or suction cups.

If you're uncertain about assessing the length of the dildo solely based on numbers, we provide an excellent image that offers a clearer understanding of sizing.

2. Insertable Length

This is the dimension of potential insertion into the body for a given dildo; however, the presence of balls or suction cups can reduce the insertable length of a 9" dildo to 6" or 5". The length of a dildo can greatly influence your experience. If you're new to using dildos or prefer shallow penetration, opting for a shorter length might be ideal. On the other hand, if you're seeking deeper stimulation, a longer dildo could be more suitable.

Pro Tip: Always consider the 'insertable length' as the portion that will be inserted into your vaginal or anal.

3. Width

The width (or diameter) is the distance between the two sides of the dildo, which plays a significant role in the sensations you'll experience. Consider a dildo like a circle. This value represents the diameter or length of a line drawn through the center of the circle. Even though not all dildos are perfectly circular, this measurement is still applicable.

If you're a beginner, start with a narrower dildo and gradually work your way up as you become more comfortable. For those seeking a fuller feeling, a wider dildo might be more satisfying. Remember, width can make a significant difference, so choose carefully.

4. Girth

Dildo girth (or circumference) is an indicator of its width, with wider toys having larger circumference. Width is a more straightforward dimension to consider when assessing size, but the circumference of a dildo can be difficult to conceptualize.

Pro Tip: Here's an excellent online tool that allows you to effortlessly switch between circumference and diameter measurements.


What is the Average Size of a Dildo?

Here's a general overview of common dildo sizes:

  • Small: Comparable to one or two fingers in width and relatively short.
  • Medium: Similar to the size of an average penis, offering a balanced experience.
  • Large: For those seeking a more intense sensation, larger dildos offer heightened stimulation.

Dildo Size Chart

Size  Insertable Length  Width (Diameter)
Small 4 to 6 1 to 1.5
Medium 6 to 8 1.5 to 2
Large 8 to 10 2 to 2.5

The average dildo size, based on purchases alone, is around 7.5″ long and 1.5″ in width - slightly larger than an average penis. Interestingly, the most popular dildo size also falls within this range. Through calculations, we can also determine that the average dildo girth is 4.71″. This indicates that individuals generally do not purchase large-sized dildos, but they do tend to opt for sizes slightly above the average penis.

Remember that these are just approximate ranges, and there's no one-size-fits-all answer. People have different levels of experience, comfort, and preferences when it comes to dildo sizes.There are dildos that go up to 20″ and more in length. These products are exclusively designed for experienced users.


Measuring Your Perfect Fit

Knowing the dimensions of a dildo is not sufficient; you must also determine the ideal sizes. We understand your desire to learn how to measure yourself for a dildo, and we will assist you in selecting the optimal size. It is important to note that the 'best dildo size' typically depends on personal comfort and your individual body measurements.

1. Measuring for Vaginal Use:

After lubricating your vagina, gently insert one finger, then gradually add a second. Continue adding more until you reach a state of maximum relaxation and determine your limit. Afterwards, use a soft measuring tape to measure the circumference around your fingers and determine the girth.

To determine the insertable length, insert a long item with a smooth surface. Continue gently pushing until you reach your limit. Use your fingers to mark the point, remove the item, and measure the distance between the tip and your fingers. This measurement represents the insertable length of your dildo.

2. Measuring for Anal Use:

The vaginal and anal measurements are similar, but the anus is more sensitive. Take care when measuring for an anal dildo, as you should be completely relaxed. Using plenty of lube and having a partner assist you is recommended. If you feel any discomfort or pain, it's essential to stop and reassess before continuing.

Pro Tip: Make sure the anal dildo has a flared base to prevent it from getting lost inside your anus.

If you already have a dildo you've enjoyed, you can use a soft measuring tape or a piece of string to measure its length and girth. Compare these measurements with potential new choices to help you gauge the fit.


Conclusions

You’re now ready to select the most suitable size dildo for your needs. Ultimately, comfort is key. If a size feels uncomfortable or causes discomfort, it's best to explore other options that align better with your body's needs.

To recap, if you're a beginner, we recommend starting out with a smaller dildo that's more similar to an average size penis. Or you could try our small realistic dildo, which is just 5.3 inches in size.

If you've used dildos before and feel like you're ready for something a little larger, you can try larger dildos (8" or more). Our most popular Thrusting Dildo is of this size.

What’s more, there’s no right or wrong size. Size is a personal choice, and there’s no wrong or right size.
