Dildo Size Guide - How to Get the Right Length and Width:

Choosing the ideal dildo size can feel intimidating, especially if you’ve ever asked yourself, “Is this too big?” or “Will this feel good for my body?” You’re far from alone. At Naughty North, we help people find toys that match their comfort, desires, and anatomy every day.

Here’s the honest truth: bigger isn’t always better. The most satisfying fit comes from smart size choices that feel natural and pleasurable for your body. This guide breaks down how to think about both length and width so you can shop with confidence.

Why Size Actually Matters

Your toy’s dimensions do more than determine how it looks, size affects:

• How full the toy feels during use

• Ease of insertion and comfort

• Control and maneuverability

• What internal pleasure zones you can reach

• Whether your experience feels smooth or uncomfortable

The right size makes exploration intuitive and fun — the wrong one can feel awkward, frustrating, or even painful. Your pleasure deserves something that fits you.

Step 1: Think About the Sensation You Want

Before jumping to measurements, consider what feeling you’re after. Most people fall into one of these categories:

❍ Gentle & Beginner-Friendly

• Look for a slender width

• Moderate insertable length

• Smooth shapes that feel easy and comfortable
  Great for warming up, learning your preferences, and building playroom confidence.

❍ “Filled” & Stretch-Forward

• Prioritize girth over length

• A slightly thicker toy gives more pressure and fullness
  A sensation of fullness comes more from width than depth.

❍ Deeper Internal Sensation

• Longer insertable length lets you explore depth

• Around 7″ insertable length is a manageable jump for many with basic experience
  Avoid picking depth just for looks — too much can hit the cervix in an uncomfortable way.

❍ Versatile Everyday Toy

• Choose a middle-of-the-road size

• Around 5.5–6″ of insertable length with ~1.5″ width
  This resembles average body proportions and works well in most scenarios.

Length vs Width — What’s the Difference?

A common misconception is that length is the main game — but for most people, width makes the biggest difference in sensation.

✔ Length

• Determines how deep a toy can reach

• Affects how thrusting feels and which positions work best
  But only the insertable length (not total length) matters during use.

✔ Width

• Dictates the feeling of fullness and stretch

• Affects comfort and whether you need extra warm-up
  Even small changes in width can have a noticeable effect on sensation.

💡 Pro Tip: If you’re unsure, size down in width before size down in length. Too much girth too fast is the #1 reason people are unhappy with their toy choice.

How to Estimate Girth

Toy packaging often only lists width (the straight-across measurement), but you can estimate girth, the circumference around the toy, because that’s what your body actually feels.

Formula:
👉 Girth ≈ Width × 3.14
For example, a dildo that’s 1.5″ wide is about 4.7″ in girth.

Tips for Choosing Width Without Guesswork

Here’s how different width ranges typically feel:

• Slim (≤1.5″ wide): Easy entry, gentle pressure — great for beginners

• Medium (1.6–1.9″): Satisfying fullness and versatile use

• Thick (2″+): Stretch-forward and intense — best with experience

There’s nothing “advanced” about discomfort. Your body will tell you what feels right.

Shape, Curve & Texture Change the Experience

Even toys with the same measurements can feel different:

• Smooth vs. Textured: Texture adds friction that increases intensity

• Straight vs. Curved: Curves can target deeper pleasure zones

• Tapered Tips: Easier entry and gentler sensations

All of these features influence comfort and stimulation beyond just size.

Picking Sizes Based on Play Style

Solo Sessions

• Mid-range length often feels best because you control everything

• You don’t need extreme depth unless you want deeper sensation

Partner Play

• A slightly longer toy may help hit angles better

• But comfort and control still guide best results

Strap-On Play

• Size really matters here

• Too long or too wide can be hard to manage through a harness
  Go for moderate length and easy-to-hold shapes so both partners have a smooth experience.

“Will It Hurt?” How to Make Any Size Feel Better

Pain isn’t a badge of honour, it’s a signal your body needs something gentler. Here’s how to make any size feel more comfortable: 

1. Use plenty of lube — more than you think you need

2. Warm up first with fingers or a smaller toy

3. Go slow — excitement often rushes ahead of comfort

4. Choose something you can control

Pleasure should feel good, not like a test you must pass.

Staff-Approved Starting Advice

If you truly have no idea what size to pick, start here:

• Moderate length

• Manageable width

• Body-safe material

• Inviting shape (not intimidating)

This is the sweet spot where most people find their favorite toy. And if you want to go bigger later, that’s totally fine! 

Final Word: The Right Size Is Personal

There’s no universal “perfect” dildo size — just the one that feels right for you. At Naughty North, we believe in:

✔ Pleasure that’s comfortable
✔ Exploration without pressure
✔ Confidence that grows with experience
✔ Toys that match your body, not challenge it

Whether you want something cozy and petite, satisfyingly full, or delightfully bold the right toy exists for you.
