When it comes to choosing a dildo, size matters — but only as much as comfort, fit, and personal preference. With so many options available, from petite beginners’ toys to larger, more adventurous sizes, navigating the world of different size dildos can feel overwhelming.
This guide will help you understand dildo sizes, find the right fit for your body, and experiment safely. Whether you’re buying your first toy or exploring new options, this planner provides expert tips, charts, and practical advice.
Why Dildo Size Matters
Size affects not only physical comfort but also pleasure and safety. Using a dildo that is too large can cause pain, while a toy that’s too small might not provide the desired sensation.
Here’s what size influences:
- Comfort & ease of insertion
- Intensity of stimulation
- Ability to use the toy for solo or partnered play
- Compatibility with harnesses or strap-ons
It’s not about the “bigger is better” myth — it’s about what feels good and fits your body safely.
Understanding Dildo Measurements
Dildos are measured primarily by:
- Length – total and insertable length.
- Girth/Circumference – the thickness around the widest part.
- Shape – straight, curved, or contoured for G-spot or prostate stimulation.
📝 Quick Size Guide
| Size Category | Length (Insertable) | Girth (Circumference) | Notes |
|---|---|---|---|
| Small / Beginner | 3–5 inches | 2–3 inches | Great for first-time users or sensitive bodies |
| Medium | 5–7 inches | 3–4 inches | Balanced size, versatile for solo or partnered play |
| Large / Experienced | 7+ inches | 4+ inches | For advanced users, provides intense fullness and stimulation |
| Extra Large | 8+ inches | 5+ inches | Use only with experience and caution, requires plenty of lube and patience |
Tip: Always check both total and insertable length. Total length includes the base or handle, while insertable length indicates how far the dildo can safely go inside.
How to Use a Dildo Size Chart
A dildo size chart is like a personal fit planner. It helps you:
- Compare toys before buying.
- Avoid toys that are too large or too small for your experience level.
- Plan progression from beginner to advanced sizes safely.
Step-by-step guide:
- Step 1: Measure your comfort level. If new, start small.
- Step 2: Consider how the dildo will be used (solo vs. partner, vaginal vs. anal).
- Step 3: Match length and girth to your experience and body anatomy.
- Step 4: Use the chart to compare options before purchasing.
Tips for Trying Different Dildo Sizes Safely
Experimenting with different sized dildos is fun — but safety and preparation are key.
✅ 1. Start Slow
Begin with smaller sizes and work your way up. Your body adapts gradually, reducing discomfort and increasing pleasure.
✅ 2. Use Plenty of Lubricant
Always use a water-based or compatible lube to prevent friction, pain, or injury. For anal use, extra lube is essential.
✅ 3. Relax & Listen to Your Body
Tension makes insertion difficult. Breathe deeply, and never force a dildo in. Pain is a sign to stop.
✅ 4. Experiment with Different Shapes
Some users prefer straight toys; others enjoy curved or contoured shapes for targeted stimulation like G-spot or prostate massage.
✅ 5. Keep Hygiene in Mind
Wash toys before and after use. Silicone, glass, and stainless steel dildos are easy to clean and maintain.

- Shape: Straight or slightly curved
- Purpose: Introductory stimulation, solo exploration
Intermediate Users
- Length: 5–7 inches insertable
- Girth: 3–4 inches

Pro Tip: Even experienced users may prefer smaller sizes for gentle or quick sessions — bigger isn’t always better for every situation.
How to Safely Try New Sizes
Trying different dildo sizes should be fun, not intimidating. Follow these steps:
- Warm up with a smaller dildo or fingers.
- Relax and breathe to loosen sphincter or vaginal muscles.
- Use lube generously.
- Insert slowly in stages if needed.
- Listen to sensations — adjust angle, depth, or pressure.
- Stop if you feel sharp pain; mild stretching discomfort is normal.
This approach helps you progress safely from beginner to larger sizes.
Special Considerations for Anal Play
Anal anatomy requires extra caution:
- Start with a smaller, tapered plug or dildo first.
- Always use a flared base for safety.
- Go slow and use plenty of lubricant.
- Consider relaxing exercises or a warm bath beforehand.
Even experienced users sometimes start smaller for comfort or experimentation.
