Dildo Size Guide: How to Read Size Charts and Choose Length & Girth (6" to XXL)
Most product titles list two numbers, like 8.6" x 2.2". The first is length, the second is diameter (width). Getting size right is the single biggest factor in whether a toy feels good or ends up in a drawer. This guide explains how to read those numbers and what each size range actually feels like, so you can pick with confidence.
How dildo measurements work
- Total length — tip to base. Includes the part you can't insert (the base or balls).
- Insertable length — usually 1–2 inches shorter than total. This is the number that matters for depth.
- Diameter — width at the thickest point. Multiply by ~3.14 for circumference (girth) if you prefer that measure.
Rule of thumb: length controls depth, diameter controls fullness. Beginners almost always overestimate the length they want and underestimate how much diameter matters.
Size-by-size breakdown
| Size | Best for | Notes |
|---|---|---|
| Small / under 6" | First-timers, sensitive users | Easy to control, low pressure. |
| 6 inch | Everyday comfortable size | Hits the G-spot/P-spot without going deep. |
| 7 inch | Stepping up from beginner | Most popular "realistic average" range. |
| 8 inch | Experienced, want more depth | Watch the diameter — 8"+ often gets thicker too. |
| 9 inch / 10 inch | Size enthusiasts | Go slow; use plenty of lube. |
| 11 inch / 12 inch / Huge / XXL | Advanced players | Girth is the real challenge here, not length. |
Girth & thickness: the number people ignore
A toy that's 1.2" wide and one that's 2.2" wide feel like completely different products even at the same length. If you're new, prioritise a slimmer diameter (1.2"–1.5") like the Kris 6.2" x 1.3" over a thick "short & fat" build. Once you're comfortable, thicker toys deliver more fullness and stretch.
Choosing your size, step by step
- Pick your insertable length based on the depth you enjoy — start near 5–6".
- Choose a diameter you can comfortably accommodate; round down if unsure.
- Match the base to how you'll use it (suction cup for hands-free, flared base for a harness).
- Read the gallery photos — a hand or banana reference tells you more than the spec line.
FAQ
Is insertable or total length more important?
Insertable length, every time. It's the part that affects depth. Total length just tells you the overall footprint.
What size should a beginner buy?
Around 5–6" insertable and 1.2–1.5" diameter. See our beginner's guide for the full reasoning.
Does a bigger toy mean better?
No. Comfort beats size. The right toy is the one you'll actually reach for.
