TL;DR: Quick Answer
Shaft dildos come in a clear size ladder from slim 5.5" beginners to bold 9.5" models, so you can upgrade to a more realistic dildo without guessing whether it will feel too small or way too big.
- Think in size “bands”: up to ~1.4" wide = small, ~1.5–1.7" = average‑plus, ~1.8"+ = big.
- Match those bands to Shaft J 5.5"–6.5" for gentle upgrades, A 7.5"–8.5" for fuller realism, and A/N 9.5" for size‑lovers.
Key Takeaways: Shaft Dildos Size Guide Features
- Simple small / average / big framework tied to real Shaft models and measurements.
- Beginner‑friendly options (J 5.5" and 6.5") plus intermediate and advanced picks in the same Flexskin range.
- Clear advice for upgrading from basic toys to Shaft without overdoing size.

When you’re upgrading to a more realistic dildo, size is usually the biggest anxiety point. You want something that feels exciting and new, but not so large that it sits in a drawer because your body never really got used to it.
This size guide breaks Shaft dildos into simple bands—small, “average‑plus,” and big—and ties them directly to specific models in the Shaft dildos collection. It also connects with the hyper‑realistic upgrade guide, the best Shaft dildos for upgrading page, and the Flexskin realism explainer so you can see size, feel, and product picks all in one system.
How to Read Dildo Sizes Without Freaking Out
Length vs Insertable Length vs Width
Product pages usually list a total length and sometimes an insertable length. For comfort, focus on:
- Insertable length: the part that actually goes inside your body.
- Maximum width: roughly how thick it will feel at the widest point.
- Shape: straight vs curved, smooth vs more textured.
Small, Average, and Big: A Simple Framework
Everyone experiences size differently, but many shoppers find this breakdown helpful:
- Small: up to about 1.4" wide – gentle, beginner‑friendly, great for warm‑up or anal beginners.
- Average / average‑plus: about 1.5–1.7" wide – feels full but not overwhelming for most people used to penetration.
- Big: around 1.8" and above – for more experienced users or size‑lovers.
Why Shaft Makes Size Easier to Understand
Shaft’s lineup uses consistent shapes and materials across different sizes, so once you find a Shaft that feels good, it’s easier to move one step up or down. You don’t have to juggle different brands, different firmness, and wildly different shapes just to get a sense of what “bigger” or “smaller” will feel like.
Small Shaft Dildos: Gentle, Realistic Upgrades
Who Small Shaft Dildos Are Perfect For
Small Shaft dildos are ideal if you’re:
- New to penetrative toys or coming from very slim jelly or bullet‑style toys.
- Curious about realism and Flexskin but not ready for a big size jump.
Best Small Shaft Picks (Up to ~1.4" Wide)
- Shaft Model J Flexskin Liquid Silicone 5.5" Dong – Mahogany Gentle length, slim width, and a realistic look that makes it feel like a true upgrade from basic toys. Shop Shaft J 5.5" Mahogany
- Shaft Model J Liquid Silicone 6.5" Dong – Oak Adds a bit more insertable length while staying slender, great if you’re comfortable with fingers or mini toys. Shop Shaft J 6.5" Oak
- Shaft Model J Liquid Silicone 6.5" Dong – Mahogany Same proportions as the Oak version in a rich Mahogany tone, ideal if colour is part of your fantasy. Shop Shaft J 6.5" Mahogany
How Small Shaft Dildos Feel
You still get full Flexskin dual‑density realism—soft outer layer, firm core—but in dimensions that let your muscles relax and learn the sensation. They’re particularly good if you’re also working on comfort, pelvic floor relaxation, or getting used to penetration again after a break.
Average‑Plus Shaft Dildos: The “Just Right” Zone
Who Average‑Plus Shaft Dildos Are Perfect For
Average‑plus Shaft dildos suit you if you:
- Already enjoy average‑sized silicone dildos or penises and want more realism and fullness.
- Want one dildo that can be your everyday favourite for solo play and strap‑ons.
Best Average‑Plus Picks (~1.5–1.7" Wide)
- Shaft Model A Liquid Silicone Dong With Balls 7.5" – Oak A classic “realistic boyfriend” size with balls and suction, great for most experienced users. Shop Shaft A 7.5" Oak
- Shaft Model J Liquid Silicone Dong 8.5" – Mahogany For people who like deeper penetration with a still real‑world, manageable width. Shop Shaft J 8.5" Mahogany
- Intermediate step‑up: Shaft A 9.5" Pine Right on the border between average‑plus and big for some bodies, and a strong choice if you already find medium toys easy. Shop Shaft A 9.5" Pine
How Average‑Plus Shaft Dildos Feel
These sizes tend to feel pleasantly full, especially with Flexskin’s soft outer layer and firmer core. For many people, this band is where you get maximum realism and satisfaction without needing extensive warm‑up every time.
Big Shaft Dildos: For Size‑Lovers and Power Users
Who Big Shaft Dildos Are Perfect For
Big Shaft dildos are a good fit if you:
- Already own and enjoy larger toys and want to upgrade to something more realistic and body‑safe.
- Love the feeling of being very full and don’t mind taking your time to warm up.
Best Big Shaft Picks (~1.8"+ Wide)
- Shaft Model A 9.5" Liquid Silicone Dong With Balls – Mahogany A large, straight Shaft with realistic sculpting and a bold presence. Shop Shaft A 9.5" Mahogany
- Shaft Model N 9.5" Liquid Silicone Dong With Balls – Black Big and curved, designed to deliver a lot of fullness plus focused G‑spot or P‑spot contact. Shop Shaft N 9.5" Black
- Big straight classic: Shaft A 9.5" Pine Same bold dimensions in a lighter shade, ideal if you want a large straight shaft that still looks realistic. Shop Shaft A 9.5" Pine
How Big Shaft Dildos Feel
With Flexskin, large toys feel heavy, warm, and surprisingly forgiving on the surface while still delivering intense fullness. These are not “starter toys”—they’re best approached with plenty of water‑based lube, gradual warm‑up, and listening carefully to your body.
Strap‑On and Pegging Sizes: Where to Start
Beginner Pegging and Strap‑On Sizes
- J 5.5" Mahogany – ideal for first‑time anal play and pegging, where slim size reduces anxiety.
- J 6.5" Oak / Mahogany – a bit more length, still slim enough for most beginners with proper warm‑up.
Intermediate Strap‑On Sizes
- A 7.5" Oak – excellent “realistic” strap‑on size that feels natural for many receivers.
- J 8.5" Mahogany – deeper and more intense for experienced partners.
Advanced Strap‑On Sizes
- A 9.5" (Pine or Mahogany) – heavy and full, best left until both partners are sure bigger sizes feel good.
- N 9.5" Black – combines big size with curve, which can be incredible once you’re comfortable at that level.
Step‑by‑Step: Choosing Your Shaft Size
Step 1: Compare to What You Already Use
Look at your current favourite toy or experience and ask: does it feel too small, just right, or a little too much? Even if you don’t have exact numbers, that “body sense” tells you whether to stay in the same band or move one step up or down.
Step 2: Decide if You Want to Prioritize Comfort or Intensity
- If comfort and confidence are your priority, stay in the small or lower average‑plus band.
- If you crave intensity and don’t mind more warm‑up, aim for upper average‑plus or big.
Step 3: Pick 1–2 Shaft Models to Start With
One great approach is to pick one “safe” Shaft and one “ambitious” Shaft. For example, a J 6.5" for everyday comfort and an A 7.5" or 9.5" as a stretch goal once your body is ready.
Step 4: Revisit Size After a Few Sessions
Your comfort and preferences can change with time and practice. After a few sessions with a new Shaft, you may find that what once felt “big” now feels comfortably full, which can make stepping up to the next size feel much more accessible.
Who It’s For
This size guide is especially helpful if you:
- Are upgrading from basic toys and want to understand how Shaft sizes will feel before you buy.
- Already have a Shaft dildo and want to choose your next size with more confidence instead of guessing.
Frequently Asked Questions
How do I know if a Shaft dildo will feel too big for me?
Use your current experience as a reference. If average‑sized toys sometimes feel like “a lot,” stay with the small or lower average‑plus Shaft band (J 5.5"–6.5" or A 7.5"). If you already enjoy fuller sensations, stepping up to J 8.5" or A/N 9.5" can be a satisfying challenge rather than a shock.
Can I move from a small Shaft dildo to a big one right away?
It’s usually more comfortable to move gradually. Many people start with a small or average‑plus Shaft, give their body time to adjust, then add a bigger size later. That approach lets your muscles get used to more realistic fullness without risking strain or discouraging experiences.
Are the measurements the same across all Shaft dildos?
Each model has its own measurements, but the lineup is designed so sizes scale in a fairly predictable way. That makes it easier to use one Shaft as a reference point when choosing your next one. Checking product descriptions and comparing lengths and widths can help you make a more informed choice.
Do I need different Shaft sizes for vaginal vs anal play?
Some people use the same Shaft size for both, while others prefer smaller, slimmer sizes for anal play. If you’re new to anal penetration, starting with the smallest Shaft models (like J 5.5" and 6.5") can make the experience more comfortable, especially when combined with plenty of water‑based lube and slow, patient exploration.
Where can I see all Shaft sizes in one place?
You can compare all sizes visually and by specs in the Shaft dildos collection. For more guidance on choosing by feel and experience, the hyper‑realistic upgrade guide, the best Shaft dildos for upgrading, and the Flexskin realism guide all work together to give you a complete picture.
