Mr. Kikuchi’s Size Guide
If this is your first Kikuchi toy, you do not need to understand every product family before choosing.
Start with one question:
What size are you already comfortable with?
Use a Toy You Already Know
Find the widest toy you can use comfortably and repeatedly. Check its maximum diameter—the width at its widest point.
That number is a better starting reference than the largest toy you have ever managed once.
Use the Kikuchi Size Letters as a Rough Reference
Kikuchi uses size labels to organize the range, but the exact measurements vary by shape. Treat the labels as approximate positions within the Kikuchi range, not as universal industry standards.
· XS: generally below about 4.5 cm maximum diameter
· S: roughly 4.5–5.5 cm
· M: roughly 5.5–6.5 cm
· L: roughly 6.5–7.5 cm
· XL and above: generally above about 7.5 cm
Always check the actual measurements of the specific product and size before ordering.
If You Are New to Larger Toys
Within the Kikuchi range, XS is usually the most approachable place to begin if you are unsure of your current size. If you already use conventional adult toys comfortably, S may be the more natural starting point.
Your first purchase does not need to prove anything. It should give you a size you can actually learn from and use again.
If You Are Between Two Sizes
Choose the smaller one.
You can always move up later. A size that feels controlled and repeatable gives you more useful information than a larger size you can barely manage.
Do Not Compare Size Letters Alone
An S Panther and an S from another product family may not have identical measurements or feel the same.
The size letter tells you roughly where the product sits in the range. The actual dimensions and the shape tell you what you are buying.
Shape Can Change the Difficulty
Two toys with the same maximum diameter may still feel very different because one tapers slowly, one reaches its widest point quickly, one stays thick for longer, or one is firmer.

When Should You Move Up?
Using a larger size once does not automatically mean you need the next size.
Move up when your current size feels familiar and controlled: you understand the shape, you know how your body responds to it, and you are no longer fighting the size.
Choose the size that makes sense now. There is no need to plan five steps ahead.
