Understanding the Measurements
| Term | What It Means |
|---|---|
| Total Length | The full length of the product end to end, including any non-insertable base or handle. |
| Insertable Length | The portion of the product that's actually meant to be inserted — usually shorter than the total length. |
| Diameter | The width at the widest point, measured straight across. |
| Circumference | The distance around the widest point — useful if you're more familiar with this measurement than diameter. |
Always check insertable length rather than total length when comparing sizes — it's the number that actually matters for fit.
Choosing a Size as a Beginner
If you're new to a product category, it's generally more comfortable to start on the smaller-to-moderate end of the size range and work your way up over time as desired, rather than starting with the largest option available. Beginner-labeled products are typically designed with this in mind — slim profiles, tapered tips, and gradual width increases.
Comfort Tips
- Take your time — comfort improves with relaxation and patience.
- Use a generous amount of compatible lubricant (see our Lube Compatibility Guide).
- For anal products specifically, always choose designs with a flared base for safety and easy retrieval.
- If something feels uncomfortable, stop and reassess — discomfort is a sign to slow down, not push through.
Sizing for Couples
If you're shopping with a partner, consider products with multiple interchangeable attachments or adjustable intensity, which let both partners find their preferred fit without needing to buy multiple separate products.
