sizing 101
choosing a size should feel easy, not intimidating. this guide breaks down insertable length vs total length, why girth usually matters most for comfort, and how to pick a size that feels good for your body — whatever your experience, anatomy, or reasons for exploring.
quick tip: if you’re unsure between two sizes, choose the smaller option first. you can always size up later — comfort builds confidence.
why size matters (more than you think)
when people talk about size, they often focus on length — but for most bodies, girth (thickness) has the biggest impact on comfort and sensation. there’s no “right” size. there’s only what feels right for you, right now.
bodies can also change over time (stress, hormones, medication, ageing, recovery, life). what works today may not be what you want later — and that’s completely normal.
length vs insertable length
total length is the full measurement from tip to base.
insertable length is the part that can actually be inserted (often shorter due to bases, suction cups, or handles).
common comfort ranges (insertable length):
- short: ~10–13 cm
- medium: ~13–16 cm
- long: ~16 cm+
these are not “levels” — just ranges people commonly find comfortable.

girth explained (the big one)
girth is what usually determines intensity. if you’re unsure, starting slimmer gives you more control and reduces the chance of discomfort.
approx diameter guide:
- slim: ~2.5–3 cm
- medium: ~3–4 cm
- thick: ~4 cm+
diameter is a simple reference point — firmness and shape can make something feel larger or smaller than the numbers suggest.
looking for slim + comfortable options? shop by size and filter by “slim” or “gentle” (if available).
starting comfortably (gentle sizing)
if you’re new, returning after a break, recovering, or simply prefer a softer approach, look for:
- slim to medium girth
- softer silicone (more forgiving)
- shorter insertable length
- tapered or rounded tip
firmness & material (same size, different feel)
two toys with the same measurements can feel totally different depending on firmness and material.
softer silicone
- more forgiving
- often easier for comfort-first use
- adapts to movement
firmer silicone / hard materials
- more direct sensation
- less “give”
- can feel larger than the same size in soft silicone
if you’re between sizes, choosing a softer material is often the gentler option.
how to measure (if you already own one)
- measure diameter at the widest point
- measure insertable length (not total length)
- note firmness as well as size
this helps you choose intentionally instead of guessing.
lubrication & compatibility (best practice)
lube supports comfort and reduces friction. reapplying is normal — especially with larger sizes or longer sessions.
- smaller sizes: light water-based lube
- larger sizes: generous amount, reapply often
- silicone toys: generally choose water-based lube

common mistakes to avoid
- jumping straight to large sizes
- underestimating girth
- skipping lube
- assuming “bigger = better”
- comparing yourself to others
your pace is the right pace.
final reassurance
choosing a size isn’t a milestone or a test. it’s simply finding what feels good for you. if you’re unsure between two sizes, start smaller — comfort builds confidence.
