Sizing, explained
How to choose the right size sex toy
Buying a toy online means guessing what “18 cm” actually feels like. The easiest fix is to measure something you already enjoy, whether that’s a toy or a partner, and shop within a centimetre or so of it. Want more? Go up gradually. Most people find width makes a bigger difference than length.
Dildo and vibrator sizes
Across the dildos we stock, the middle of the range is about 16.5 cm insertable and 4 cm wide. Vibrators sit a bit smaller, around 12.5 cm by 3.6 cm. Under 3 cm wide feels slim, 4 to 4.5 cm feels full, and over 5 cm is for size queens. Browse dildos and vibrators.
Butt plug sizes
For a first plug, look for something under 2.5 cm wide with a flared base and plenty of lube. Training kits with three sizes make it easy to work up. Everything we sell for anal play is in anal toys.
Cock ring sizes
Fixed rings are sized by inside diameter. Measure around the base while soft and divide by 3.14 to get it. Stretchy and adjustable rings fit most bodies, so they’re the safe pick if you’re unsure. See all cock rings.
Lingerie sizes
Measure bust, waist and hips in centimetres and match them to the brand’s chart rather than going by your dress size alone. Stuck between two? Size up for anything fitted. Shop lingerie.
Size questions
What size dildo should a beginner buy?
Something around 12 to 15 cm insertable and 3 to 3.5 cm wide is a comfortable start for most people. Silicone with a bit of give is kinder than glass or metal while you work out what you like.
What size butt plug is best for beginners?
Under 2.5 cm at the widest point, with a flared base so it can’t slip in too far. Use plenty of lube and go up a few millimetres at a time.
How do I measure for a cock ring?
While soft, wrap a strip of paper or string around the base (and behind the balls for a cock and ball ring). Measure the length in centimetres and divide by 3.14 to get the inside diameter for a fixed ring. Round up, never down.
How long can I wear a cock ring?
Twenty to thirty minutes at a time. Take it off straight away if it hurts, or if things feel numb or cold or look blue.
What is the average penis size?
A 2015 review of more than 15,000 men found an average erect length of 13.1 cm and an average girth of 11.7 cm around.
Do lingerie sizes run the same across brands?
No. Fantasy Lingerie and Penthouse use different charts, and one size pieces cover a range. Measure yourself and check the brand’s chart above, or the fit line on each product.
