What Counts as an Extra Wide Dildo

We call a dildo extra wide when its widest insertable point is 2.5 inches or more across. For comparison, the average erect penis is about 1.46 inches wide, so these are a big step up.

Styles You'll Find Here

  • Thick realistic dildos like the Au Naturel Big John and King Cock 11 inch
  • Dual density Ultraskyn like the Merci Perfect Cock
  • Premium silicone like the Tantus Meat Wave
  • Fantasy dildos that swell to 3 inches at the knot
  • Fisting dildos, double dildos and inflatables you can pump up

Width vs Girth

Width (diameter) is straight across. Girth (circumference) is around. To turn girth into width, divide by 3.14. A 3 inch wide dildo is about 9.4 inches around.

How to Size Up Safely

Go up in steps: 2 inches, then 2.5, then 2.75, then 3. Warm up first, use a thick water-based lube, and let a suction cup base help you control the pace. Stop if anything feels sharp.

Widest Point vs Shaft

Fantasy toys often hit their max width at a knot or bulge, with a slimmer shaft above it. Check the narrowest and widest diameter on the listing so you know how it builds.

Care Tips

Wash your toy with warm water and mild soap or a toy cleaner before and after every use. Use water-based lube with silicone toys, since silicone lube can damage them over time. Let it dry fully and store it in its own pouch, away from direct sunlight.

Frequently Asked Questions

How wide is an extra wide dildo?

Everything in this collection is at least 2.5 inches across at its widest point, and the widest go up to about 3.75 inches.

Are extra wide dildos good for beginners?

Usually not. Start around 1.5 to 2 inches wide and work up. An inflatable dildo is a safe way to test bigger widths.

What lube should I use?

A thick water-based gel. It works with every material and stays put. Use plenty and reapply often.

Do extra wide dildos fit a harness?

Some do, if the base is flared and your harness ring is big enough. Many harness rings max out around 2 inches, so check both.

How did you measure these?

We used the widest insertable diameter from each manufacturer's specs, or converted the listed girth to width. Base measurements don't count.
