Introduction: How This Massive Dildo Guide Is Organised?

Well, it’s impossible to rank the best dildos as everybody has different desires, needs, and stretching capabilities.

That’s why we arm you with the right knowledge to make good choices, present the best big dildos, and let you choose.

The guide is organized into four sections:

• The Best Big Dildos — these are high-quality & body-safe and realistic dildos that will satisfy most people. Start here.
• Extreme Monster Dildos — here you’ll find large fantasy and animal dildos. Plus, if you’re into depth play the longest sex toys are here.
• The Best Thick Dildos & Girthy Dildos — If your kink is to stretch and challenge yourself to conquer the thickest dildo, this section is for you.
• The Biggest Affordable Dildos (Non-Silicone) — Body-safe silicone sex toys (except glass) are pricey. Large dildos require a lot of materials. PVC, TPE, and skin safe rubber materials are cheap, but they are not 100% body-safe. I know some people still want cheap and are willing to take risks. The price range of these large dildos is $35-$130.

How To Pick The Best Large Dildo For You?

Here you’ll find sex toys starting from 8 inches to even 20–24-inch long dildos.

As for the thick dildos you’ll find 2″ diameter to even 3 to 4-inch fat beasts.

Ninja tip: If you’re missing size in between a weird trick is to put a sock or two on the dildo, and then pull a condom over it. It will be perfect for increasing the girth and get to that next stretching size.

Here’s what you should look out for:

• Look out for Size Choices — some dildos like Mr.Hankey or King Cock have many lengths and girth variations. In the chart, I’ve indicated the sizes of the largest dildo. Visit the dildo creator site to discover other sizes.
• Softness Choices — some premium toy makers like Tantus and Mr. Hankey indicate the softness level of their dildos. All big toys are usually squishy and soft, but for some, you can choose the firmness. If in doubt, go for softer. Sometimes you can also write to toy creators and request a custom choice. Keep that in mind.
• Look for suction cup base & harness compatibility — depending on how you plan to use your dildo lookout for a suction cup base or harness compatibility. Some toys allow adding the Vac-U-Lock hole which can be used for secure use with a harness or adding the suction cup functionality (from Shevibe.com).

What You Should Know About Large Dildos?

These are NOT beginner toys.

These dildos are for size freaks and size queens.

They are for extreme stretching and filling experience.

You can get a long dildo and have an enjoyable play because you don’t need to fit 100% of the toy in.

But pick something too wide and you’ll end up with an expensive display sex toy to only look at.

As for the firmness, all big dildos are soft and squishy. If you’re unsure go for softer.

It helps to think a bit upfront and write down what you’re seeking.

Large silicone dildos take a lot of material and get pricey. 

Mistakes will be costly. So choose wisely.

The Best Large Monster Dildos, Side-by-Side Comparison Chart

Here’s the main chart, of all the best large dildos:

Check the original spreadsheet here.

Let’s explore each selection one by one:

There are only a few companies that make high-quality large dildos.

Tantus was one of the first companies ever to offer big quality silicone toys.

Most people who have been around for a while know about Tantus Hoss, for example.

• Tantus Hoss — this big realistic dildo has 10.5 inches of insertable length. It has a nice tapered head to help with insertion. It doesn’t have a suction cup base but has a flat stable base. Check this video to see how it looks in real life.
• Tantus Fist Trainer — If you’re into fisting, then this toy will help a lot. It comes in two colors — red and black. Those ridges near the base are fun. Here’s a helpful video showing how soft SuperSoft Tantus dildos are.

Next, Mr. Hankey Toys…

Mr.Hankey Toys offer both fantasy big dildos and realistic dildos that are super high quality and come in gigantic sizes.

You can choose between four sizes and two firmness levels. 

If you write to them, you can get even a custom firmness.

The chart below indicates the largest dildo sizes (check product page for smaller toy sizes).

(Use their search feature to find the individual dildos).

• Largo Extremely Long Dildo — This is the longest dildo by Mr. Hankey. It comes 16 inches in length and 3 inches girth. Here’s the video showing this huge dildo in real life.
• Big Daddy XXXL — while we didn’t put this dildo in the fat dildo section, it might as well. The largest version goes from 3.1″ to 3.8″ in diameter while also being 14.5″ insertable length long. The name doesn’t lie — it’s a big daddy. But you’ve got four sizes so choose accordingly.
• Cyrus King XXXL ( ⭐Our Huge Realistic Dildo Choice) — This huge dildo features nicely defined head, realistic veins, and has balls at the base. It’s modeled after Cyrus King pornstar penis. The biggest version is both long and wide, however, the smallest Cyrus King has 7″ insertable length. Very manageable.

Don’t be fooled by pictures, these dildos are huge. 

Make sure you measure carefully. Just check out all four sizes of Big Daddy dildo.

See the size of a guy and the size of a can? 😉

Finally, if you like steel, glass, vibrations or realistic large dildos, check this out:

You want soft squishy toys that have a lot of give to be able to successfully insert that humongous dildo in.

• Vibrating G5 Big Boss — while this is not a massive dildo, it is the biggest and fattest quality vibrating dildo created. It’s nicely curved for G spot stimulation, and you can play with it for 2–4 hours. Use it as a vibrator or as a dildo — 2 in 1. Check this video review to learn more.
• Njoy Eleven Extra — Njoy makes the highest quality medical grade stainless steel sex toys. It is a heavy 1250g toy. Choose it if you’re a sex toy aficionado, already love smaller nJoy toys and love the weight and size that makes hitting the spot effortlessly. Check this video to see this beast in real life.
• Vixen Outlaw ( ⭐Large Dual Density Dildo) — this is the largest dildo from Vixen. While it’s not huge (9 inches insertable), it’s one of the biggest dual-density affordable dildos you’ll find. Dual-density offers the most realism since it has an inner rigid core and outer squishy layer. This makes the dildo feel almost the same as a real penis.
• Double-Ended Glass Dildo —while the glass is rigid, it also makes it great for pressing that P or G-spot. For 9 inches insertable length you’ll pay only $30 (cheapest non-porous option). You can insert it from both ends and each has a different texture. While not for everyone, some love the temperature play and the fact that the glass is quite light in weight.

Every toy is unique in its own way, and the manageable size should make an enjoyable experience for anyone. 

No crazy girths, no crazy lengths here, just larger than average. But keep reading 😉

Extreme Monster Size Animal Dildos, Side-by-Side Comparison Chart

Here’s the big fantasy, animal and monster dildo chart, but few notes before you dive in deeper:

Check the original spreadsheet here.

First, let’s check some oversized and challenging animal dildo shapes. 

Like: extreme dog dildo? 

Or what about horse dildos? (we have an in-depth guide).

There is an expression after all “hung like a horse”.

Again, Mr. Hankey’s Seahorse and Centaur rule with size and customization.

But Sinnovator company also has a few realistic horse and dog dildo shapes.

• Hankey’s Seahorse XXX Dildo —this is an ultimate monster fantasy dildo and you’ll love those knots and ridges — it’s insane! It comes in 5 sizes and 2 softness choices and a great price for its size and weight. Check the video on how this toy looks in reality.
• Hankey’s Centaur XXL —this was our #1 most realistic horse dildo selection. What makes horse dildos unique is that they usually have 3 level size increments making them great for stretching slowly to wider levels. Centaur has a smooth tapered head and detailed ridges that amplify the experience. 
• Sinnovator Stallion Horse Dildo — another version of horse dildo. It has a wider base with balls offering a little more stability. You can customize more colors there, but you cannot change the firmness.
• Hellhound Dog Dildo — this option is for animal dildo and girth lovers. It’s quite realistic and girthy. A more fun shape after you’re bored from traditional realistic dildos. That tip is lots of fun to start with.

If there would be one monster dildo that’s been the most loved by size freaks Hankey’s Seahorse is the one. 

Seahorse has both a unique shape and enormously challenging sizes. Here’s how it looks like in the video.

Here are two fun fantasy dildo shapes. 

Tantus has made quite fat and long Amsterdam dildo that people love, and GeekySexToys carry tons of fantasy dragon, tentacle, and unicorn horn dildos.

• Amsterdam XL — this is a common choice for people who’ve learned other Tantus products like Tantus Hoss. It has a challenging girth right from the start and 10.5″ insertable length is quite a size to conquer. Watch this video to see this dildo in real life.
• Unicorn Horn Fantasy Dildo — Geeky Sex Toys make fun and colorful sex toys for ehem.. — geeks. They have dildo swords, Pikachu butt plugs among other things. There are some bigger toys to have you challenged too. Dildo tapered shape makes for really nice stretching and warm-up for bigger toys.

The video here demonstrates how Unicorn Horn dildo looks in real life. Their quirky approach is nicely presented in those videos. 

The only downside is that they are based in Australia making delivery a bit longer than impatient kinksters would like.

Finally, here are a few of the longest dildos for extreme depth play.

Maybe technically it doesn’t fit in the monster section, but that Slink looks pretty out of this world.

Anything over 12″ in the butt is extreme… But the biggest toys here go from 23.5 inches to even 40 inches for a colon snake.

SquarePegToys company is famous for its super soft and high-quality extreme anal sex toys.

• SquarePeg Slink — this sex toy is for serious bum sluts. It’s softness guarantees the best feeling you’ll ever have with any anal toy. It’s costly, but worth the gold. This eel slips in easily and will allow you to experience depth play sensations without much work on stretching.
• SquarePeg Colon Snake — Coming in sizes — 15″, 20″ to 38″ this depth probe is for really advanced players. Anything over 12″ in the butt is. While Slink can be used by intermediate users, colon snake usage will require getting passed that hard bend of Sigmoid Flexure that shouldn’t be attempted by people who are new. The sex toy itself is super soft and is the best tool to use to go really deep.

Watch this video to see Slink in action:

The Best Thick Dildos & Girthy Dildos , Side-by-Side Comparison Chart

Vaginally there is a hard limit of around 10 inches, and then there’s no surpassing the cervix.

But you can always go girthier and have fun stretching goals, even though most stretching enthusiasts actually work on expanding those butt sphincters.

Remember to size up in 0.25″ increments:

• 2-inch girth is already pretty challenging.
• 2–3 inches is where most stretching enthusiasts lie
• 3–4 inches is the widest that any human can possibly take, and it will take A LOT of work. 

Check the original spreadsheet here.

Our favorite is The Rabbit Mr. Hankey dildo because it comes in 4 sizes, you can pick the firmness level, and the whole shape is nicely tapered to help with a smooth stretching.

But here’s more on each selection:

• Buck Vixskin — while all the other selections are very girthy, this is something a lot more manageable. Buck is made from dual-density silicone giving ultra-realistic and stretching experience. It even has a nice curve for G-spot stroking.
• Mr. Universe — this stretching dildo has great proportions — big fat head and then even thicker base. People love to go between this and Tex plug. A+ toy for size queens, a nice girthy fella.
• Tex Anal Plug — This is an enormous 3″ girth plug for advanced users. If you’ve been looking to make a gaping reality, this is one way to do it. Unfortunately, it’s rounded base doesn’t make for good long-term wear, look for SquarePeg T-base egg plug for that.
• Rivetor Split Peaches — this big dildo is both long and girthy, but it’s great that the tip is tapered to get you started easier. It has a bit of a curve for G-spot targeting and those bumps add an interesting touch. Here’s a video review (not great quality) explaining more about this dildo.
• The Rabbit ( ⭐Our Thick Pick) — short and ultra-wide dildo that has a nice curve and smooth increase for nice opening. Perfect for girth lovers as this dildo is wide but short. Choose a softer option to be able to conquer bigger toys faster.

Extreme Size & Affordable (Non-Silicone) Dildos, Side-by-Side Comparison Chart

Well, this is my least favorite section (unless you buy these dildos as a gag or temporary trial option).

These are the oversized dildos that historically came first. 

When people were less educated they were excited to get cheap, huge dildos, and they didn’t care as much about material. Big sex toy companies like Pipedreams and Doc Johnson capitalized on this trend.

TPE, PVC, Skin Safe Rubber — these materials are a lot cheaper than silicone, but they come at a cost.

Some people have bad allergies to them and these materials are porous, which means that over time these toys will harbor bacteria no matter how hard you try to clean them.

On top of that, you cannot boil them since they melt in higher temperatures, contrary to silicone.

But hey, they are affordable. 

First of all, here are a few cheaper dildos that focus on length and have manageable girth:

King Cock has so many size options starting from 7.5-inch length to even 14 inches that cost only from $45 – $130.

• King Cock by Pipedreams (⭐Budget Pick) — you can get 8.5″ realistic dildo for $45, pretty unbeatable. Then there are tons of color, size variations in going from 8,9 inches, 12 inches and, of course, 14 inch dildos. With balls, without, most has a strong suction cup and even kits for harness compatibility. Check the videos on product pages for more.
• Belladonna Magic Hand — if you strive for fist realism, this is as real as it gets. There is a bit of smell to the TPE, and sex toy details make it hard to clean, but it’s a large and cheap toy.
• Dick Rambone — it’s made from Doc Johnson Sil-A-Gel material, but it’s still rubber which is porous. Some complain that the texture is abrasive and has an odd smell, but again the price and the size (13.5 inches insertable) are unmatchable. Doc Johnson also makes a popular John Holmes 12 inches big dildo, but again it’s made from PVC material. That’s bad.

Then here are the cheapest girthiest dildo options. 

3.1 inch and 3.2-inch girth is nothing to scoff at. 

It’s huge.

• King Cock Chubby — This is a truly fat dildo. 3.2″ diameter and a suction cup addition ensure that you’ll have the squat of your life. It’s actually quite long too and 7″ insertable length will make you love every inch of its girth.
• American Bombshell — this is a famous butt plug even despite its material. Material is quite firm, yet flexible enough. The neck is very thick and will satisfy the seasoned pro though some mention that it’s a bit smaller than they had hoped. But could be a nice addition to your smaller toy family.

Quick Tips On How To Use Big Dildos

If you’re looking for gigantic toys probably you’re already quite advanced, but still, I feel like it’s our duty to give some advice for safe and enjoyable usage.

A few basics that you must know:

• there is no such thing as too much lube
• don’t start with the big toys. make sure you warm-up and stretch with smaller toys. Even more important if you’re going for girth.
• the more aroused you are the easier and more enjoyable the stretching and filling will be. Use a vibrator on the clit or stroke your penis as you are working the toy.
• patience is key. It takes a long time to stretch especially the girth anally. You gotta take it slow and listen to your body.
• relaxation and deep breathing help a ton.

When considering the bigger toy try to go in 0.25 inches diameter sizing up increments. 

Know that vaginally there is a hard limit of 10 inches. This is when you gotta hit the cervix and only childbirth can increase this limit.

Then anally if you go anything deeper than 12 inches make sure to do comprehensive research on the rectum anatomy. 

The deeper you go, the more dangerous the play becomes.
