Sandworm size chart

FOH there's no way a graboid is bigger than a sarlacc.

Edit:

OK with some web searchin', I got some rough guesses as to the size of each one (spoilers: OP's chart is so far off it's probably a troll):

Graboid. They fit in a flatbed truck bed. The Tremors wiki puts them at 9m long and 2m wide, making them approximately 2 rhinos big.
Beetlejuice sandworm. There's an amusing behind-the-scenes photo of the set construction for the sandworm scene, which has a model sandworm next to a model door, the door they step out of when they try to leave the house. The sandworm's visible body is perhaps 2x the height of the door, and most of it is underground. Figuring a 2m door height, we can estimate this guy is about 20m long. Not something you want to meet in the dark, but only about 4-8 rhinos big.
Sarlacc. A real big boy, about 100m in length, unknown average diameter but the artists' depictions I've seen make it look like roughly 30-50m in circumference, or about 12-16m in diameter. Probably 400 rhinos big.
Shai Hulud. One of these things eats an entire spice harvester in one bite. Basically doesn't even belong on this chart unless this is a log scale, these guys are 15-25 meters in diameter, big enough to eat the flatbed truck and the graboid without even noticing it swallowed them. Probably a mile or more in length. Given the current state of the rhino population, a Shai Hulud almost certainly outweighs all rhinos put together.

It should be noted that while the sarlacc's diameter seems to put it in punching range of the shai hulud, two things really set the Dune sandworms apart:

Basic biology math. The mass of the creature increases with the cube of the diameter, so a ~2x increase in diameter for the shai hulud translates into a mass ratio of 8x.
Length. Shai Hulud are much more wormlike than Sarlaccs. That means they're far, far longer relative to their diameter.

Put these together and you can be pretty sure that a sarlacc to a dune sandworm is like a puppy.

EDIT 2:

I am pleasantly surprised to learn that some species of rhino have many thousands of individuals. I believe they would, in fact, outweigh a single Shai-Hulud.

Thank you for your service
Good work, researcher!
In the far future, "Our time scientists discovered debates about worm sizes. The basic unit for worm measurement was a rhino." ... "What is 'a rhino's?" ... "We are unsure still. But they didn't have many."

Everything about this is wrong.

Graboids are the smallest, maxing out at 10 meters in length.
The Sarlaac pit is just the mouth. The actual Sarlaac is 100 meters long
The Beetlejuice Sandworm has a head slightly larger than an average door, so about 1 meter wide.
Shai Hulud get up to 1000 meters in length (pre-Brian Herbert Lore) and around 40-50 meters wide.

Fuck yeah thank you.
- Right? I came here to angry comment and seen I wasn't alone.
Lisan Al-gaib!

Graboids are not that big, they can fit on a flat bed trailer.

Really I think the scale is off. Dune's sand worms are massive
- Also feels like you could fit a flat bed trailer inside of the Sarlac Pit with ease, right?

Where is the Alaskan Bull Worm?

Considering that in a picture I found on the spongebob wiki the alaskan bull worm is five Sandys in height, and that the american red squirrel with tail is long from 25 to 35 cm according to wikipedia, with the tail almost as long as the body, I can approximate Sandy as being 15cm tall. Therefore the alaskan bull worm is approximately 75 cm in diameter, (30 in. in stupid units) putting it first in the line as the smallest

This is waaay off. Also missing the D&D purple worm...

And the ones from trigun

The worm in beetlejuice is simply called a Sandworm

Wait a second there, there was no beetle juice in Beetlejuice
Sandworms of Saturn

So, the sarlacc. The bits of it we see in the movies, are its mouth (the pit with the spiky stuff,) and its (apparently beaked) tongue.

The sarlacc is probably quite a bit larger. (Maybe not dune sand worm big.)

How do sarlaccs multiply? They are not very mobile, so I assume some sort of pollen/spore situation. So it's "mouth" might also be it's genitals
- The wiki says spores. Good guess!
- I dunno. I’d have to either be spores or parthenogenesis. Given their size they can’t be that common,
I would guess it's exactly Dune sandworm big, in that it's taken from Dune directly. Almost certainly it started as the same creature.
- I’d say not, because they’re apparently large enough that a Krayt dragon can fit into the cavity left behind after eating one. That thing was maybe not as long as a sandstorm, but definitely as chubby

No alaskan bull worm?

Could add the Exogorth from The Empire Strikes Back. That thing was massive.

Where Krayt dragon?

I’m curious as to the comparison of the No Man’s Sky sandworm.

It’s a BEEEEG boi.

I think the Saturn Sand Worm was a good change to the original flying clocks in an empty void idea.

Must be a height chart...?

No, is a small specimen. Only 125 meters long.
- Yeah but the chart might show how far above ground they go, which would make a lot more sense in that case. Because Sarlac is very low to the ground.
