So, according to Ianmiddy's graph, an ISD would be about 30" long? (Clearly, we need to use Imperial measure here.)

That wouldn't be too bad at all on a table top. . .

If you feed Refugeanoth's Debilitator Interdictor " Omen " into the formula, it comes out as about 360m at a scale of 1/680...a Victory 1 SD at 900m gives 1/1227 and just under 26"...I have to admit that I think it maybe works up to the Interdictors size, but anything over that really depends on how familiar you are with the ships being played side-by-side - maybe an SD is just too well known as massive?

To some extent it also depends on how many of these giant ships you have side-by-side on the table. As @Refugeanoth 's Omen shows, a single giant ship next to the rest of the X-Wing models looks massively impressive and dominates the table. So if I had a 26" long ISD model on the table and no other giant ships, I'd be perfectly happy calling it an Imperial Star Destroyer. Now if you wanted to build a fleet of giant ships and have Interdictors and Venators and Victory/Imperial class Star Destroyers flying along side one another, then scaling becomes far more important and begins to get impractacle.

Yeah, probably. But an Arquitens (which has been featured quite heavily in Rebels) would probably look great.

I suppose another cool idea with be a "2D approaching 3D" ship fragment that sat alongside the play area. . .the only thing the players would be able to destroy would be things like gun emplacements and hangar bays, with some rule for the "mega-critical hit" that takes it out.

At 1 yard long, a scaled ISD would still take up 1/2 the play area in 6x3 epic. It would still certainly have gravitas. But I agree, any more than 1 outsized ship would start to erode the suspension of disbelief.

An Arquitens might just be a playable ship. though it would be very very large. You'd probably be talking a model that is roughly 2.5-3' long. You'd probably need 8 or so large bases to make up it's actual base.

Extremely Large ships could be an interesting addition to the game, but you'd have to be playing games with at least six to nine 3x3 mats at that point. Those would take all weekend to resolve.

Sounds Good, Lets do it. Make it a 3 section ship (Forward body and hanger bay, Bridge, Engines). So 3 damage decks and here is an idea for the base or more like 4 bases arranged into a tripod of sorts.

Just out of interest, MacrossVF1's Arquitens fits almost exactly onto the graph, at 325m / 1:642 / 50.63cm [19.9"]

...but, please note that I've found a wide range of lengths, from below 200m to the 325m above, which could drop it down as low as just over 15"...but the upper end seems more realistic to me based upon the appearances in Rebels - not having seen season 3, are there any instances where one appears in frame with a Nebulon ?

Spoiler alert boyos, my next big project is bringing one of Randy Coopers star destroyers to life in xwing! A little over 3 foot long by 2 feet wide and exactly double the size of the Omen! I've tested movement of something like that on a 6x3 board and with the base being 2x1 beneath it and the ship being elevated high enough off the table and using my 3 dial movement rules for the Omen it's actually usable!

Call it 33" and change... on a table that's 36" wide and 72" long.... not sure how wide the actual "base" of the model would be (as in the width of the rear of the ship) but I'm guessing somewhere are 10" or so (maybe 12") as for the size of the movement bases and practicality of a ship that big. Epic would need a bigger boat I mean table. I used to have the ability to play on the floor where I lived and the largest area we played 40k on back then was 14 feet on a side (we could go a lot bigger but it got quite difficult actually moving the models and measuring range). Maybe an 8 or 9 foot table might work but it gets harder and harder to move things.

A Sentinel-class shuttle slides between the mandibles for docking in one episode. . .

In my experience 6x6 is about as big as you can get without making player reach a big issue. About 15 years ago a made a fold-away 6x6 plywood board that I painted green for fantasy war games. It has been co-opted for 600-point and 1,000-point XWM games using 4 play mats.

OTOH, despite what Refugeanoth has done, I would have ships that size move very little during play. That would fit with the movies in terms of fighters screaming around the capital ships while they are rather "stationary."

The main problem with ISDs is their armament. The card Single Turbolaser represents light Turbolasers. The XX-9 Turbolasers are much more powerfull. And an ISD has 60 of them. Adding the very strong shields (which starfighters can only pebetrate when using volleys of 24 or more Proton Torpedoes concentrated on a very small area) and armour they have to be around 2000 plus points. And thats not counting the heavy barbette Turbolasers and tractor beams.

An ISD is equal to 10 Nebulon B or 20-30 CR90.

It's not the scale for the A, X, B, Y wings (or any small or large base ships) that is varying, it's what folks accept as the length of the ships that is varying.

You're right and I don't know how many more times this has to be said...

Per the canon states listed on StarWars.com the ships in X-Wing TMG are all the correct size at 1/270 scale. The fact that some people think the Y-Wing should be bigger than what's listed as canon or the A-Wing smaller doesn't change what the canon size is, and FFG has to use the canon sizes.

If you want debate what the canon size is, go ahead, I won't get involved in that again, because what someone thinks the canon size should be, doesn't really matter in regards to what sizes FFG had to use.
