Are you asking is the swamp fiend model larger than the goblin myrimdon. Yes it is. Or should be/would be. It really depends on the spider-model you get. The goblins you can use are blowpipers and/or spearman. I used blowpipers and a grendel spider but there is another spider on this forum that is great (and is like 60 bucks). That's probably how I'd do it. Ultimately think no higher than 3 and 1/2 to 4 and 1/2 inches max in hieght. I think in my sizing of the game I put Size 2 at 1 and 1/2 inches, and 2 and 1/2 inches as Size 3 (that means a model can vary from 2 and 1/2 to 3 and 1/2 inches and still be considered Size 3. I would have to look at my rules to make sure. I used the same approach you see in Infinity which uses 7 sizes and has a 'minimal profile'. I just reduced it to height in inches yet you would end up with a little template if you really wanted it used to measure Cover for a model behind something. That is more advanced that Chronopia. In Chronopia just go by the model and if you see 50% of WYSIWYG. Also we play with 'no wings or weapons' so wings on a dragon don't count nor do Lances and other obvious weapons sticking out. We assume the model represents a dynamic pose and motion, not a static model.
