How do you organize your dungeon tiles?

Dominic Matte

I'm slowly building a collection of maps and dungeon tiles for my D&D games. I know how I'm going to organize my poster maps because of this excellent article from TheSheDM, but I'm not too sure what to do with my tiles.

Among other things, I have the City, Dungeon, and Wilderness master set boxes. I'm thinking that I should divide my tiles up to fit those themes and put them in ziplock bags in the relevant box. For example, my Dark Sun tiles would go in their own bag in the Wilderness box, and the Underdark tiles would fit in the Dungeon box.

But this solution seems a little lacking given the sheer variety in each tile set. It did occur to me to keep each tile sheet in a plastic protector like in the above solution for poster maps. That would allow me to see both sides of each tile easily, but it comes with the functional downside of having to put the tiles back into the sheet every time I use some, and it won't stop them from falling out of the slots and clumping at the bottom during transport.

Should I have a bag for major battlefield landmarks, like the Wilderness set's cabin, ruined tower, and giant skeleton? 

Should I have subcategories for the size of tiles, even though similarly-sized tiles don't have much in common?

Should I categorize tiles by content, like pits or ruins? That ignores the back side of the tile.

What are your dungeon tile organization solutions? I'd love to hear about them in the comments, and feature my favourites in a future article.
