Movement Tray Calculator — Regiment Formation
Calculate movement tray dimensions for your regiment size and base shape.
How We Calculate This
Calculates tray dimensions from base size, grid arrangement and spacing.
Formula
- Tray width = Columns x (Base + Spacing) + (2 x Border) - Spacing
- Tray depth = Rows x (Base + Spacing) + (2 x Border) - Spacing
- Total models = Rows x Columns
Frequently Asked Questions
MDF (laser-cut) is the most popular and cost-effective. Suppliers like Warbases and Sarissa Precision offer custom-sized trays. Magnetic sheet trays with magnetised bases are excellent for transport. 3D printed trays are another option.
For round bases, 1-2mm spacing between bases allows easy removal of individual models. For ranked square bases, 0mm spacing (bases touching) is standard. Some players prefer 1mm for easier handling.
A 2-3mm border is sufficient for strength without adding too much to the footprint. Wider borders (5mm) make the tray sturdier and easier to pick up. Some players texture the border to match their army basing scheme.
Not usually. Movement trays are mainly for rank-and-flank games (Kings of War, The Old World) where units move as blocks. In skirmish games (40K, AoS), models move individually. However, trays speed up movement even in skirmish games with large units.
