Verify Grid Alignment

How to check that your map’s grid matches Mimir’s grid overlay, and what to do if it doesn’t.

Goal

Ensure that tokens snap to the correct grid squares on your map.

Steps

For UVTT Files

1. Upload your UVTT file (see Upload a Map)
2. Open Token Setup by clicking the map card
3. Verify: The grid overlay should align with the map’s drawn grid lines
4. Place a test token — it should snap to the center of a grid square

UVTT files embed grid data (cell size, offset, dimensions), so alignment is automatic. If the grid looks correct, you’re done.

For Image Files

1. Upload your image file
2. Open Token Setup by clicking the map card
3. Check alignment: Mimir defaults to 70 pixels per grid square, starting from the top-left corner
4. If the overlay grid lines align with the map’s drawn grid, you’re ready to place tokens

If the Grid Doesn’t Align (Image Files)

If your image uses a non-standard grid size (e.g., 100px squares), the overlay won’t match the map artwork. Options:

1. Obtain the UVTT version of the map if available — this is the best fix
2. Use the map as a visual backdrop and position tokens by eye rather than relying on snap-to-grid

How Token Snapping Works

• Tokens snap to grid centers when placed
• Token size respects the grid — a Large creature occupies a 2×2 area, Huge occupies 3×3
• The grid overlay in Token Setup shows exactly where tokens will land
