What Size Magnet Do I Need?
A MiniWarGaming Magnet Guide

Before you use this guide, it would help to understand the basics of choosing sizes.

In essence, it is pretty easy to figure out what size you need. All you have to do is measure the space where the magnet will go, then simply choose the largest magnet that will fit in that slot.

Flames of War


Any Unit1/16" x 1/32"
1/8" x 1/16"
Almost everything will use 1/16" magnets due to the scale. 1/8" will only be useful in spots that they can fit in.

Warhammer 40k

Any Non-Walker Vehicle1/16" x 1/32"
1/8" x 1/16"
3/16" x 1/16"
1/4" x 1/16"
Vehicles are big enough that they can use almost any size magnet, so the question is more what kind of weight it needs to hold.

If you are magnetizing something on the top, a 1/8" magnet should be enough.

If you are magnetizing something on the side, a 3/16" or 1/4" might be more appropriate, depending on how heavy the object is.

1/16" are only useful for small wargear options, where no other magnets will fit.

Chaos Space Marines

Daemon Prince1/8" x 1/16"
3/16" x 1/16"
As with other monstrous creatures, 1/8" will work, but 3/16" are much stronger and will fit.

Space Marines

Any Regular Troop Size Model1/16" x 1/32"This applies to any Space Marine Troop size model.

Terminators1/8" x 1/16"No notes

Boyz and Nobz1/16" x 1/32"No notes
Stompa1/8" x 1/16"
3/16" x 1/16"
1/4" x 1/16"
Again, the size depends on the weight of what you are holding up. The bigger arms will most likely need 1/4".

Any Vehicle1/8" x 1/16"
3/16" x 1/16"

XV8 Battlesuits1/8" x 1/16"No notes

Either size will work, although 3/16" will be more forgiving.
Gaunts1/16" x 1/32"No notes
Genestealers1/16" x 1/32"No notes
Hive Tyrant1/8" x 1/16"
3/16" x 1/16"
Plastic limbs can use 1/8" magnets, but you'll need 3/16" for the metal limbs.
Ripper Swarm1/8" x 1/16"No notes
Warrior1/8" x 1/16"
1/16" x 1/32"
Use 1/8" magnets on the limb joints, and 1/16" on the limbs themselves.

Warhammer Fantasy


20mm Base Units1/16" x 1/32"No notes
25mm Base Units1/16" x 1/32"No notes
40mm Base Units (Monstrous Infantry)1/16" x 1/32"
1/8" x 1/16"
You'll want 1/8" for metal models, but sometimes only 1/16" will fit.
Movement Trays1/8" x 1/16"You'll need to attach a piece of metal to the bottom of the movement tray. Use a small amount of green stuff to attach the magnets on the bottom of each base.


Any Metal Warjack3/16" x 1/16"If you aren't sure if a Warjack is plastic or metal, then assume it is metal.
Any Plastic Warjack1/16" x 1/32"
1/8" x 1/16"
If you aren't sure if a Warjack is plastic or metal, then assume it is metal.

1/16" for the faces, 1/8" for the arms.
