Compare 20mm and 40mm x 20mm dual use bases from Wargames Atlantic. Learn which base size fits your miniatures and gaming style.
Quick Answer
Choose 20mm dual use bases for single infantry figures with small footprints, and 40mm x 20mm dual use bases for larger models, cavalry, or units needing a wider stance. Both offer a recessed side for puddle bases and a flat side for direct gluing.
Why Base Size Matters
Base size affects gameplay, storage, and visual consistency. Smaller bases fit more models per area, while larger bases provide stability for top-heavy figures and make unit spacing easier to manage.
Both dual use bases solve the common problem of figures with integral puddle bases sitting unevenly. The recessed side keeps feet flush with the base edge, while the flat side suits figures with flat feet.
Trade-offs Between 20mm and 40mm x 20mm
The 20mm base is compact and ideal for rank-and-file infantry. It keeps units tight and is easier to fit on crowded tabletops. However, it offers less surface area for basing details or larger models.
The 40mm x 20mm base gives more room for scenic basing and better balance for larger figures. The extra length can help cavalry or elongated models, but it takes up more space and may require adjusting unit formations.
Decision Guide
- Footprint and Stability: 20mm bases are square and compact, ideal for single infantry. 40mm x 20mm bases are rectangular, offering more surface area and a lower center of gravity for taller models.
- Puddle Base Compatibility: Both have a 1mm recess to accommodate integral puddle bases. Use the recessed side for those figures; use the flat side for figures with flat feet. Check your miniatures for puddle bases before choosing which side to use.
- Gameplay and Aesthetics: Smaller bases allow tighter unit formations; larger bases make spacing easier and provide room for basing details. Choose based on your game's movement rules and your preferred tabletop look. Consider your game system's base size requirements before purchasing.
