Buying Guide
When selecting a router letter template kit, consider the following factors to ensure the best value and performance for your projects:
- Interlocking design vs. flat templates: Interlock systems aid precise alignment and kerning, but may have a larger footprint. Choose based on sign size and routing table space.
- Letter height and set completeness: Taller templates (e.g., 3-3/8” or 4”) are better for outdoor visibility, while smaller heights suit indoor signs and plaques. Ensure the set includes all necessary characters for your typical projects.
- Kerning and spacing: Kerning spacers help achieve even letter spacing. A kit with adjustable spacing is beneficial for natural typography across varied word lengths.
- Compatibility with router bits: Verify the required bit sizes (e.g., 3/8″, 5/8″) are compatible with your current router and bits. Some kits include bushings or require separate purchases.
- Material durability: Durable polymer templates resist wear and tear from repeated routing. Metal or reinforced templates may provide longer life in heavy-use environments.
- Ease of use: Self-spacing features and clearly labeled letters reduce set-up time and mistakes, particularly for beginners.
- Maintenance and replacement parts: Check whether spare letters, spacers, or bushings are readily available through the same brand or retailer.
- Bottom-line workflow: Consider how the template kit integrates with your workflow—whether you route on a plunge router, with a perforated base, or require additional guides for multi-line text.
- Font choice and aesthetics: Comic Sans provides a casual look; state park and other classic fonts offer a more traditional appearance. Match font to project purpose and audience.
