Basics of Card Stock, Weight, and Core

Guide to Manufacturing

By Tom Law and Alex Lim丨July 16, 2024
As a new board game publisher, selecting the right paper weight and card stock for your game components is crucial. So here’s a quick guide to help you make informed choices that enhance durability and quality.
UNDERSTANDING GSM
GSM (grams per square meter): Measures paper thickness and weight.
Higher GSM: Thicker, heavier paper, offering better durability and quality.
WHY GSM MATTERS
· Lighter weights (70gsm-140gsm): Ideal for rule books, instruction sheets, and score pads.
· Medium weights (150gsm-200gsm): Perfect for player mats, reference cards, and small tokens.
· Heavier weights (200gsm-350gsm): Best for game boards, premium cards, and other printed components.

Choosing the right GSM ensures your components are durable and provide a high-quality feel, enhancing the player experience.
CARD STOCK SELECTION

When designing game cards, the material is key to durability and gameplay experience. Here’s a breakdown of card materials:
· Art Paper: Thick and stiff, great for prototypes but not for frequent shuffling.
· Card Stock: Durable, with a core, and excellent for shuffling and regular use.
· Plastic: Highest durability, less common in board games.
 
BENEFITS OF CARD STOCK
Card stock, made by gluing two layers of paper with a core (usually graphite laminate), is preferred for game cards due to its:
· Snap
· Resilience to bending
· Improved shuffle
· Overall durability
TYPES OF CORE
Different cores affect card quality and opacity. Common options include:
· Gray Core: Basic option.
· White/Ivory Core: Intermediate option.
· Blue Core: Higher quality, often the baseline for manufacturers.
· Black Core: Most premium, completely opaque, ideal for preventing transparency issues.

If curious, you can tear a card from any card game to see what type of core they’re using.
TIPS FOR NEW PUBLISHERS
· Prototyping: Use art paper to save costs.
· Production: Opt for card stock with a core for final products.
· Opacity: Choose black core if transparency is a concern in your game.
In conclusion, selecting the right card weight and core ensures your game cards are durable and provide an excellent player experience, leaving a lasting impression!
