Card size should be chosen based on use, not aesthetics.

Ask yourself:

• Will the card be read up close or at a distance?

• Is it held in one hand, both hands, or placed on a table?

• Is portability important, or visibility?

Smaller cards:

• Encourage brevity

• Are easier to shuffle and hold

• Suit fast gameplay or personal use

Larger cards:

• Support longer text and diagrams

• Improve group readability

• Work better for facilitation and teaching

Choosing a size that conflicts with how the card is used leads to frustration and redesigns.

How cards are physically handled should shape the entire design.

Consider:

• Shuffled frequently → durable stock, two-way backs, strong indices

• Held in hand → comfortable size, clear corners, readable at angles

• Laid out on tables → strong hierarchy, clear orientation

• Displayed or presented → large formats, minimal text, high contrast

Designing for the wrong handling method often results in cards that technically print well but fail in real use.

Readable text is determined by:

• Card size

• Viewing distance

• Lighting conditions

• Time spent reading

Guidelines:

• If it takes effort to read, there is too much text

• One idea per card improves clarity

• White space improves comprehension

Cards are not pages. Dense text belongs in a booklet, not on a card.

Card backs affect both usability and fairness.

Two-way (rotationally symmetric) backs are best when:

• Cards are shuffled and dealt

• Orientation should not be revealed

• Gameplay fairness matters

One-way backs are suitable when:

• Cards are read intentionally

• Orientation supports meaning or flow

• Cards are drawn, not shuffled

Choosing the wrong back orientation can unintentionally reveal information or confuse users.

Design decisions should be based on the end user, not the creator.

Ask:

• Is the user a player, student, coach, facilitator, or client?

• Will they hold the card for seconds or minutes?

• Is the experience fast-paced or reflective?

Short interactions favour:

• Bold visuals

• Minimal text

• Fast recognition

Longer interactions require:

• Comfortable handling

• Calm layouts

• Readable typography

Designing without a clear user in mind leads to mismatched expectations.
