How to Add a Live Font Picker and Character Limit for Engraving on Shopify

Personalized jewelry, leather wallets, wooden watches, and engraved gifts are among the highest-margin categories on Shopify. However, offering custom text engraving without clear constraints often leads to fulfillment nightmares:

• Customers submit essays that exceed the physical engraving area on a ring or watch caseback.
• Customers use unreadable emojis or symbols that your laser engraving software cannot render.
• Customers are unsure how their name will look in Script vs. Classic Roman fonts.

In this tutorial, you will learn how to set up custom font pickers, character limits, and real-time text validation using GP Product Options.

3 Essential Elements of a Great Engraving Experience

1. Hard Character Counter Limit

Set a strict maximum length (e.g., 12 characters for a ring inside band, or 25 characters for a leather wallet). The input should prevent typing beyond the limit and show a live countdown (e.g., 8 / 12 characters remaining).

2. Visual Font Picker with Swatches

Instead of standard dropdown text, display actual visual font cards showing real font typography:

• Classic Serif (Cinzel / Times)
• Modern Sans (Montserrat / Inter)
• Romantic Cursive (Great Vibes / Dancing Script)
• Gothic / Monogram Initials

3. Case Format Enforcement

Allow merchants to restrict input formatting:

• ALL CAPS ONLY (Ideal for geometric monograms or industrial stamping).
• Title Case (First letter capitalized).
• Alphanumeric Only (Prevents special emojis from crashing laser cutting software).
