Template Design Patterns — Advanced

Why Patterns Matter

As your template library grows, consistent design patterns help your team build faster, maintain templates easily, and ensure a professional look across all documents.

Header–Body–Footer Pattern

The most common document layout divides each page into three zones:

Header — Company logo, document title, date. Consistent across pages.
Body — Main content area with dynamic data
Footer — Page numbers, legal text, contact info

Spacing

Leave consistent margins between zones. A common setup is a 60px header, body starting at 80px, and footer at the bottom 40px of the page.

Grid-Based Layout

Align elements to an invisible grid for a clean, organized look:

Define a base unit (e.g., 8px or 10px)
Position all elements on multiples of the base unit
Use the grid & rulers feature as a visual guide
Keep gutters (spacing between columns) consistent

Two-Column Pattern

Perfect for invoices, receipts, and business letters:

Left column — Sender details, labels
Right column — Recipient details, values
Use equal widths or a 40/60 split
Align elements to the same vertical baseline

Data-Driven Pattern

Design templates that adapt to varying data lengths:

Use field elements for all variable content
Test with minimal data and maximum data
Add conditional elements for optional sections
Position elements relative to data flow, not absolute positions

Consistent Branding Pattern

Define brand colors and use them consistently across templates
Use the same font family across all documents
Place logos in the same position on every template
Define a set of reusable style presets for headings, body text, and labels

Naming Conventions

Use clear, consistent naming for templates and data fields:

Type	Convention	Example
Templates	document-type-variant	invoice-standard, invoice-detailed
Field keys	camelCase	customerName, invoiceDate
Table columns	camelCase	itemDescription, unitPrice

Modular Design

Break complex templates into logical modules:

Header module — Reuse the same header section across templates
Address block — Standard sender/recipient layout
Line items — Table with consistent column widths
Totals block — Subtotal, tax, total in the same position
Footer module — Legal text, page numbers, branding

Reusable Layouts

See Reusable Layouts for techniques to share common sections across templates.

Template Testing Checklist

Test with minimum data (all optional fields empty)
Test with maximum data (longest expected values)
Test with special characters and accented text
Test multi-page overflow behavior
Verify alignment in the generated PDF, not just the editor
Check print output at actual size
