Learn how to define a simple, repeatable illustration style so every graphic on your website feels on-brand, consistent, and professional.
Why Your Website Needs an Illustration Guide
Illustrations can make your website feel human, memorable, and unique. Without clear rules, though, graphics quickly become inconsistent, off-brand, and confusing for visitors.
A practical brand illustration guide gives your team simple, repeatable rules so every new graphic looks like it belongs to the same visual family.
Before You Start: What You Need
- Your brand color palette (primary and secondary colors)
- Your typography choices (heading and body fonts)
- A few example illustrations you already like (even if they are rough)
- Access to your design tool of choice (Figma, Adobe, Canva, or similar)
Step 1: Define the Purpose of Your Illustrations
Start by deciding what illustrations should actually do on your website. This keeps your guide focused and prevents random decorative graphics.
Questions to Answer
- Will illustrations explain complex services or processes?
- Will they represent people, products, or abstract concepts?
- Will they appear mostly on hero sections, feature blocks, or blog posts?
Write a short purpose statement, for example: “Our illustrations help explain our services in a friendly, simple way and appear on hero sections, feature highlights, and key blog posts.”
Step 2: Choose an Illustration Style and Stick to It
Pick one primary style and commit to it. Mixing too many styles is the fastest way to lose brand consistency.
Common Illustration Style Options
- Flat vector: Clean shapes, minimal shading, simple outlines.
- Outlined: Line-based drawings with limited fills and color accents.
- Geometric: Built from circles, rectangles, and triangles with clear grids.
- Abstract: Shapes and patterns that suggest ideas rather than literal scenes.
Document Your Style Rules
Create a short section in your guide that answers:
- Are illustrations flat or shaded?
- Are outlines used? If yes, how thick?
- Are shapes rounded or sharp?
- Are characters realistic, simplified, or abstract?
Write these as simple bullet rules your team can follow.
Step 3: Set Clear Color Rules for Illustrations
Illustration color should support your existing brand palette, not compete with it.
Color Guidelines to Define
- Primary illustration colors: 2–4 colors from your main palette used most often.
- Accent colors: 1–2 colors used sparingly for emphasis.
- Neutrals: Grays, off-whites, or muted tones for backgrounds and details.
- Restrictions: Colors that should never be used in illustrations.
Include small color swatches with hex codes and short notes like “Use this blue for main shapes” or “Use this yellow only for highlights and buttons.”
Step 4: Define Line, Shape, and Detail Levels
Consistency in line weight and detail level makes separate illustrations feel like a unified set.
Line and Shape Rules
- Specify one or two line weights (for example: 2 px for main outlines, 1 px for details).
- Decide whether corners are rounded or sharp.
- Limit the number of small details to keep graphics clean and readable.
Detail Level Examples
- Faces: simple dots and lines, no complex shading.
- Backgrounds: minimal, only key shapes that support the main idea.
- Textures: either none, or a single simple pattern used consistently.
Step 5: Create a Simple Character and Object System
If your brand uses people or recurring objects, define how they should look so they are recognizable across the site.
Character Guidelines
- Body proportions (realistic, simplified, or exaggerated).
- Facial features (minimal, expressive, or abstract).
- Clothing style (formal, casual, or neutral).
- Representation (inclusive skin tones, body types, and accessibility cues).
Object Guidelines
- How you represent devices, tools, or products.
- How simplified each object should be.
- Whether you use icons or full scenes for certain concepts.
Add 2–3 example characters and objects to your guide with short notes like “Use this character as the base for all team illustrations.”
Step 6: Match Illustration Use to Website Layouts
Next, decide where illustrations appear and how they interact with your layouts in WordPress or Elementor.
Placement Rules
- Hero sections: one main illustration on the right, text on the left.
- Feature sections: small spot illustrations above each feature title.
- Blog posts: one illustration per article at the top, optional small graphics within the content.
Size and Spacing Guidelines
- Minimum width for hero illustrations (for example: at least half the content width).
- Consistent padding around illustrations so they do not feel cramped.
- Rules for alignment: left, right, or centered depending on section type.
Step 7: Prepare Web-Ready Illustration Files
To keep your site fast and sharp, define how illustration files should be exported and uploaded.
Export Settings
- Use vector formats (such as SVG) when possible for simple, flat illustrations.
- Use high-quality compressed PNG or JPG for complex scenes.
- Set a maximum width for large hero graphics to avoid oversized files.
Naming and Organization
- Use clear file names like service-illustration-consulting instead of generic names.
- Organize illustrations into folders by page or section (hero, features, blog, etc.).
Step 8: Add Your Guide to WordPress for Easy Access
Storing your illustration guide inside WordPress makes it easy for your team to find and follow.
How to Add Your Guide as a Page
- Go to Dashboard ? Pages ? Add New.
- Title the page something like “Brand Illustration Guide.”
- Add sections that match the steps above: Purpose, Style, Color, Line and Detail, Characters, Placement, Export Rules.
- Insert example images directly into the page using the image block or Elementor image widget.
- Set the page visibility to Private if it is only for internal use.
- Click Publish.
What You Should See
- A new “Brand Illustration Guide” page listed under Dashboard ? Pages ? All Pages.
- Clear headings for each section of your guide.
- Example illustrations displayed with notes and rules beneath them.
Step 9: Create a Simple Checklist for New Illustrations
End your guide with a quick checklist that designers, marketers, or freelancers can use before uploading new graphics.
Sample Illustration Checklist
- Does this illustration match our chosen style (flat, outlined, geometric, or abstract)?
- Are only approved brand colors used?
- Are line weights and details consistent with the guide?
- Does it use our standard character and object rules?
- Is the file exported in the correct format and size?
- Is the file named clearly and stored in the right folder?
Maintaining and Updating Your Illustration Guide
Your illustration system should evolve slowly, not change completely every few months.
- Review the guide every 6–12 months.
- Add strong new examples that match the rules.
- Note any exceptions and explain why they were allowed.
- Share updates with your team whenever rules change.
