How to Use Resume Lines: A Design Guide for Visual Impact

In the world of resume design, small visual elements can make a significant difference. Lines, dividers, and separators are among the simplest design tools available, yet they’re often overlooked or used poorly. When implemented thoughtfully, these elements create visual hierarchy, guide the reader’s eye, and give your resume a polished, professional appearance.

But there’s a catch: in our age of applicant tracking systems, even simple design choices come with considerations. Lines that look great to humans might confuse automated systems. Heavy graphic elements that seem impressive can make your resume feel cluttered rather than clean.

This comprehensive guide teaches you how to use lines effectively on your resume. From understanding their purpose to implementing them properly across different formats, you’ll learn to leverage this simple design element for maximum impact while avoiding common pitfalls.

Understanding the Purpose of Resume Lines

Before adding lines to your resume, understand what they accomplish and when they’re helpful.

Creating Visual Hierarchy

Lines help establish visual hierarchy—the organization of elements to show their relative importance. A line under your name sets it apart as the most important element. Lines between sections tell readers that one topic has ended and another begins.

Without visual hierarchy, resumes become walls of text where everything competes for attention. Properly placed lines guide readers through your document in the order you intend.

Separating Sections

The most common use of resume lines is separating major sections: contact information from professional summary, work experience from education, etc. These dividers create clear breaks that help readers navigate your resume quickly.

Section separation is particularly valuable because hiring managers often scan rather than read. Clean visual breaks help them find the information they’re looking for without reading everything sequentially.

Adding Visual Interest

Let’s be honest: resumes can be visually dull. While content matters most, a well-designed resume is more pleasant to read. Strategic lines add visual interest without overwhelming the document or distracting from your qualifications.

The goal isn’t to make your resume “pretty”—it’s to make it professional and polished in a way that reflects well on you as a candidate.

Guiding the Eye

Lines can direct attention to specific areas of your resume. A line under your name draws the eye there first. Lines that extend partially across the page can create interesting visual patterns that guide reading flow.

Understanding how eyes track across documents helps you use lines to control the reader’s journey through your content.

Types of Resume Lines

Different line styles serve different purposes. Understand your options before designing.

Horizontal Lines

The most common resume lines run horizontally across the page:

Full-Width Lines: Extend from margin to margin. Strong visual break, clearly separates sections. Can feel heavy if overused.

Partial Lines: Extend only partway across the page. Lighter feel, still provides separation. Often more visually interesting.

Underlines: Sit directly beneath text (usually headings). Emphasize specific elements without separating content.

Double Lines: Two parallel lines together. Stronger visual weight, often used for name or major section breaks.

Vertical Lines

Less common but useful in specific designs:

Column Dividers: Separate columns in multi-column layouts. Essential when using sidebar designs.

Accent Lines: Short vertical lines used as decorative elements or bullets.

Timeline Lines: In chronological layouts, vertical lines can connect career progression visually.

Decorative Lines

More stylized options for creative resumes:

Dashed or Dotted Lines: Lighter than solid lines, add texture without visual weight.

Gradient Lines: Fade from solid to transparent. Modern but may cause ATS issues.

Shaped Lines: Curved, angled, or otherwise non-straight. Only for creative fields.

Color Lines: Lines in colors other than black or gray. Can support personal branding but require restraint.

Where to Place Lines on Your Resume

Strategic placement maximizes impact. Here are the most effective locations:

Under Your Name

A line beneath your name visually sets it apart as the most important identifier on the page. This is perhaps the most common and universally appropriate use of resume lines.

Implementation:

• Place line immediately below your name
• Extend full width or partial width (often spanning just beneath the name itself)
• Use a slightly thicker weight than section dividers for emphasis

Between Major Sections

Lines between sections (Contact, Summary, Experience, Education, Skills) create clear organization:

Implementation:

• Place lines after each section ends, before the next begins
• Keep line weight consistent throughout the document
• Consider whether you need lines between ALL sections or just some

Under Section Headers

Underlines beneath section headers emphasize headings and create anchor points:

Implementation:

• Line extends from beginning of header text to end (not full page width)
• Creates a “title” effect that clearly marks new sections
• Can be combined with OR replace between-section lines (not both)

In Headers/Footers

Lines separating headers or footers from main content:

Implementation:

• Common in traditional business documents
• Creates formal, professional appearance
• Clearly delineates contact info or page numbers from content

Within Multi-Column Layouts

If using columns, vertical lines may separate them:

Implementation:

• Place centered between columns
• Extend full height of column content
• Keep weight light to avoid visual heaviness

Line Weight and Style Considerations

The thickness and style of your lines affect their visual impact.

Line Weight

Thin Lines (0.5-1pt): Subtle, lightweight appearance. Elegant but may be nearly invisible when printed or scanned.

Medium Lines (1-2pt): Good balance of visibility and subtlety. Most versatile choice.

Thick Lines (2-4pt): Strong visual presence. Use sparingly; can feel heavy.

Variable Weight: Thicker for major breaks (like under name), thinner for section dividers.

Color Choices

Black: Classic, always appropriate, highest contrast.

Gray: Softer than black, less formal, more modern feel.

Brand Colors: Can support personal branding but must be subtle and professional.

General Rule: Stick to black or gray for most resumes. Color lines only in creative fields or when they match a coherent design strategy.

Style Options

Solid: Standard choice, works everywhere.

Dashed: Lighter feel, adds texture. May not render well in all systems.

Dotted: Very light, decorative. Can appear informal.

Double: Stronger emphasis, formal appearance.

ATS Compatibility Concerns

Applicant tracking systems parse resumes automatically. Some design elements cause problems.

How Lines Can Cause ATS Issues

Text Recognition: Heavy lines near text can confuse optical character recognition.

Section Identification: Unusual line placement might interfere with section detection algorithms.

File Corruption: Complex graphic elements sometimes corrupt during file conversion.

Formatting Loss: Lines may disappear or move when ATS strips formatting.

ATS-Safe Line Practices

Use Simple Lines: Basic horizontal lines created through word processor tools (not inserted graphics) are safest.

Avoid Complex Graphics: Decorative lines, gradients, or shapes are more likely to cause issues.

Test Your Resume: Upload to a free ATS simulator to see how your resume parses.

Have a Plain Version: Keep an ATS-optimized version with minimal formatting for systems that struggle with design.

Place Lines Away from Text: Lines that overlap or are very close to text can interfere with parsing.

Creating Lines in Word Processors

How you create lines affects ATS compatibility:

Microsoft Word:

• Use border tools (Format > Borders and Shading) for simple lines
• Or type three hyphens (---) and press Enter for an automatic line
• Avoid inserting shapes or images for lines

Google Docs:

• Use horizontal line insertion (Insert > Horizontal line)
• Or use table borders with invisible cells
• Avoid drawings or inserted images

Design Software:

• If using InDesign, Illustrator, or similar, export carefully
• Test ATS compatibility before sending
• Consider having a separate Word version for ATS-heavy applications

Design Principles for Resume Lines

Follow these principles for effective line usage.

Consistency Is Key

Whatever line style you choose, apply it consistently:

• Same weight throughout (or intentional variation for hierarchy)
• Same style (all solid, all dashed, etc.)
• Same spacing before and after lines
• Same length pattern (all full-width or all partial)

Inconsistency looks careless. Consistency looks intentional and professional.

Less Is Often More

Resist the urge to add lines everywhere:

• One line per section break is plenty
• You don’t need lines AND extra white space
• Dense line usage feels cluttered
• Minimal lines feel clean and modern

If your resume has more lines than sections, you probably have too many lines.

White Space Works With Lines

Lines and white space serve similar purposes. Use them together thoughtfully:

• Lines can replace white space as separators
• Or white space can soften line breaks
• Too much of both creates excessive separation
• Find balance between the two

Lines Should Support, Not Dominate

Lines are supporting elements—they should enhance, not overshadow your content:

• If you notice the lines more than the content, they’re too prominent
• Lines should guide attention to content, not compete with it
• When in doubt, make lines lighter, not heavier

Step-by-Step: Adding Lines to Your Resume

Here’s a practical guide to implementing lines across common tools:

In Microsoft Word

Adding a Line Under Your Name:

1. Position cursor at end of your name
2. Press Enter to create new line
3. Go to Home tab > Borders dropdown
4. Select “Horizontal Line” or “Bottom Border”
5. Adjust formatting as needed

Adding Section Dividers:

1. Position cursor between sections
2. Go to Format > Borders and Shading
3. Choose “Horizontal Line”
4. Or select the section header and add bottom border

Adjusting Line Weight and Style:

1. Click on the line to select it
2. Right-click and choose “Format Horizontal Line”
3. Adjust width, height, color, and alignment

In Google Docs

Adding Horizontal Lines:

1. Position cursor where you want the line
2. Click Insert > Horizontal line
3. The line will be basic black; limited customization available

Alternative Using Tables:

1. Insert a 1x1 table
2. Remove top, left, and right borders
3. Keep bottom border as your line
4. Adjust border weight in table properties

Using Paragraph Borders:

1. Select your section heading
2. Click Format > Paragraph styles > Borders and shading
3. Add bottom border only
4. Adjust weight and color

In Design Software

Adobe InDesign or Illustrator:

1. Use line tool to draw lines
2. Adjust stroke weight, color, and style in properties
3. Ensure lines are vector, not raster
4. Export to PDF with fonts embedded

Canva:

1. Use line elements from sidebar
2. Adjust weight, color, and style
3. Position carefully
4. Download as PDF for best results

Important: Design software creates visually impressive resumes but may cause ATS issues. Always test compatibility.

Examples of Effective Line Usage

Let’s examine how lines work in different resume styles:

Classic/Traditional

Line Usage:

• Single line under name
• Lines between each major section
• Conservative weight (1pt black)
• Full-width lines

Effect: Professional, formal, appropriate for traditional industries.

Modern/Minimalist

Line Usage:

• Thin line under name only
• White space between sections (no lines)
• Or very subtle gray lines
• Partial width for lighter feel

Effect: Clean, contemporary, appropriate for tech and creative-adjacent fields.

Creative/Design-Forward

Line Usage:

• Lines as design elements (varying weights, colors)
• Geometric patterns using lines
• Accent lines highlighting key information
• Intentional asymmetry

Effect: Visually distinctive, appropriate for creative fields only.

Two-Column Layout

Line Usage:

• Vertical line separating columns
• Horizontal lines within sections
• Careful balance between vertical and horizontal elements

Effect: Organized and efficient use of space, appropriate for any field when done cleanly.

Common Mistakes to Avoid

Learn from others’ errors:

Too Many Lines

Problem: Lines between every element create visual noise. Solution: Use lines only for major section breaks. Let white space handle smaller separations.

Inconsistent Line Usage

Problem: Different weights, styles, or placements throughout. Solution: Decide on one approach and apply it consistently.

Lines That Overpower Content

Problem: Heavy, colorful, or elaborate lines distract from qualifications. Solution: Keep lines subtle. They should guide attention, not demand it.

Ignoring ATS Compatibility

Problem: Beautiful lines that prevent your resume from being parsed. Solution: Test in ATS simulators; maintain a plain-text version for problematic systems.

Lines Without Purpose

Problem: Decorative lines that don’t serve visual hierarchy. Solution: Every line should separate sections, emphasize elements, or guide reading flow. If it doesn’t do any of those, remove it.

Poor Spacing Around Lines

Problem: Lines crammed against text or too far from sections they divide. Solution: Maintain consistent spacing above and below lines (typically 6-12pt).

Industry Considerations

Different industries have different design tolerance:

Conservative Industries (Law, Finance, Government)

Recommendation: Minimal, traditional line usage

• Black lines only
• Standard horizontal dividers
• No decorative elements
• Clean, formal appearance

Corporate/Business

Recommendation: Professional with slight modern touches

• Black or dark gray lines
• Clean horizontal dividers
• Possibly subtle accent line under name
• Polished but not flashy

Technology

Recommendation: Modern, clean design acceptable

• Subtle lines or no lines (white space works)
• Gray or colored accent acceptable if subtle
• Two-column layouts with dividers work well
• Contemporary but professional

Creative Industries

Recommendation: Design can be part of your pitch

• Lines as design elements
• Color and weight variation acceptable
• Creative layouts welcomed
• Just ensure it’s still readable and functional

Academia

Recommendation: Simple and traditional

• Basic section dividers
• Conservative formatting
• Focus on content, not design
• CVs have different conventions than resumes

When to Skip Lines Entirely

Sometimes the best line choice is no lines at all:

White Space-Centric Designs

Clean, modern resumes often use white space instead of lines for separation. This approach can feel more contemporary and less visually heavy.

Very Dense Content

If you have extensive content that needs space, removing lines creates more room for what matters.

ATS-Heavy Job Applications

When applying to systems known to have parsing issues, simpler formatting is safer.

When Lines Don’t Add Value

If your resume reads well without lines, you may not need them. Lines are tools, not requirements.

Conclusion: Lines as Intentional Design Choices

Resume lines are small elements with meaningful impact. When used thoughtfully, they create visual hierarchy, guide readers through your content, and contribute to a polished professional presentation. When used poorly, they clutter your resume or cause technical problems.

The key principles to remember:

Purpose: Every line should serve a function—separating sections, emphasizing elements, or guiding attention. Decorative lines without purpose add clutter.

Consistency: Whatever approach you choose, apply it uniformly throughout your resume. Consistency signals intentionality and professionalism.

Restraint: Less is typically more with resume lines. When in doubt, use fewer lines with less visual weight.

Compatibility: Design choices must work with applicant tracking systems. Test your resume and maintain a simpler version for problematic applications.

Your resume’s visual design reflects your professionalism before anyone reads a word. Lines are one tool among many for creating that positive first impression. Use them wisely, and they’ll enhance your presentation. Use them thoughtlessly, and they may undermine it.

The best resume design is one you don’t notice—where everything works together seamlessly to showcase your qualifications. That’s the goal for your use of lines: invisible in their excellence, noticeable only in their absence.

---

Resume design involves countless small decisions that collectively create an impression. Lines are just one element among many, but attention to details like this distinguishes polished, professional resumes from amateur ones. Take time to consider every design choice intentionally, and your resume will reflect the same care you’d bring to your work.
