Compositional Grid System

Standard Technical Poster (16:9 Aspect Ratio)

For 1920×1440px poster:

+------+----+----+----+----+----+----+----+----+------+
| Safe | 80px margin                          | Safe |
| Area +----------------------------------+  Area
|      |       Content Area (1760×1280px)  |  |
|      | Title: 100px height               |  |
|      | Device: 800px height (centered)   |  |
|      | Labels: 120px below device        |  |
|      | Annotations: Sides (±350px from center)
|      +----------------------------------+  |
+------+----+----+----+----+----+----+----+----+------+

Margin Standards

• Top/Bottom: 80-120px (breathing room)
• Left/Right: 80-100px (balanced gutters)
• Between sections: 40-60px (visual separation)

Exploded-View Spatial Relationships

Linear Offset Model

Layer 1 (Casing):        Y = 250px
Layer 2 (Interface):     Y = 340px (offset: +90px)
Layer 3 (Thermal):       Y = 430px (offset: +90px)
Layer 4 (PCB):           Y = 520px (offset: +90px)
Layer 5 (Battery):       Y = 610px (offset: +90px)

Consistency ensures viewers understand assembly progression.

Horizontal Alignment

All layers:

• Left edge: center_x - (width/2)
• Center: center_x
• Right edge: center_x + (width/2)

Maintains single axis of assembly (reduces cognitive load).

Visual Hierarchy with Typography

Text Sizing Strategy

Title ("NOVA"):          72-96pt   Bold     Primary element
Subtitle:                14-16pt   Regular  Supporting info
Component Labels:        16-18pt   Bold     Primary callouts
Annotation Text:         12-14pt   Regular  Secondary info
Footer/Attribution:      10-12pt   Regular  Least important

Spacing Between Components and Labels

Component Bottom → Label Top:  30-40px
Label Text → Next Component:  60-80px
Annotation Text ← Leader Line: 25-35px

Annotation Organization

Quadrant-Based Layout

         TOP AREA
           (Title)

LEFT       |     DEVICE CENTER     |      RIGHT
CALLOUTS   |    (Exploded View)    |    CALLOUTS

       BOTTOM AREA
    (Footer/Attribution)

Callout Placement Rules

1. Balance: Equal annotations on left/right (visual equilibrium)
2. Proximity: Place callout near its component reference
3. Avoid Overlap: Never place text over component diagrams
4. Visual Flow: Read top-to-bottom, left-to-right naturally

Leader Line Best Practices

• Angle: 45° or more from horizontal (clearer direction)
• Direction: Point outward from components (clarity)
• Terminal: Dot (4-6px) at component, arrow or nothing at label
• Simplicity: Direct lines, avoid bent/curved (technical aesthetic)

Color Distribution Pattern

Surface Treatment (Components)

• Base Color: Primary color (casing, thermal, PCB, battery)
• Accent Edge: Secondary or accent color (top/left edge)
• Highlight Detail: White or contrast color (internal features)
• Border: 1-2px subtle outline in same or darker variant

Annotation System

• Leader Line: Muted gray (visual glue, low weight)
• Callout Dot: Muted gray with border
• Text: Dark text on light background (standard contrast)

Component Sizing

Relative Proportions

For exploded-view devices, components typically decrease in size:

Casing:           400 × 180px  (100%)
Interface:        360 × 150px  (90%)
Thermal:          320 × 140px  (80%)
PCB:              280 × 130px  (70%)
Battery:          240 × 120px  (60%)

Creates natural visual taper and spatial progression.

Professional Finishing Touches

1. Alignment: Use grid helpers to ensure straight edges
2. Consistency: Match line weights and spacing precisely
3. Breathing Room: Generous margins around all content
4. Contrast: Sufficient color contrast for readability
5. Finish: Add subtle attribution/date footer for documentation
6. Polish: Review for visual balance before export

Layout QA Checklist

• All layers horizontally aligned to center axis
• Vertical spacing consistent between components
• Annotations balance left/right
• No text overlaps components
• Leader lines point clearly to components
• Color contrast meets WCAG AA (4.5:1 minimum)
• All text legible at printed sizes
• Margins provide breathing room
• Title area clearly distinguished
• Footer provides proper attribution
