McKinsey PPT Design Framework

Overview

This skill encodes the complete design specification for professional business presentations — a consultant-grade PowerPoint framework based on McKinsey design principles. It includes:

  • 36 layout patterns across 7 categories (structure, data, framework, comparison, narrative, timeline, team)
  • Color system and strict typography hierarchy
  • Python-pptx code patterns ready to copy and customize
  • Three-layer defense against file corruption (zero p:style leaks)
  • Chinese + English font handling (KaiTi / Georgia / Arial)

All specifications have been refined through iterative user feedback to ensure visual consistency and professional polish.

When to Use This Skill

Use this skill when users ask to:

  1. Create presentations — pitch decks, strategy presentations, quarterly reviews, board meeting slides, consulting deliverables, project proposals, business plans
  2. Generate slides programmatically — using python-pptx to produce .pptx files from scratch
  3. Apply professional design — McKinsey / BCG / Bain consulting style, clean flat design, no shadows or gradients
  4. Build specific slide types — cover pages, data dashboards, 2x2 matrices, timelines, funnels, team introductions, executive summaries, comparison layouts
  5. Fix PPT issues — file corruption ("needs repair"), shadow/3D artifacts, inconsistent fonts, Chinese text rendering problems
  6. Maintain design consistency — unified color palette, font hierarchy, spacing, and line treatments across all slides

Core Design Philosophy

McKinsey Design Principles

  1. Extreme Minimalism - Remove all non-essential visual elements

    • No color blocks unless absolutely necessary
    • Lines: thin, flat, no shadows or 3D effects
    • Shapes: simple, clean, no gradients
    • Text: clear hierarchy, maximum readability

  2. Consistency - Repeat visual language across all slides

    • Unified color palette (navy + cyan + grays)
    • Consistent font sizes and weights for same content types
    • Aligned spacing and margins
    • Matching line widths and styles

  3. Hierarchy - Guide viewer through information

    • Title bar (22pt) → Sub-headers (18pt) → Body (14pt) → Details (9pt)
    • Navy for primary elements, gray for secondary, black for divisions
    • Visual weight through bold, color, size (not through effects)

  4. Flat Design - No 3D, shadows, or gradients

    • Pure solid colors only
    • All lines are simple strokes with no effects
    • Shapes have no shadow or reflection effects
    • Circles are solid fills, not 3D spheres

Design Specifications

Color Palette

All colors in RGB format for python-pptx:

Color Name Hex RGB Usage Notes
NAVY #051C2C (5, 28, 44) Primary, titles, circles Corporate, formal tone
CYAN #00A9F4 (0, 169, 244) Originally used in v1 DEPRECATED - Use NAVY for consistency
WHITE #FFFFFF (255, 255, 255) Backgrounds, text On navy backgrounds only
BLACK #000000 (0, 0, 0) Lines, text separators For clarity and contrast
DARK_GRAY #333333 (51, 51, 51) Body text, descriptions Main content text
MED_GRAY #666666 (102, 102, 102) Secondary text, labels Softer tone than DARK_GRAY
LINE_GRAY #CCCCCC (204, 204, 204) Light separators, table rows Table separators only
BG_GRAY #F2F2F2 (242, 242, 242) Background panels Takeaway/highlight areas

Key Rule: Use navy (#051C2C) everywhere, especially for:

  • All circle indicators (A, B, C, 1, 2, 3)
  • All action titles
  • All primary section headers
  • All TOC highlight colors

Typography System

Font Families

English Headers:  Georgia (serif, elegant)
English Body:     Arial (sans-serif, clean)
Chinese (ALL):    KaiTi (楷体, traditional brush style)
                  (fallback: SimSun 宋体)

Critical Implementation:

def set_ea_font(run, typeface='KaiTi'):
    """Set East Asian font for Chinese text"""
    rPr = run._r.get_or_add_rPr()
    ea = rPr.find(qn('a:ea'))
    if ea is None:
        ea = rPr.makeelement(qn('a:ea'), {})
        rPr.append(ea)
    ea.set('typeface', typeface)

Every paragraph with Chinese text MUST apply set_ea_font() to all runs.

Font Size Hierarchy

Size Type Examples Notes
44pt Cover Title "项目名称" Cover slide only, Georgia
28pt Section Header "目录" (TOC title) Largest body content, Georgia
24pt Subtitle Tagline on cover Cover slide only
22pt Action Title Slide title bars Main content titles, bold, Georgia
18pt Sub-Header Column headers, section names Supporting titles
16pt Emphasis Text Bottom takeaway on slide 8 Callout text, bold
14pt Body Text Tables, lists, descriptions PRIMARY BODY SIZE, all main content
9pt Footnote Source attribution Smallest, gray color only

No other sizes should be used - stick to this hierarchy exclusively.

Line Treatment (CRITICAL)

Line Rendering Rules

  1. All lines are FLAT - no shadows, no effects, no 3D
  2. Remove theme style references - prevents automatic shadow application
  3. Solid color only - no gradients or patterns
  4. Width varies by context - see table below

Line Width Specifications

Usage Width Color Context
Title separator (under action titles) 0.5pt BLACK Below 22pt title
Column/section divider (under headers) 0.5pt BLACK Below 18pt headers
Table header line 1.0pt BLACK Between header and first row
Table row separator 0.5pt LINE_GRAY (#CCCCCC) Between table rows
Timeline line (roadmap) 0.75pt LINE_GRAY Background for phase indicators
Cover accent line 2.0pt NAVY Decorative bottom-left on cover
Column internal divider 0.5pt BLACK Between "是什么" and "独到之处"

Code Implementation (v1.1 — Rectangle-based Lines)

CRITICAL: Do NOT use slide.shapes.add_connector() for lines. Connectors carry <p:style> elements that reference theme effects and cause file corruption. Instead, draw lines as ultra-thin rectangles:

def add_hline(slide, x, y, length, color=BLACK, thickness=Pt(0.5)):
    """Draw a horizontal line using a thin rectangle (no connector, no p:style)."""
    from pptx.util import Emu
    h = max(int(thickness), Emu(6350))  # minimum ~0.5pt
    return add_rect(slide, x, y, length, h, color)

IMPORTANT: Never use add_connector() — it causes file corruption. Always use add_hline() (thin rectangle).

Post-Save Full Cleanup (v1.1 — Nuclear Sanitization)

After prs.save(outpath), ALWAYS run full cleanup that sanitizes both theme XML and all slide XML:

import zipfile, os
from lxml import etree

def full_cleanup(outpath):
    """Remove ALL p:style from every slide + theme shadows/3D."""
    tmppath = outpath + '.tmp'
    with zipfile.ZipFile(outpath, 'r') as zin:
        with zipfile.ZipFile(tmppath, 'w', zipfile.ZIP_DEFLATED) as zout:
            for item in zin.infolist():
                data = zin.read(item.filename)
                if item.filename.endswith('.xml'):
                    root = etree.fromstring(data)
                    ns_p = 'http://schemas.openxmlformats.org/presentationml/2006/main'
                    ns_a = 'http://schemas.openxmlformats.org/drawingml/2006/main'
                    # Remove ALL p:style elements from all shapes/connectors
                    for style in root.findall(f'.//{{{ns_p}}}style'):
                        style.getparent().remove(style)
                    # Remove shadows and 3D from theme
                    if 'theme' in item.filename.lower():
                        for tag in ['outerShdw', 'innerShdw', 'scene3d', 'sp3d']:
                            for el in root.findall(f'.//{{{ns_a}}}{tag}'):
                                el.getparent().remove(el)
                    data = etree.tostring(root, xml_declaration=True,
                                          encoding='UTF-8', standalone=True)
                zout.writestr(item, data)
    os.replace(tmppath, outpath)

Text Box & Shape Treatment

Text Box Padding

All text boxes must have consistent internal padding to prevent text touching edges:

bodyPr = tf._txBody.find(qn('a:bodyPr'))
# All margins: 45720 EMUs = ~0.05 inches
for attr in ['lIns','tIns','rIns','bIns']:
    bodyPr.set(attr, '45720')

Vertical Anchoring

Text must be anchored correctly based on usage:

Content Type Anchor Code Notes
Action titles MIDDLE anchor='ctr' Centered vertically in bar
Body text TOP anchor='t' Default, aligns to top
Labels CENTER anchor='ctr' For circle labels 
anchor_map = {
    MSO_ANCHOR.MIDDLE: 'ctr', 
    MSO_ANCHOR.BOTTOM: 'b', 
    MSO_ANCHOR.TOP: 't'
}
bodyPr.set('anchor', anchor_map.get(anchor, 't'))

Shape Styling

All shapes (rectangles, circles) must have:

  • Solid fill color (no gradients)
  • NO border/line (shape.line.fill.background())
  • p:style removed immediately after creation (_clean_shape())
  • No shadow effects (enforced by both inline cleanup and post-save full_cleanup)
def _clean_shape(shape):
    """Remove p:style from any shape to prevent effect references."""
    sp = shape._element
    style = sp.find(qn('p:style'))
    if style is not None:
        sp.remove(style)

shape = slide.shapes.add_shape(MSO_SHAPE.RECTANGLE, left, top, width, height)
shape.fill.solid()
shape.fill.fore_color.rgb = BG_GRAY
shape.line.fill.background()  # CRITICAL: removes border
_clean_shape(shape)            # CRITICAL: removes p:style

Layout Patterns

Slide Dimensions

prs.slide_width = Inches(13.333)
prs.slide_height = Inches(7.5)

Widescreen format (16:9), standard for all presentations.

Standard Margin/Padding

Position Size Usage
Left margin 0.8" Default left edge
Right margin 0.8" Default right edge
Top (below title) 1.4" Content start position
Bottom 7.05" Source text baseline
Title bar height 0.9" Action title bar
Title bar top 0.15" From slide top

Slide Type Patterns

1. Cover Slide (Slide 1)

Layout:

  • Navy bar at very top (0.05" height)
  • Main title centered (44pt, Georgia, navy) at y=2.2"
  • Subtitle (24pt, dark gray) at y=3.5"
  • Date/info (14pt, med gray) at y=4.5"
  • Decorative navy line at x=1", y=6.8" (2" wide, 2pt)

Code template:

s1 = prs.slides.add_slide(prs.slide_layouts[6])
add_rect(s1, 0, 0, prs.slide_width, Inches(0.05), NAVY)
add_text(s1, Inches(1), Inches(2.2), Inches(11), Inches(1.0),
         '项目名称', font_size=Pt(44), font_name='Georgia',
         font_color=NAVY, bold=True, ea_font='KaiTi')
add_text(s1, Inches(1), Inches(3.5), Inches(11), Inches(0.6),
         '副标题描述', font_size=Pt(24),
         font_color=DARK_GRAY, ea_font='KaiTi')
add_text(s1, Inches(1), Inches(4.5), Inches(11), Inches(0.5),
         '演示文稿  |  2026年3月', font_size=BODY_SIZE,
         font_color=MED_GRAY, ea_font='KaiTi')
add_line(s1, Inches(1), Inches(6.8), Inches(4), Inches(6.8),
         color=NAVY, width=Pt(2))

2. Action Title Slide (Most Content Slides)

Every main content slide has this structure:

┌─────────────────────────────────────────┐ 0.15"
│ ▌ Action Title (22pt, bold, black)      │ ← TITLE_BAR_H = 0.9"
├─────────────────────────────────────────┤ 1.05"
│                                         │
│  Content area (starts at 1.4")          │
│  [Tables, lists, text, etc.]            │
│                                         │
│                                         │
│  ──────────────────────────────────────  │ 7.05"
│  Source: ...                            │ 9pt, med gray
└─────────────────────────────────────────┘ 7.5"

Code pattern:

s = prs.slides.add_slide(prs.slide_layouts[6])
add_action_title(s, 'Slide Title Here')
# Then add content below y=1.4"
add_source(s, 'Source attribution')

3. Table Layout (Slide 4 - Five Capabilities)

Structure:

  • Header row with column names (BODY_SIZE, gray, bold)
  • 1.0pt black line under header
  • Data rows (1.0" height each, 14pt text)
  • 0.5pt gray line between rows
  • 3 columns: Module (1.6" wide), Function (5.0"), Scene (5.1")
# Headers
add_text(s4, left, top, width, height, text,
         font_size=BODY_SIZE, font_color=MED_GRAY, bold=True)

# Header line (thicker)
add_line(s4, left, top + Inches(0.5), left + full_width, top + Inches(0.5),
         color=BLACK, width=Pt(1.0))

# Rows
for i, (col1, col2, col3) in enumerate(rows):
    y = header_y + row_height * i
    add_text(s4, left, y, col1_w, row_h, col1, ...)
    add_text(s4, left + col1_w, y, col2_w, row_h, col2, ...)
    add_text(s4, left + col1_w + col2_w, y, col3_w, row_h, col3, ...)
    # Row separator
    add_line(s4, left, y + row_h, left + full_w, y + row_h,
             color=LINE_GRAY, width=Pt(0.5))

4. Three-Column Overview (Slide 5)

Layout:

  • Left column (4.1" wide): "是什么"
  • Middle column (4.1" wide): "独到之处"
  • Right 1/4 (2.5" wide) gray panel: "Key Takeaways"
0.8"  4.9"  5.3"  9.4"  10.0" 12.5"
|-----|-----|-----|-----|------|
│左 │ │ 中 │ │ 右 │
└─────────────────────────────┘

Code:

left_x = Inches(0.8)
col_w5 = Inches(4.1)
mid_x = Inches(5.3)
takeaway_left = Inches(10.0)
takeaway_width = Inches(2.5)

# Left column
add_text(s5, left_x, content_top, col_w5, ...)
add_text(s5, left_x, content_top + Inches(0.6), col_w5, ..., 
              bullet=True, line_spacing=Pt(8))

# Right gray takeaway area
add_rect(s5, takeaway_left, Inches(1.2), takeaway_width, Inches(5.6), BG_GRAY)
add_text(s5, takeaway_left + Inches(0.15), Inches(1.35), takeaway_width - Inches(0.3), ...,
         'Key Takeaways', font_size=BODY_SIZE, color=NAVY, bold=True)
add_text(s5, takeaway_left + Inches(0.15), Inches(1.9), takeaway_width - Inches(0.3), ...,
              [f'{i+1}. {t}' for i, t in enumerate(takeaways)], line_spacing=Pt(10))

Common Issues & Solutions

Problem 1: PPT Won't Open / "File Needs Repair"

Cause: Shapes or connectors carry <p:style> with effectRef idx="2", referencing theme effects (shadows/3D)

Solution (three-layer defense):

  1. Never use connectors — use add_hline() (thin rectangle) instead of add_connector()
  2. Inline cleanup — every add_rect() and add_oval() calls _clean_shape() to remove p:style
  3. Post-save cleanup — full_cleanup() removes ALL <p:style> from every slide XML + theme effects

Problem 2: Text Not Displaying Correctly in PowerPoint

Cause: Chinese characters rendered as English font instead of KaiTi

Solution:

  • Use set_ea_font(run, 'KaiTi') in every paragraph with Chinese text
  • Call it inside the loop that creates runs: 
    for run in p.runs:
    set_ea_font(run, 'KaiTi')

Problem 3: Font Sizes Inconsistent Across Slides

Cause: Using custom sizes instead of defined hierarchy

Solution:

  • Define constants: 
    TITLE_SIZE = Pt(22)
BODY_SIZE = Pt(14)
SUB_HEADER_SIZE = Pt(18)
LABEL_SIZE = Pt(14)
SMALL_SIZE = Pt(9)
  • Use these constants everywhere
  • Never use arbitrary sizes like Pt(13) or Pt(15)

Problem 4: Columns/Lists Not Aligning Vertically

Cause: Mixing different line spacing or not accounting for text height

Solution:

  • Use consistent line_spacing=Pt(N) in add_text() calls
  • Calculate row heights in tables based on actual text size:
    • For 14pt text with spacing: use 1.0" height minimum
    • For lists with bullets: use 0.35" height per line + 8pt spacing
  • Test by saving and opening in PowerPoint to verify alignment

Edge Cases

Handling Large Presentations (20+ Slides)

  • Break generation into batches of 5-8 slides, saving and verifying after each batch
  • Always call full_cleanup() once at the end, not per-batch
  • Memory: python-pptx holds the entire presentation in memory; for 50+ slides, monitor usage

Font Availability

  • KaiTi / SimSun may not be installed on non-Chinese systems — the presentation will render but fall back to a default CJK font
  • Georgia is available on Windows/macOS by default; on Linux, install ttf-mscorefonts-installer
  • If target audience uses macOS only, consider using PingFang SC as ea_font fallback

Slide Dimensions

  • All layouts assume 13.333" × 7.5" (widescreen 16:9). Using 4:3 or custom sizes will break coordinate calculations
  • If custom dimensions are required, scale all Inches() values proportionally

PowerPoint vs LibreOffice

  • Generated files are optimized for Microsoft PowerPoint (Windows/macOS)
  • LibreOffice Impress may render fonts and spacing slightly differently
  • full_cleanup() is still recommended for LibreOffice compatibility

Best Practices

  1. Always start from scratch - Don't try to edit existing .pptx files with python-pptx; regenerate
  2. Test early - Save and open in PowerPoint after every 2-3 slides to catch issues
  3. Use constants - Define all colors, sizes, positions as named constants at the top
  4. Keep code DRY - Use helper functions like add_text(), add_hline(), add_oval(), etc.
  5. Never use connectors - Always draw lines as thin rectangles via add_hline()
  6. Validate XML - After full_cleanup(), verify zero p:style and zero shadows remain
  7. Document decisions - Comment code explaining why specific colors/sizes are chosen
  8. Version control - Save Python generation script alongside .pptx output

Dependencies

  • python-pptx >= 0.6.21 - For PowerPoint generation
  • lxml - For XML processing during theme cleanup
  • zipfile (built-in) - For PPTX manipulation
  • Python 3.8+

Install with:

pip install python-pptx lxml

Example: Complete Minimal Presentation

See scripts/minimal_example.py for a complete, working example that generates:

  • Cover slide
  • Table of contents
  • Content slide with title + body text
  • Source attribution
  • Proper theme cleanup

File References

Generated presentations are typically saved to:

./output/presentation.pptx

All colors, fonts, and dimensions referenced in code should match this document exactly.
