Social Media Carousel

Design high-engagement carousel posts via inference.sh CLI.

Quick Start

Requires inference.sh CLI (infsh). Install instructions

infsh login

# Generate a carousel slide
infsh app run infsh/html-to-image --input '{
  "html": "<div style=\"width:1080px;height:1080px;background:#0f172a;display:flex;align-items:center;justify-content:center;padding:80px;font-family:system-ui;color:white;text-align:center\"><div><p style=\"font-size:24px;color:#818cf8;text-transform:uppercase;letter-spacing:3px\">5 Rules for</p><h1 style=\"font-size:64px;margin:16px 0;font-weight:900;line-height:1.1\">Writing Headlines That Convert</h1><p style=\"font-size:22px;opacity:0.5;margin-top:24px\">Swipe →</p></div></div>"
}'

Platform Specs

Platform Dimensions Slides Aspect Ratios

Instagram 1080 x 1080 px Up to 20 1:1 (default), 4:5, 16:9

LinkedIn 1080 x 1080 px or 1080 x 1350 Up to 20 1:1, 4:5

Twitter/X 1080 x 1080 px Up to 4 1:1, 16:9

Facebook 1080 x 1080 px Up to 10 1:1, 4:5

Use 1080 x 1350 (4:5) on Instagram and LinkedIn — takes up more screen real estate in the feed than square.

Carousel Structure

The 7-Slide Framework

Slide Purpose Content

1 Hook Bold claim, question, or promise — stops the scroll

2 Context Why this matters, set up the problem

3-6 Value One point per slide, numbered

7 CTA Follow, save, share, comment, visit link

Slide 1: The Hook

The most important slide. If this fails, nobody swipes.

Hook Type Example

Bold claim "90% of landing pages make this mistake"

Question "Why do your ads get clicks but no conversions?"

Number + promise "7 Python tricks I wish I learned sooner"

Contrarian "Stop writing blog posts (do this instead)"

Before/after Show transformation

# Hook slide
infsh app run infsh/html-to-image --input '{
  "html": "<div style=\"width:1080px;height:1350px;background:linear-gradient(180deg,#1e1b4b,#312e81);display:flex;align-items:center;justify-content:center;padding:80px;font-family:system-ui;color:white;text-align:center\"><div><h1 style=\"font-size:72px;font-weight:900;line-height:1.15;margin:0\">90% of Landing Pages Make This Mistake</h1><p style=\"font-size:28px;opacity:0.6;margin-top:32px\">Swipe to find out →</p></div></div>"
}'

Slides 2-6: Content Slides

One point per slide. Never cram multiple ideas.

# Content slide template
infsh app run infsh/html-to-image --input '{
  "html": "<div style=\"width:1080px;height:1350px;background:#1e1b4b;padding:80px;font-family:system-ui;color:white;display:flex;flex-direction:column;justify-content:center\"><div><p style=\"font-size:120px;font-weight:900;color:#818cf8;margin:0;line-height:1\">01</p><h2 style=\"font-size:48px;margin:24px 0 16px;font-weight:800;line-height:1.2\">Your headline is too vague</h2><p style=\"font-size:26px;opacity:0.8;line-height:1.6\">\"Welcome to our platform\" tells the visitor nothing. Lead with the outcome: \"Ship docs in minutes, not days.\"</p></div></div>"
}'

Slide 7: CTA Slide

# CTA slide
infsh app run infsh/html-to-image --input '{
  "html": "<div style=\"width:1080px;height:1350px;background:linear-gradient(180deg,#312e81,#1e1b4b);display:flex;align-items:center;justify-content:center;padding:80px;font-family:system-ui;color:white;text-align:center\"><div><h2 style=\"font-size:56px;font-weight:900;margin:0;line-height:1.2\">Found this useful?</h2><p style=\"font-size:32px;opacity:0.8;margin-top:24px;line-height:1.5\">Save this post for later 🔖<br>Follow for more tips</p><p style=\"font-size:24px;opacity:0.4;margin-top:40px\">@yourusername</p></div></div>"
}'

Swipe Psychology

Principle Application

Curiosity gap Hook promises value that requires swiping

Numbered progress "3/7" creates completion drive

Visual continuity Consistent design signals "there's more"

Increasing value Best tip last — rewards completing

Swipe cue Arrow or "Swipe →" on slide 1

Batch Generation

# Generate all slides for a carousel
for i in 1 2 3 4 5 6 7; do
  infsh app run infsh/html-to-image --input "{
    \"html\": \"<div style='width:1080px;height:1350px;background:#1e1b4b;display:flex;align-items:center;justify-content:center;padding:80px;font-family:system-ui;color:white'><div style='text-align:center'><p style='font-size:28px;opacity:0.5'>Slide $i of 7</p></div></div>\"
  }" --no-wait
done

AI-Generated Carousel Visuals

# Generate illustrations for each slide
infsh app run falai/flux-dev-lora --input '{
  "prompt": "minimal flat illustration, person at desk with laptop, clean modern style, simple shapes, limited color palette purple and blue tones, white background, icon style",
  "width": 1080,
  "height": 1080
}'

Common Mistakes

Mistake Problem Fix

Weak hook (slide 1) Nobody swipes Bold claim, question, or number + promise

Too much text per slide Overwhelming, stops reading Max 30-40 words per slide

No visual consistency Looks like different posts Same colors, fonts, margins throughout

No swipe indicator People don't realize there's more Add "Swipe →" or arrow on slide 1

No CTA on last slide Missed engagement opportunity Ask to save, follow, share, or comment

Inconsistent numbering Feels disorganized Same number format on every content slide

Cramming 2+ ideas per slide Hard to digest One point per slide, always

Square format on Instagram Wastes feed real estate Use 1080x1350 (4:5) for more visibility
