You open the OG Image Generator. There are five template buttons: Minimal, Dark, Gradient, Bold, Clean. Which one do you pick? It depends on your content, your audience, and where you're sharing. I tested each template side by side with the same headline — here's what I found and how to choose.
The Five Templates at a Glance
I typed the same headline into the OG Image Generator, clicked through each template, and inspected the rendered preview. Here's what each template does and what it's best for.
| Template | Background | Title Style | Unique Feature | Best For |
|---|---|---|---|---|
| Minimal | White (#ffffff) | 72px, 800 weight, centered | Nothing but text — pure typography | Professional, corporate, minimalist brands |
| Dark | Dark navy (#0f172a) | 68px, 800 weight, centered | Maximum contrast — 15:1 ratio | Light-mode feeds, premium feel, tech blogs |
| Gradient | Indigo to purple linear gradient | 64px, 800 weight, centered | Vibrant multi-color background | Creative content, marketing, standing out |
| Bold | Red (#ef4444) | 88px, 900 weight, left-aligned | White accent bar on the left, oversized headline | Announcements, strong statements, call-to-action |
| Clean | Light blue (#f0f9ff) | 64px, 700 weight, centered | Thin blue top accent bar | SaaS, tech, business, and educational content |
Minimal: When Less Is Everything
The Minimal template is a white background with dark text. That's it. No accent bars, no gradient, no decorative elements. The title renders at 72px with 800 weight, centered in the canvas.
I tested this with a headline about “What Is an OG Image?” — a beginner-friendly topic. The white background and large, bold title gave the card a clean, authoritative look. On LinkedIn's light-mode feed, the card sat naturally without clashing. On Twitter/X dark mode, the white background created a distinct floating card effect — it didn't blend in.
Choose Minimal when: your brand uses a clean aesthetic, you want the title to be the single visual focus, or you're sharing on platforms where you don't want to compete with color noise. Professional services, consulting content, and thought leadership pieces pair well with this template.
Dark: Built for Contrast
The Dark template uses a deep navy background (#0f172a) with near-white text (#f8fafc). The contrast ratio is roughly 15:1 — well above the WCAG AAA standard. The title is 68px, 800 weight, centered.
I tested Dark with the same headline as Minimal. On LinkedIn's white feed, the card stands out immediately — the dark background acts as a visual anchor against the light UI. On Twitter/X light mode, it has the same effect. On Twitter/X dark mode, the dark navy card blends slightly into the dark chrome (#15202B). If your primary audience is on Twitter/X with dark mode enabled, consider a lighter background instead.
Choose Dark when: your audience is primarily on light-mode feeds (LinkedIn, Facebook, Slack), you want a premium or high-end look, or your content is tutorial-heavy (the high contrast helps readability at small thumbnail sizes). I use Dark for technical guides and comparison articles.
Gradient: Color That Catches the Eye
The Gradient template applies a linear gradient from indigo (#667eea) to purple (#764ba2) across the full background. White text at 64px, 800 weight sits centered on top. The gradient is the most visually distinct of the five templates.
I tested Gradient with a headline about color psychology for OG images. The indigo-purple gradient created a vibrant card that popped in every feed I tested it in — Facebook's blue UI, LinkedIn's blue UI, and Twitter's white/dark themes. The gradient's saturation is high enough that it doesn't disappear anywhere, but the mid-tone sections (where the gradient transitions between the two colors) reduce text contrast slightly. At full 1200×630 resolution, the text is perfectly readable. At mobile thumbnail size (around 300px wide), it's still legible but not as sharp as the Dark or Minimal templates.
Choose Gradient when: your content is creative, marketing-focused, or brand-building. Gradient cards work well for blog posts about design, social media strategy, or product launches. Avoid it for text-heavy technical content where maximum readability at thumbnail size matters more than visual flair.
Bold: Made for Impact
The Bold template is the most distinctive of the five. It uses a red background (#ef4444), a white decorative accent bar on the left side (10px wide, 60% height, vertically centered), and the title is left-aligned at 88px with 900 weight — the largest and heaviest of any template.
I tested Bold with a short headline: “50% Off — Limited Time.” The left-aligned layout with the accent bar gave it a magazine-cover feel. On social feeds, the Bold card was immediately recognizable — the red background and oversized typography stopped the scroll. The left alignment is a practical advantage: on mobile feeds where the preview card is narrow, left-aligned text survives right-side cropping better than centered text that might get clipped.
Choose Bold when: you have a short, punchy headline (under 40 characters), you're making an announcement or promotion, or you want to convey authority and urgency. One caveat: red can be polarizing — test it with your audience. For evergreen educational content, Dark or Clean may feel more appropriate.
Clean: Professional and Approachable
The Clean template uses a light blue background (#f0f9ff) with dark blue text (#0c4a6e). A thin 8px sky-blue accent bar (#0284c7) runs across the top of the card. The title is 64px, 700 weight, centered.
I tested Clean with a headline about LinkedIn preview optimization. The light blue background is professional without being sterile — it has warmth that a pure white background lacks. The top accent bar adds visual structure without distracting from the title. On LinkedIn's blue-themed feed, the lighter blue card differentiates itself enough to be noticeable while still feeling native to the platform. On Facebook, the light blue background contrasts well against the darker blue chrome.
Choose Clean when: you're creating content for SaaS, business, or educational audiences. The template strikes a balance between Minimal's restraint and Gradient's vibrancy. It's my default choice for how-to guides and tutorial content because it feels approachable without sacrificing professionalism.
How to Choose: A Decision Framework
Here's the process I use when creating a new OG image for a blog post:
- What is your headline length? Over 60 characters? Use Minimal, Dark, or Clean (they handle long text best with centered, slightly smaller titles). Under 40 characters and punchy? Try Bold.
- Where is the primary share platform? LinkedIn / Facebook (both blue UIs) — prefer Gradient, Bold, or Clean to differentiate from the blue chrome. Twitter/X — consider the reader's likely theme. Dark on dark mode blends in; Minimal provides contrast. Slack / Discord — most templates work because these platforms show the full image without aggressive cropping.
- What is your brand's visual tone? Corporate / professional — Minimal or Dark. Creative / marketing — Gradient or Bold. Technical / educational — Clean or Dark.
- Does your content have a clear visual hierarchy? If the title is the only text on the card, Minimal or Dark let the typography speak. If you need subtitle or logo, Gradient and Clean have more room for layered elements.
Test Before You Share
Whichever template you pick, always verify the result before publishing. I use our OG Checker after generating every image. Paste the URL of the page where the OG image will live, and the checker shows you:
- The exact og:image preview at full resolution
- All detected Open Graph tags (title, description, image, dimensions)
- Whether og:image:width and og:image:height are present
- How the card might render across platforms
I caught a template mismatch this way: I had generated an image using the Gradient template but the page was referencing an old Minimal image. The OG Checker showed the discrepancy immediately, saving me from sharing a broken preview.
Quick tip: After generating your image and verifying with the OG Checker, also run the URL through the relevant platform's debugger. Facebook Sharing Debugger, Twitter Card Validator, and LinkedIn Post Inspector each show platform-specific rendering quirks that the checker can't simulate.
Putting It Together
The five templates aren't ranked — they're tools for different jobs. Here's my personal shorthand:
- Dark for technical tutorials and comparisons
- Clean for how-to guides and business content
- Minimal for thought leadership and professional articles
- Gradient for creative and marketing content
- Bold for announcements and short, punchy headlines
Open the OG Image Generator, try each template with your headline, download the one that fits your content best — it takes 30 seconds per image. Then verify with the OG Checker before hitting publish. Your social shares will thank you.
