How to Create a Featured Blog Post Image

Updated · Standard formula, shown below

This guide walks you through creating a featured image for a blog post—the main thumbnail that appears in search results, social media shares, and your blog’s homepage. You’ll learn the standard dimensions, design principles, and step-by-step methods using free tools, so your posts look professional and attract clicks. No prior design experience is needed.

What You’ll Need

  • A computer or tablet with internet access
  • A free or paid image editor (Canva, Figma, GIMP, or Photoshop)
  • Your blog post title and a short list of key points or keywords
  • Optional: brand colors, logo, and fonts
  • Optional: royalty-free stock photos (e.g., Unsplash, Pexels)

Step-by-Step

  1. Choose the correct dimensions. The most common featured image size is 1200×630 pixels (about 16:9 aspect ratio). This works for social media, most blog themes, and Google search results. If your theme specifies a different size (check your theme’s documentation), use that instead.
  2. Open your design tool and create a new project. In Canva, click “Create a design” and enter the custom size 1200×630 px. In Figma, create a frame with those dimensions. In GIMP or Photoshop, create a new file with those width and height values.
  3. Set a background. Choose a solid color that matches your brand, a subtle gradient, or a relevant photo. If using a photo, ensure it has enough contrast for text overlay. You can also add a semi-transparent overlay (e.g., a dark rectangle with 50% opacity) to make text readable.
  4. Add your title text. Keep it short—ideally under 8 words. Use a bold, readable font. Place the text in the center-left or center of the image, leaving some margin (at least 50 px) from the edges. Avoid placing text in the bottom-right corner, as social media icons may cover it.
  5. Incorporate a visual element. Add an icon, illustration, or a cropped photo that supports the post’s topic. For example, if the post is about “10 Easy Vegan Recipes,” use a photo of a colorful salad or a simple food icon. Keep the visual balanced—not too busy.
  6. Apply your brand colors and fonts. If you have a style guide, use your brand’s color palette and font pairings. This helps readers recognize your content instantly. If not, pick 2-3 colors that complement each other (use a tool like Coolors for inspiration).
  7. Add a subtle border or frame (optional). A thin border (e.g., 2-5 px) in a contrasting color can make the image pop on white backgrounds. Avoid thick borders that distract.
  8. Export the image. Save as JPG (recommended for photos) or PNG (if you need transparency). Use the highest quality setting. Name the file descriptively, e.g., “vegan-recipes-featured.jpg” (use hyphens, not spaces).
  9. Upload to your blog. In WordPress, use the “Set featured image” option in the post editor. In other platforms, look for a “Cover image” or “Thumbnail” field. After uploading, check that the image appears correctly on your homepage and in social shares.
  10. Test the image on social media. Use a tool like the Facebook Sharing Debugger or LinkedIn Post Inspector to see how your link preview looks. If the image is cropped or text is cut off, adjust the design accordingly (e.g., move text more toward the center).

Common Mistakes

  • Using the wrong dimensions. A 500×500 square image will be cropped awkwardly on social media and may look blurry on high-resolution screens. Always start with 1200×630 px.
  • Text too small or too long. If your title wraps to 3+ lines, it becomes unreadable on mobile. Shorten the title or increase font size.
  • Low-contrast text. White text on a light background is invisible. Always ensure a high contrast ratio (e.g., dark text on light background or vice versa).
  • Overcrowding with elements. Too many icons, shapes, or photos make the image look cluttered and amateur. Keep it simple—one focal point.
  • Ignoring the theme’s crop. Your blog theme may crop the image to a different ratio (e.g., 4:3 or 1:1). Check how it displays and adjust your design to keep important elements within the safe area.

Tips

  • Use a template. Most tools offer free featured image templates. Start with one and customize it—saves time and ensures a professional look.
  • Keep a consistent style. Use the same font family, color scheme, and layout across all your featured images. This builds brand recognition.
  • Design for mobile. More than half of your readers will see the image on a phone. Make sure text is legible at small sizes (test by zooming out).
  • Include a human element (if relevant). Faces attract attention. A photo of a person (even a cropped face) can increase engagement.
  • Use free stock photos wisely. Choose images with negative space (empty areas) where you can place text. Avoid busy backgrounds.
  • Reuse your best designs. If a particular layout works well, save it as a template and swap out the text and photo for future posts.

Troubleshooting

  • Image is blurry when uploaded. This usually means the source file is too small. Re-export at 1200×630 px at 100% quality. If your platform compresses images, try uploading a larger version (e.g., 2400×1260 px) and let the platform downscale.
  • Text is cut off on social media. Social platforms crop images in previews. Keep all important content within the central 600×315 px area (the “safe zone”). Use the platform’s preview tool to adjust.
  • Image doesn’t appear in Google search. Ensure your blog post has an Open Graph tag (most themes do this automatically). If not, install an SEO plugin like Yoast or Rank Math. Also, submit your sitemap to Google Search Console.
  • Colors look different on screen vs. print. This is normal due to color profiles. For digital use, stick to RGB color mode (not CMYK).
  • Can’t find the “Set featured image” option. In WordPress, it’s usually in the right sidebar under “Post” → “Featured image.” If you don’t see it, click “Screen Options” at the top and check the box.

Frequently Asked Questions

What is the best size for a featured image?

The most widely recommended size is 1200×630 pixels. It fits most blog themes and social media platforms. However, always check your theme’s documentation for any specific requirements.

Can I use a free tool to create featured images?

Yes. Canva (free tier), Figma (free tier), and GIMP (open source) are all excellent options. They offer templates, text tools, and export options without needing paid software.

Should the featured image include the post title?

Yes, it’s common and effective to include a short version of your title. This helps readers understand the content at a glance, especially when the image is shared without context.

How do I make my featured image stand out in search results?

Use high contrast, bold text, and a clear focal point. Also, ensure the image is properly compressed (under 200 KB) so it loads quickly. Use descriptive alt text with keywords.

Can I reuse the same image for multiple posts?

It’s not recommended, as it can confuse readers and hurt your SEO. Each post should have a unique image that reflects its specific content.

What is the difference between a featured image and a header image?

A featured image is the thumbnail that represents your post in lists and social shares. A header image is the large banner at the top of the article. Some themes use the same image for both, but they can be different.
