Hubspot Blog Image Size Guide for Faster, Better Posts

When you build content in Hubspot, properly sizing and optimizing your blog images is critical for fast load times, clear layouts, and a better reader experience. This guide walks you through practical steps to choose the right dimensions, compress files, and align images so your posts look clean and professional on every device.

Why Image Size Matters in Hubspot Blog Posts

Large, unoptimized images can slow your Hubspot pages, hurt search rankings, and distract readers from your message. On the other hand, images that are too small or stretched look unprofessional and can break layout consistency.

Getting image sizing right helps you:

• Improve page load speed and Core Web Vitals
• Keep blog layouts consistent and readable
• Avoid blurry or pixelated visuals
• Support accessibility and UX on mobile and desktop

The original Hubspot tutorial on image sizing also highlights that images should support your content, not overwhelm it. Aim for balance between visual appeal and performance.

Recommended Hubspot Blog Image Dimensions

While Hubspot can scale images responsively, you will get the best results if you upload files close to the size they will appear on the page. The following recommendations are based on the guidance from the original tutorial at this Hubspot help article.

Hubspot Featured Image Recommendations

The featured image is usually displayed at the top of your blog post and in listing pages or social previews. Aim for:

• Width: around 1200 pixels
• Height: 628–800 pixels (or a 3:2 to 16:9 ratio)
• Format: JPG or WebP for photos; PNG or WebP for graphics

Pick a size that looks sharp on large screens without being unnecessarily heavy. A compressed image under a few hundred kilobytes usually works well.

Hubspot In-line Blog Image Dimensions

In-line images appear inside the body of your Hubspot article. They should fit the content width of your theme and not dominate the screen.

• Full-width in the post body: 700–900 pixels wide
• Half-width or side-by-side images: 400–600 pixels wide
• Icons or small graphics: 150–300 pixels wide

Use consistent widths for similar image types across your Hubspot blog so readers can quickly scan your content.

Step-by-Step: How to Resize Images for Hubspot

Before you upload images to Hubspot, resize them locally to reduce file size and maintain sharpness. Follow these steps on any standard image editor or online tool.

1. Decide How the Image Will Be Used in Hubspot

First, determine whether the image will be:

• A featured image
• A main in-line visual (e.g., a chart or screenshot)
• A small supporting image or icon

Your intended use determines the target width and aspect ratio.

2. Crop to the Right Aspect Ratio

Use cropping to remove unnecessary edges and focus on the subject. Common ratios for Hubspot blog content include:

• 16:9 or 3:2 for featured images
• 4:3 or free-form for in-line screenshots
• Square (1:1) for icons or small graphics

Cropping to a clean ratio helps your images align smoothly with Hubspot’s responsive layouts.

3. Resize to Recommended Pixel Width

Set the width to match your plan:

• Featured image: about 1200px wide
• Main body image: 700–900px wide
• Small graphics: 150–300px wide

Let the height adjust automatically to avoid distortion. Verify that text within screenshots remains readable after resizing.

4. Compress the File Before Uploading to Hubspot

After resizing, compress the image to reduce file size without losing visible quality. You can use:

• Online compression tools (lossy or lossless)
• Built-in export settings in your image editor
• Modern formats such as WebP when supported

As a rule of thumb, keep most blog images under 200KB when possible, and only go higher for complex graphics that truly need extra detail.

Formatting Images Inside the Hubspot Editor

Once images are prepared and uploaded to your Hubspot file manager, refine how they appear in the editor to keep layouts clean.

Using Alignment Options in Hubspot

When you insert an image into the Hubspot rich text editor, you will see alignment tools such as:

• Full-width (center): ideal for main visuals, charts, and screenshots
• Left or right aligned: good for small images with text wrapping
• No wrap: places the image on its own line

Use center alignment for important images that need full attention and left or right alignment for secondary visuals that support surrounding text.

Setting On-Page Dimensions in Hubspot

After placing an image in the editor, you can fine-tune its display size:

1. Click the image inside the Hubspot editor.
2. Open the image settings or style options.
3. Adjust width as a percentage (e.g., 50%, 75%, 100%) or as a pixel value.
4. Preview the post to confirm how it looks on different screen sizes.

Using percentage-based widths can help images scale more naturally on mobile devices.

Maintaining Consistency Across the Hubspot Blog

To keep a professional look, define a simple style guide for your Hubspot content team, such as:

• Standard featured image width and ratio
• Default width for in-line screenshots
• Alignment rules (e.g., main visuals centered, small decorative images right-aligned)
• Maximum number of large images per post

Consistency improves readability and makes future posts easier to design.

Optimizing Hubspot Images for SEO and Accessibility

Beyond size and layout, add basic SEO and accessibility elements to every image you publish in Hubspot.

Write Clear Alt Text in Hubspot

Alt text helps search engines and screen readers understand your images. Inside Hubspot, edit each image and add a short, descriptive phrase such as:

• “Screenshot of Hubspot blog editor with image alignment options”
• “Chart showing monthly website traffic growth”
• “Product photo on white background”

Avoid keyword stuffing; describe what the image truly shows.

Use Descriptive File Names Before Uploading

Rename files before uploading them to Hubspot. Replace generic names like IMG_1234.png with something meaningful, for example:

• hubspot-blog-image-editor.png
• marketing-dashboard-traffic-chart.jpg

Descriptive filenames provide extra context for search engines and make your file manager easier to maintain.

Testing Your Hubspot Blog Images Before Publishing

Always preview your Hubspot post on multiple devices to verify that images render correctly.

1. Use the preview feature: Check desktop, tablet, and mobile layouts.
2. Scan load speed: Ensure pages load promptly and images do not cause noticeable delays.
3. Check readability: Confirm that text on screenshots is sharp and legible.
4. Validate spacing: Make sure there is enough white space around images.

If images feel too dominant, reduce their width, crop closer to the subject, or replace them with simpler graphics.
