2. Right-Click Properties on Windows

A classic and simple method:

• Right-click on the image file
• Select “Properties”
• Click the “Details” tab
• Look under “Image” for dimensions

It’s built-in and doesn’t require any extra software, though it’s not ideal for bulk checking or advanced needs.

3. Use Preview on Mac

macOS users can check dimensions natively:

• Open the image in Preview
• Go to “Tools” → “Show Inspector”
• Navigate to the “i” tab
• See pixel dimensions instantly

This is quick and efficient for single images and works flawlessly for high-res photos.

4. Inspect Element in Your Browser

Want to check dimensions for web images without downloading them?
Just right-click the image → “Inspect” → hover over the <img> tag, and the natural and rendered sizes will appear in a tooltip.

Perfect for web developers or social media managers analyzing site content.

5. Use Photoshop for Precise Measurements

Photoshop is a goldmine for professional editing.

• Open your image
• Go to “Image” → “Image Size”
• You’ll see pixel dimensions, print size, and DPI

While not the fastest for casual users, it’s ideal for professionals who need pixel-perfect data.

6. Use Terminal or Command Line Tools

For Linux/macOS pros, try the identify command from ImageMagick:

bashCopyEditidentify -format "%wx%h" image.jpg

It gives exact dimensions and is scriptable for bulk checking.

Not for everyone, but unbeatable for power users.

7. Use EXIF Metadata Viewers

Some EXIF tools (like Pixfav’s EXIF Viewer) show not just camera data but image resolution too.

They’re helpful when you want extra metadata along with dimensions (e.g., DPI, model, orientation, etc.)

8. Check Image Info in Mobile Gallery

Android and iOS galleries often show dimensions:

• Tap the image
• Tap “Info” or the “i” icon
• See resolution and file size

Simple, fast, and no apps needed—especially handy for social media managers working from their phones.

9. Drag-and-Drop Image Tools (No Install)

🤔 FAQs: Everything You Need to Know About Checking Image Dimensions

Q1. What is the difference between resolution and dimensions?

Dimensions refer to the width and height in pixels, while resolution (e.g., 300 DPI) refers to pixel density in print

Q2. Why do image dimensions matter for web use?

Web platforms like Instagram, Facebook, or websites have dimension limits. Using the right size ensures quality and fast loading.

Q3. Can incorrect dimensions affect SEO?

Yes! Large, unoptimized images can slow down page speed, affecting SEO rankings.

Q4. Do image dimensions affect DPI?

No. DPI affects print size, while dimensions affect digital display. They are stored separately in image metadata.

Q5. Can I check dimensions without uploading online?

Absolutely! Use system tools like Windows Explorer, Preview on Mac, or Photoshop for offline checking.

Q6. What is the ideal size for Instagram or Facebook?

It varies! For Instagram posts: 1080×1080 px; Facebook cover photo: 820×312 px. Use dedicated resizer tools.

Q7. Do image formats affect dimensions?

No. PNG, JPG, WebP—all store width and height similarly. Format affects compression and quality, not size.

🧠 Pro Tip: Use a Bulk Dimension Checker for Workflows

If you work with many images daily (e.g., bloggers, ecommerce sellers, marketers), use a batch image size checker. Combine it with Pixfav’s tools for resizing, cropping, or converting for a streamlined workflow.
