How to Make a Facebook Cover Photo Fit Mobile and Desktop

Nothing is more frustrating than designing a brilliant Facebook cover photo, only to watch it get awkwardly cropped on mobile devices. You place your logo perfectly, align your text, and then realize half of it is missing for anyone scrolling on their phone. This article gives you the exact dimensions and simple, step-by-step instructions to create a single Facebook cover photo that looks sharp and professional on both desktop and mobile, every single time.

Why Does My Cover Photo Look Weird on Mobile?

Here’s the main thing to understand: Facebook doesn't shrink your cover photo for different devices, it crops it. Your desktop view is wide and panoramic, while the mobile view is taller and narrower. Instead of creating and serving up two separate image files, Facebook uses your single uploaded image and simply shows different parts of it depending on the screen size.

Think of it like looking at a wide painting through two differently shaped windows. On a desktop, you're looking through a short, wide letterbox window, seeing the full width but with the top and bottom cut off. On a mobile device, you're looking through a taller, portrait-style window. You see more of the height but the sides get chopped off. This is why a design centered on your desktop screen can look completely off on a phone.

The goal isn’t to find a "perfect" size that works everywhere - that doesn't exist. Instead, the strategy is to create one larger image with a "safe zone" in the middle, ensuring your most important content is always visible, no matter how Facebook decides to crop it.

The "One Size Fits All" Guide: Dimensions and Safe Zone

Forget all the complicated and outdated guides you've seen online. For a cover photo that works seamlessly across devices today, you need to create your design with one specific size in mind and understand where the safe zones are located.

Your Official Dimensions Cheat Sheet

Create your design canvas at 820 pixels wide by 462 pixels tall. This is the ideal starting point designed to accommodate both desktop and mobile cropping.

• Full Canvas Size: 820px wide by 462px tall. This is the entire image you will design and upload.
• Desktop Display: Facebook will show the full 820px width but will trim the top and bottom, displaying an area of approximately 820px by 312px.
• Mobile Display: Facebook shows a centered, narrower crop of about 640px wide by 360px tall. It hides the sides of your image but shows more of the vertical center than the desktop view.

The Magic "Safe Zone"

The "safe zone" is the area of your image that is visible on both mobile and desktop. This is where you absolutely must place all your vital information - your company name, logo, tagline, or the main subject of your photograph. Anything outside this central area is at risk of being cropped on one device or another.

Based on the dimensions above, the practical All-Device Safe Zone is a bubble in the middle of your canvas, approximately 640px wide by 312px tall. Designing within this central box stops the frustration of your text or logo being cut off.

Step-by-Step Guide to Creating a Perfectly Cropped Cover Photo

Now, let's put this into practice. You can use any design tool you like, such as Canva, Figma, Adobe Express, or Photoshop. The steps are universal.

Step 1: Set Up Your Design Template

The first step is building a reusable template with guides that show you exactly where the safe zone is. You'll only need to do this once.

1. Create a new custom design or canvas with the dimensions 820 x 462 pixels.
2. Add guides or draw a temporary shape in the center. This shape should be 640 pixels wide by 312 pixels tall. Center this rectangle both horizontally and vertically.
3. Lower the opacity of this central rectangle so you can see through it. This box is now your visual guide. Everything important goes inside it.

Step 2: Place Your Content Strategically

With your template ready, you can start designing. This is where you separate what's essential from what's atmospheric background.

Inside the Safe Zone:

• Your logo or brand name.
• Your value proposition or main tagline (e.g., "Handmade Pottery" or "Book Your Consultation Today").
• The primary subject of a photo, like a person's face or a key new product.
• A short call-to-action or website link.

Outside the Safe Zone:

• Background textures, patterns, and colors that fit with your brand.
• The edges of a wider landscape photograph.
• Decorative graphics that add style but don't carry key information.

This approach gives your design a background that fills the entire space gracefully on both desktop and mobile, while protecting the core of your message. Once you're finished with the design, remember to delete or hide the guide rectangle so it doesn't appear in your final exported image.

Step 3: Upload and Check on Both Devices

Once your design is finished, save it as a high-quality JPG or PNG file.

1. Go to your Facebook page, hover over your cover photo, and click "Edit Cover Photo."
2. Select "Upload Photo" and choose your 820px by 462px image file.
3. Facebook might prompt you to reposition the image. Do not drag it. Because you designed it in the perfect dimensions, its default centered position is exactly what you want. Click "Save Changes."
4. Immediately check your page on both a desktop computer and the Facebook mobile app to see the results. On mobile, view your page as a visitor would to confirm everything looks as you planned.

Tips for a Cover Photo That Gets Clicks

Getting the dimensions right is the first step, now you can use that space effectively. Here are a few tips to make your cover photo more engaging.

• Prioritize Simplicity: A cover photo should be a simple, bold statement - more like a billboard than a brochure. Avoid cluttering the image with too much text. A single, powerful phrase combined with a compelling brand image will have a greater impact.
• Direct Attention: If your cover photo includes a person, have them look toward your logo or call-to-action. This naturally guides the viewer's eyes to the most important elements.
• Sync Your Profile &, Cover Photos: Your profile picture and cover photo should work together as a cohesive brand statement. Use a consistent color palette or style. You can even create designs where a graphic element flows from your profile picture into the cover photo, just make sure all essential content remains within the mobile-safe zone.
• Update It Regularly: Keep your cover photo fresh. Use it to announce new products, promote upcoming events, or highlight a current marketing campaign. This keeps your page dynamic and gives followers a reason to check back.
• Stay On-Brand: Your cover photo must be visually consistent with your overall brand identity, including your website and other marketing materials. Use the same fonts, colors, and level of professionalism to build brand recognition and trust.

Final Thoughts
