1. WhatsApp DP (Display Picture) Guide
WhatsApp displays profile pictures in two contexts: a square view in media galleries and a circular masked crop in conversation lists, groups, and contact cards. When you upload an unedited landscape or portrait photo, the edges are automatically clipped.
The Circular Masking Trap
The circular mask cuts off all four corners of your 1:1 square file. Keep all facial features, family members, or company logos within the central 70% diameter circle (approximately 350px within a 500x500px image).
Recommended Formatting Steps
Upload your photo above, set the aspect ratio to 1:1 Square (500x500 px), use the crop tool to center your subject with generous margins, and download as JPG at 90% quality.
2. Facebook Cover Photo Safe Zones
Facebook applies responsive cropping to cover photos: on desktop monitors it displays as a wide horizontal strip (820 × 312 px), while on smartphones it displays taller (640 × 360 px), cropping the left and right outer sides.
The Universal Safe Canvas Rule
To display properly on both mobile and desktop without text amputation:
- Design your base graphic at 820 × 360 pixels.
- Desktop will clip 24px from top and bottom.
- Mobile will clip 90px from left and right.
- Confine all headlines, dates, taglines, and call-to-action buttons within the central 640 × 312 px bounding zone.
3. LinkedIn Personal & Company Banner Guide
A customized LinkedIn banner immediately conveys credibility. With a panoramic 4:1 aspect ratio (1584 × 396 px), the single biggest mistake professionals make is centering their text headline—only to have it hidden behind their profile headshot.
Desktop Profile Headshot Overlay
The circular profile photo overlays the lower-left corner of the personal banner (covering up to 200px from the left and 100px from the bottom). Always position your value proposition text and certifications on the right two-thirds.
Company Page Differences
Company Page banners use a much slimmer dimension of 1128 × 191 px (~5.91:1). The company square logo overlays the lower-left, requiring clean right-aligned typography and minimal clutter.
Frequently Asked Questions
Why does WhatsApp crop my full photo when setting a DP?
WhatsApp requires a strict 1:1 square aspect ratio which is further clipped into a circle in chat lists. Pre-formatting your image to 500x500 px with a 15% margin ensures your entire subject stays inside the circular safe zone.
What is the best dimension for a Facebook Cover photo across desktop and mobile?
Upload at 820 × 360 pixels. On desktop it displays at 820 × 312 px (cropping top/bottom), while on mobile it displays at 640 × 360 px (cropping sides). Keeping all text and logos inside the central 640 × 312 px zone guarantees visibility across all devices.
Where should I place text on a LinkedIn personal profile banner?
On desktop, your circular profile headshot overlays the bottom-left area of your 1584 × 396 px banner. Always place your name, title, contact details, and brand value proposition on the right-hand two-thirds of the banner.
