Social Media Image Sizes 2026: Quick Reference

If you need an answer quickly, start with these commonly used dimensions:

Instagram Image Sizes 2026

Instagram supports square, portrait, landscape, Story, and Reel formats. Because Instagram is heavily mobile-focused, portrait and full-screen vertical formats are especially important.

Instagram Profile Picture Size

Recommended upload size: 320 × 320 pixels.

Your profile picture appears in a circular frame, so keep logos, faces, and other important elements near the center of the image.

Instagram Square Post Size

1080 × 1080 pixels (1:1).

The classic square format remains useful for graphics, product images, announcements, quotes, and carousel content.

Instagram Portrait Post Size

1080 × 1350 pixels (4:5).

A portrait image occupies more vertical screen space in the mobile feed than a square image, making 4:5 an excellent format for many feed posts.

Instagram Landscape Image Size

1080 × 566 pixels is a useful landscape format for Instagram.

Instagram Stories and Reels Size

1080 × 1920 pixels (9:16).

This full-screen vertical format is the standard choice for Stories and Reels. Avoid positioning critical text or logos too close to the edges because interface elements can cover portions of the screen.

Facebook Image Sizes 2026

Facebook displays content across phones and desktop screens, so choosing dimensions that adapt well to different displays is important.

Facebook Profile Picture

Recommended: 320 × 320 pixels or larger.

Facebook displays profile images as circles in many locations. Keep the important part of your image centered.

Facebook Cover Photo

Recommended: 851 × 315 pixels.

Remember that cover photos can appear differently on desktop and mobile. Keep essential branding and text away from extreme edges.

Facebook Square Post

1080 × 1080 pixels (1:1).

Facebook Portrait Post

1080 × 1350 pixels (4:5).

Facebook Landscape Post

1200 × 630 pixels is a widely used landscape format, particularly for shared-link-style visuals.

Facebook Stories and Reels

1080 × 1920 pixels (9:16).

If your existing photo doesn't match these dimensions, resize it before publishing with the free Doxvera Image Resizer.

TikTok Image and Content Sizes 2026

TikTok is designed primarily around vertical mobile content. A 9:16 aspect ratio fills the screen and is the safest starting point for full-screen TikTok content.

TikTok Vertical Size

1080 × 1920 pixels (9:16).

TikTok Profile Picture

Use a clear square source image and keep the main subject centered because the profile image is displayed in a circular frame.

For promotional graphics, avoid placing important text too close to the bottom and side areas where TikTok interface controls may appear.

YouTube Image Sizes 2026

YouTube thumbnails are particularly important because viewers often decide whether to open a video based partly on the thumbnail.

YouTube Thumbnail Size

1280 × 720 pixels (16:9).

Use a sharp, high-quality thumbnail with readable text and a clear focal point. Remember that thumbnails may be displayed at much smaller sizes on mobile devices.

YouTube Channel Banner Size

2560 × 1440 pixels is a commonly recommended channel art canvas size.

Because YouTube channel art is displayed differently depending on the device, place essential logos and text toward the center safe area.

YouTube Profile Image

A high-resolution square image works best. Keep the logo or main visual centered so it remains recognizable when displayed at smaller sizes.

LinkedIn Image Sizes 2026

LinkedIn image dimensions matter for personal profiles, Company Pages, organic posts, and link previews.

LinkedIn Profile Picture

400 × 400 pixels or larger is recommended for personal profile photos.

LinkedIn Personal Cover Photo

1584 × 396 pixels (4:1).

LinkedIn Company Page Cover

1128 × 191 pixels.

LinkedIn Square Post

1200 × 1200 pixels is a strong square format.

LinkedIn Link Image

1200 × 627 pixels is a commonly recommended size for images accompanying URLs.

X (Twitter) Image Sizes 2026

X supports multiple image orientations, including square, landscape, and vertical formats.

X Profile Picture

400 × 400 pixels.

X Header Image

1500 × 500 pixels (3:1).

X Landscape Post Image

1600 × 900 pixels (16:9) is a useful high-resolution landscape format.

X Square Image

1080 × 1080 pixels (1:1) provides a convenient cross-platform square format.

Since previews and crops can vary by device and post context, keep important information away from the outer edges.

Pinterest Image Sizes 2026

Pinterest differs from many social networks because tall vertical images are central to the platform's visual experience.

Pinterest Standard Pin Size

1000 × 1500 pixels (2:3).

This vertical ratio gives Pins enough space to communicate information without becoming excessively long.

Pinterest Profile Picture

Use a clear square image with the important content centered because profile pictures may be displayed in a circular format.

Pinterest Cover Image

800 × 450 pixels or larger provides a useful 16:9 starting point for a profile cover.

What Is the Best Universal Social Media Image Size?

There isn't one perfect image size for every placement, but a few dimensions cover a large percentage of everyday social media needs:

• 1080 × 1080 px (1:1) — square social posts.
• 1080 × 1350 px (4:5) — portrait feed posts.
• 1080 × 1920 px (9:16) — Stories, Reels, TikTok, and other full-screen vertical content.
• 1200 × 630 px — landscape and link-sharing graphics.
• 1280 × 720 px (16:9) — YouTube thumbnails and other widescreen graphics.

If you're creating one visual for several networks, 1080 × 1080 pixels remains a practical square starting point. However, creating platform-specific versions gives you more control over how the image appears.

Why Do Social Media Image Sizes Matter?

Using the correct dimensions isn't just about making a post look good. It can improve the overall presentation and consistency of your content.

1. Prevent Unwanted Cropping

Platforms may automatically crop images that don't fit the intended placement. Important text, logos, products, or people near the edges can disappear.

2. Maintain Image Quality

Uploading an image that is too small can result in a soft or pixelated appearance when the platform enlarges it.

3. Create Consistent Branding

Correctly sized visuals make profiles and campaigns look more intentional and professional.

4. Improve Mobile Presentation

Most social content is consumed on mobile devices. Vertical formats such as 4:5 and 9:16 make better use of limited mobile screen space.

Understanding Aspect Ratios

Image dimensions and aspect ratio are related, but they are not the same thing.

Dimensions describe the actual width and height in pixels. For example, 1080 × 1080 pixels.

Aspect ratio describes the proportional relationship between width and height.

• 1:1 — square
• 4:5 — portrait
• 9:16 — full-screen vertical
• 16:9 — widescreen landscape
• 2:3 — common vertical Pinterest format

Two images can have different pixel dimensions while sharing the same aspect ratio. For example, 1080 × 1920 and 720 × 1280 are both 9:16.

How to Resize an Image for Social Media

You don't need professional design software simply to change an image's dimensions.

1. Open the Doxvera Image Resizer.
2. Upload the image you want to resize.
3. Choose the required dimensions for your social platform.
4. Resize the image.
5. Download the finished version and use it in your post.

Before resizing, check the recommended dimensions in this guide and consider whether your original image will need cropping to fit a different aspect ratio.

JPG vs PNG: Which Is Better for Social Media?

Both JPG and PNG are widely used, but each format has different strengths.

Use JPG When:

• You're uploading photographs.
• You want a relatively small file size.
• The image contains many colors and gradients.

Use PNG When:

• Your graphic contains text or a logo.
• You need crisp edges in digital graphics.
• You need transparency where supported.

For most photographs, JPG is a practical choice. For logos, interface graphics, screenshots, and designs containing sharp text, PNG can be preferable.

Social Media Image Best Practices

Start With a High-Quality Source

Resizing a very small image to a much larger resolution cannot restore detail that isn't present in the original file. Start with the highest-quality source available.

Keep Important Content Away From the Edges

Profile pictures, grid previews, interface overlays, and responsive layouts can crop portions of an image. Leave breathing room around logos, faces, headlines, and calls to action.

Design for Mobile First

Always preview graphics at a smaller size. If a headline becomes difficult to read on a phone, make it larger or simplify the design.

Don't Stretch Images

Changing width and height without preserving the appropriate proportions can distort an image. Crop or resize according to the target aspect ratio instead.

Check Your Image Before Publishing

Platforms evolve and may display images differently across placements and devices. Preview important posts whenever possible before publishing them widely.
