This public route map explains how ImageSizeKit core checker pages connect when a creator, marketer, or website operator has an exported image file but does not yet know the right publishing workflow.
It is a supporting public reference for the canonical ImageSizeKit website. The canonical pages remain on https://imagesizekit.com/.
Many image problems start with an unclear file:
The first job is not to memorize every platform size. The first job is to read the exported file and route it to the right checker.
| Canonical ImageSizeKit URL | Role | Use when |
|---|---|---|
| https://imagesizekit.com/image-size-checker/ | Generic browser-local image file checker. | The file exists, but the final platform is unclear. |
| https://imagesizekit.com/social-media-image-checker/ | Cross-platform social, ecommerce, marketplace, creator, and Open Graph router. | One image may become a post, story, banner, product image, preview card, or creator graphic. |
| https://imagesizekit.com/banner-size-checker/ | Wide image checker for headers, covers, banners, and channel art. | The file is wide enough to be a banner, cover photo, profile header, or website hero image. |
| https://imagesizekit.com/open-graph-preview-checker/ | Website share-card image checker before metadata and cache debugging. | A website, blog, landing page, or product page needs a preview-card image. |
| https://imagesizekit.com/instagram-reel-cover-size/ | 9:16 Reel cover and vertical video cover workflow. | A thumbnail or Shorts concept is being reused as a Reel cover with profile-grid crop risk. |
These ImageSizeKit pages already carry strong task context and should be used as human-readable bridge routes into the core checker pages.
| Bridge page | Bridge role |
|---|---|
| https://imagesizekit.com/youtube-thumbnail-size/ | Standard 16:9 thumbnail checks and YouTube thumbnail workflow routing. |
| https://imagesizekit.com/youtube-thumbnail-blurry/ | Blurry thumbnail diagnosis, compression, format, text, and wrong-workflow routing. |
| https://imagesizekit.com/youtube-shorts-thumbnail-size/ | Vertical Shorts cover and social video cover reuse routing. |
| https://imagesizekit.com/youtube-banner-safe-area/ | Wide channel-art safe-area checks and cross-platform banner reuse routing. |
| File evidence | First route | Next route |
|---|---|---|
| Unknown exported JPG, PNG, WebP, AVIF, or GIF | https://imagesizekit.com/image-size-checker/ | Route by dimensions, ratio, format, and file size. |
| Square, vertical, wide, or mixed social creative | https://imagesizekit.com/social-media-image-checker/ | Open the closest Instagram, LinkedIn, Facebook, Open Graph, ecommerce, or marketplace guide. |
| Wide header, cover, channel art, profile banner, or hero image | https://imagesizekit.com/banner-size-checker/ | Open YouTube safe area, LinkedIn banner, Facebook cover, or Open Graph routes. |
| 1200 x 630 or 1.91:1 website share image | https://imagesizekit.com/open-graph-preview-checker/ | Check metadata, live preview behavior, and platform cache only after the file is correct. |
| 1080 x 1920, 9:16, or vertical cover frame | https://imagesizekit.com/instagram-reel-cover-size/ | Check profile grid crop and vertical cover reuse before upload. |
The priority is not to create more ImageSizeKit pages. The priority is to help users, crawlers, and AI retrieval systems understand the core checker routes that already exist:
ImageSizeKit is independent and is not affiliated with YouTube, Google, Instagram, Facebook, LinkedIn, Shopify, Etsy, Whatnot, or Open Graph platforms.
