About this tool
Listing & Ad Spec Checker
Check product images and captions against Amazon, Flipkart, Meesho, Etsy, Shopify, Facebook ad, Instagram caption and TikTok caption rules before you upload.
Pick the platform and check your image size, ratio and file or your caption length against its current rules. This page brings together 8 separate listing & ad spec checker pages (Amazon, Etsy, Facebook ad image, Flipkart, Instagram caption, Meesho, Shopify, TikTok caption) so you can compare them without hunting for the right one.
How to use Listing & Ad Spec Checker
- 1
Open Listing & Ad Spec Checker on AltFTool — it loads instantly in your browser.
- 2
Choose your platform at the top: Amazon, Etsy, Facebook ad image, Flipkart and 4 more. On a phone it is a drop-down list.
- 3
Fill in the listing & ad spec checker for that platform; each of the 8 options keeps its own rules, data and defaults.
- 4
Read the result, then switch platform to compare. The page link keeps your platform (?v=amazon), so you can bookmark or share it.
Why use Listing & Ad Spec Checker
All 8 in one place
Amazon, Etsy, Facebook ad image and the rest sit behind one picker, so switching platform takes a tap instead of a new search.
Built for each option
Every platform keeps its own rules, numbers and defaults rather than one generic template.
Shareable view
The link remembers the platform you picked, so a bookmark or a shared link opens straight on it.
Common use cases
- Find out why a 900 px product shot never shows the zoom cursor on the detail page.
- See how much of a square product photo the 4:3 search thumbnail cuts off before you list.
- Confirm a 1200 x 628 link image will run in both the feed and the right column before a launch.
- Check a supplier's product shot before a bulk catalogue upload so it is not rejected at QC.
Frequently asked questions
Which platform options does this tool cover?
8: Amazon, Etsy, Facebook ad image, Flipkart, Instagram caption, Meesho, Shopify, TikTok caption. Pick one at the top of the tool; the page link updates (for example ?v=amazon) so you can bookmark or share that exact view.
What size should Amazon product images be?
At least 1000 px on the longest side, because that is where Amazon enables the zoom viewer, and 1600 px or more is Amazon's own recommendation. Images below 500 px on the longest side are rejected, and the maximum is 10000 px.
What size should Etsy listing photos be?
At least 2000 pixels on the shortest side. Etsy lets buyers enlarge listing photos, so anything smaller goes soft the moment someone looks closely. Landscape photos around 3000 x 2250 px match the search thumbnail shape exactly and lose nothing to cropping.
What size should a Facebook ad image be?
1080 x 1080 px is the safest single size for feed placements — Meta recommends at least 1080 px on both sides and accepts ratios from 1.91:1 through 1:1, with a minimum of 600 x 600 px. Use 1080 x 1920 px at 9:16 for Stories and Reels, and 1080 x 1350 px at 4:5 for vertical feed.
What is the minimum image size for a Flipkart listing?
500 x 500 pixels. Flipkart recommends 1500 x 1500 px or larger, because the zoom viewer on the product page magnifies the file you upload and anything smaller looks soft when a buyer inspects the product.
What is the Instagram caption character limit?
2,200 characters, including spaces, emoji and hashtags. Anything longer is rejected rather than truncated, so a caption pasted from a document has to be cut before it will post. The visible portion in the feed is far shorter — around 125 characters before the "... more" link.
What size should a Meesho catalogue image be?
At least 500 x 500 pixels, with 1000 x 1000 pixels or larger recommended so the product stays sharp when a buyer zooms. Square framing is the standard because catalogue thumbnails are square; several apparel categories also accept a 3:4 portrait crop.
What is the best image size for Shopify products?
2048 x 2048 pixels for square product photos. That is Shopify's own recommendation: it is large enough for a sharp zoom on retina screens and comfortably under the 25 megapixel / 5000 px ceiling, and Shopify generates all the smaller variants automatically.
How many characters can a TikTok caption be?
2,200 characters. TikTok raised the caption field from 300 to 2,200 characters in 2022, and hashtags and @mentions are counted inside that same budget rather than added on top.
