Ecom Almanac is a working reference desk for online sellers: currency and country codes, image sizes, fee math and pre-launch checklists — in tables you can bookmark and trust.
All reference pages are dated and revised on a fixed schedule.
A working pre-launch checklist for a new online store: storefront, legal pages, payments, shipping, SEO basics, analytics and the tests to run before you announce anything.
What a store pays per order on each Shopify plan: subscription rates, processing formulas and an interactive calculator you can run with your own numbers.
The official Shopify limits for product photos, video and 3D models in one table: maximum pixels, file sizes and formats, straight from the Shopify Help Center.
The image dimensions a store actually posts in one table: feed posts, Reels, Stories, pins and link previews, checked against each platform's official documentation.
Every active ISO 4217 currency in one table: alphabetic code, numeric code and currency name, for checkout settings, product feeds and payment APIs.
