WhatsApp/Telegram Post Size 2026: Official Measurements and Complete Dimension Guide
Why Creative Size Matters on WhatsApp and Telegram
In WhatsApp groups and Telegram channels, people scan quickly. The image needs to load fast, show the product clearly and make the price easy to read on a small screen. If the banner is cropped, heavy or cluttered, the offer loses attention before the click.

The questions our community asks the most
The same questions reach our community every week. Here they are, with short answers and no filler.
How do I post to many groups at once?
By organising your offer catalogue and schedule in one place: you set the times and the system publishes to every connected group and channel. That is what keeps dozens of channels active without copy-pasting all day.
Which affiliate program is best to start with?
Start with the store your audience already buys from: fashion audiences fit Shein and Shopee, tech audiences fit Amazon, AliExpress and Mercado Livre. Once you have rhythm, add a digital product for the higher commission per sale.
How do I become an affiliate?
Pick a program, register for free, list where you will promote and wait for approval, which usually takes one to two days.
