Email Template Placeholder Images — All Sizes

Email templates require images at specific pixel widths to render correctly across Gmail, Outlook, Apple Mail, and mobile clients. The Email Template preset generates correctly sized placeholders for every common email slot — header, hero, product card, and banner — so you can build and test layouts before real photography is available.

Size reference

NameDimensionsDescription
header600x200Email header — 600×200, the top branding strip in a standard single-column email
hero600x400Hero image — 600×400, the main promotional image below the header

banner600x100Footer banner — 600×100, a slim promotional or legal strip at the bottom of the email

Why these sizes matter

Email clients do not scale images the way browsers do. Outlook ignores CSS width declarations on images in some configurations, causing oversized renders. The industry-standard email container is 600px wide, making 600-wide images the safe default for header, hero, and banner slots. Product card images inside multi-column layouts need to fit within each column — typically 280px in a two-column 600px layout. Getting image dimensions right at the design stage prevents broken layouts in production.

Use cases

Email template development

Build HTML email templates with correctly sized placeholder images so the layout renders accurately in all email clients before real photography is sourced.

ESP campaign previews

Upload placeholder images to Mailchimp, Klaviyo, or HubSpot to preview campaign layouts and check rendering across devices before the final send.

QA and screenshot testing

Use committed placeholder images as stable fixtures for email screenshot comparison tools like Litmus or Email on Acid so visual diffs catch real layout changes.

FAQ — Frequently asked questions

Why is 600px the standard email width?
600px is the widely accepted safe width for HTML emails because it renders correctly in the most common email clients without horizontal scrolling on desktop or aggressive mobile scaling. Some modern campaigns use 640px, but 600px has the broadest compatibility.
Can I use these images in Mailchimp or Klaviyo?
Yes. Download the PNG ZIP, then upload the images to your ESP's media library or embed them as local assets in your template. Placeholder images are useful during the design and QA phase before real photography is ready.
What size should a product card image be in a two-column email?
In a standard 600px email with two equal columns, each column is 280px wide after accounting for padding. A 280×280 square image fills the column slot without scaling issues across email clients.
