Design and branding
Send us the best original files you have and we size everything for the platform. This guide lists each asset, the size we need and where it shows up on your event site. To click through a live example, open demo.jumbo.live.
Most event sites need only three things from you. Everything else is optional, and we use sensible defaults when it's missing.
A brand guidelines PDF and your logo files cover almost everything on this page. We pull what we need and ask about anything missing.

Nice to have
Attendees see your brand on the start page, where they enter their email to register or sign in, and on the event pages they land on afterwards. Hover over a number to see what it marks.
Each outline shows the asset's proportions. Sizes are minimums, and larger is always fine.
Vector original
Used in the header, on emails and in link previews. Vector files scale to any size without blurring.
600 pxwide or more
The horizontal version goes on the start and registration pages. The stacked or square version fills the logo card on your event pages. Without a separate event mark, we use your main logo.
720 × 1280px
Optional. Sits beside the email form and is cropped to fit each screen, so keep important details away from the edges.
1920 × 1080px
Optional. Sits behind the start page and the top of your event pages, softened so text stays readable. A solid color works well too. If you use an image, pick one that still works when it's cropped.
1200 × 627px exactly
The card that appears when someone shares your link in email, Teams, Slack or LinkedIn. More under Link previews.
1200 pxwide or more
Optional. It sits at the top of confirmation and reminder emails. Without one, we use your horizontal logo.
512 × 512px
Optional. The small icon in the browser tab. Use a simple mark that stays clear at 16 px.
1920 × 1080px
Optional. Thumbnails for the schedule and on-demand library, and any video you'd like on the site.
Interby default
Optional. Sites use Inter unless you'd like your own typeface. If you do, send the font files and confirm your license covers web use.
We list sizes in full pixels, and high-resolution screens show images at about half that size, so a 600 px image appears about 300 px wide. Send the original file even for small placements, so we have room to crop and resize cleanly.
Send hex codes for your brand colors and tell us which ones you use for buttons, links and headings. We apply them across the site and can override them for a single page or sponsor. Here's Jumbo's own palette as an example.
Body text needs a contrast ratio of at least 4.5 to 1 against its background to meet accessibility guidelines. Light brand colors often work better as accents than behind white button text. We flag any pairs that fall short.
| Asset | Best | Also fine |
|---|---|---|
| Logos and graphics | AI, EPS, PDF or SVG | PNG with a transparent background |
| Photos | JPG at full resolution | PNG |
| Icons | SVG | PNG, or we make them from your vector artwork |
| Video | The original export, 16:9, 1920 × 1080 or larger | A Vimeo link |
| Fonts | OTF or TTF, every weight you use | WOFF2 |
Put everything in one shared folder, such as Dropbox, Google Drive, SharePoint or Box, and send the link to your Jumbo Customer Success contact. Name files for what they are, like logo-white.svg or start-image.jpg, so nothing gets mixed up.
