Logo Handoff for Developers: Assets, Sizes, and Tokens

You’re wrapping up a branding project. The logo is polished, the client is thrilled, and now it’s time to hand everything over to the developers. But wait — what exactly do they need? And how do you hand over a logo in a way that makes sense for dev work? Let’s break it all down so your amazing design shines, pixel-perfect, in the final product.

TL;DR

When handing off logos to developers, include organized assets in multiple sizes and formats. Offer design tokens that specify spacing, colors, and typography. Keep assets clear, named consistently, and include guidelines. Make it as easy as possible for devs to plug your design directly into code.

Why Logo Handoff Matters

Designers love precision. Developers love logic. If your assets are messy, the devs will either guess (uh-oh) or come calling. A good handoff saves time, money, and frustration on both ends.

Think of handoff like delivering pizza. If you drop it off in a crumpled box, with three missing slices and no napkins, no one’s happy. But if it’s neatly packed, labeled, and hot — that’s gold!

What to Include in a Logo Handoff

Let’s start with the basics. These are your non-negotiables.

• Logo files: Always provide multiple file types (SVG, PNG, PDF, EPS).
• Sizes and scales: Include different sizes optimized for web, mobile, and app icons.
• Colors: Provide HEX, RGB, CMYK, and Pantone values.
• Spacing rules: Indicate how much empty space should surround the logo.
• Do’s and Don’ts: Show correct and incorrect logo use — devs need this too!

The more you include, the fewer questions devs will ask later. And that, friend, is a win.

Logo File Formats Demystified

Different formats serve different needs. Here’s what developers usually look for:

• SVG: Ideal for web. Scalable, lightweight, perfect for CSS manipulation.
• PNG: Good for raster fallback. Use 2x or 3x resolution for Retina displays.
• PDF: Great for internal use or documentation.
• EPS: Mainly for print or if devs are working with legacy tools.

Make sure they’re exported cleanly. No weird layers. No hidden elements. Just the logo, clean and sharp as a samurai sword.

How Big Is Big Enough?

Developers don’t just need one size. They need a friendly family of logo sizes for everything from navbars to favicons.

Here’s a helpful list of common sizes to include:

• 16×16 (favicon)
• 32×32 (web icon)
• 64×64 (compact UI spots)
• 128×128
• 256×256
• 512×512 (app store or splash screen)

Pro tip: Keep all these in a folder named something like “Logo Sizes” and label each file clearly. Developers will treat you like royalty.

Design Tokens: A Dev’s Best Friend

This sounds fancy, but it’s really just a smart way of turning design decisions into code-friendly values.

Design tokens are variables that define things like:

• Logo colors
• Padding
• Background shapes
• Font choices (if the logo includes text)

Here’s an example of some design tokens you might hand over:

{
  "logoColorPrimary": "#1A1A1A",
  "logoColorAccent": "#FF9900",
  "logoSpacing": "24px",
  "logoFont": "Roboto, sans-serif"
}

By using tokens, developers can keep things consistent across the app. If the color changes later? Update the token, and it updates everywhere. Magic!

Folder Structure for Handoff

Structure matters. A wild, chaotic zip folder makes devs cry.

Here’s a simple, joyful structure to follow:

Logo-Handoff/
├── src/
│   ├── logo-original.ai
│   ├── logo.svg
│   ├── logo-dark.svg
│   └── logo-light.svg
├── sizes/
│   ├── logo-16x16.png
│   ├── logo-32x32.png
│   └── logo-256x256.png
├── docs/
│   ├── logo-guidelines.pdf
│   └── color-tokens.json

It’s clean. It’s neat. It’s easy to navigate. Perfection.

How to Describe Spacing and Alignment

Linear spacing. Padding. Margins. Sounds boring, right?

Not for developers.

If your logo needs white space around it — say 20px minimum — that’s gotta be in your handoff. Show it in a diagram with labeled margins. Or write it like this:

• Logo must have 20px minimum top, bottom, left, and right spacing.
• Align logo to container center horizontally and vertically.

Clarity rules. Ambiguity drools.

Color Specs

Never leave developers to guess your brand colors. Give them:

• HEX codes (for web)
• RGB (for older browsers or niche needs)
• CMYK (for any printed use)
• Pantone (for merch, packaging, etc.)

And name the colors! Like:

Brand Navy - HEX: #001F3F
Accent Yellow - HEX: #FFDC00

Names help big time when working across teams.

Logo Dos and Don’ts

Sometimes, the best way to explain usage is to show what not to do. Yes, even to developers.

Create a simple graphic that shows:

• Do: Use the logo on white or branded backgrounds.
• Don’t: Stretch, recolor, or add drop shadows.
• Do: Follow spacing guidelines.
• Don’t: Place the logo on busy images without contrast.

This isn’t being fussy. It’s guarding your brand’s soul.

Working With Light and Dark Modes

Modern interfaces often switch between light and dark modes. Make sure your logo comes in at least two versions:

• One for light backgrounds (usually darker logo)
• One for dark backgrounds (usually lighter logo)

Use names like logo-light.svg and logo-dark.svg. Devs love that kind of clarity.

Optional Bonus: Animations or Loaders

If your brand uses an animated logo in intros or splash screens, go the extra mile. Include:

• MP4 version
• Web-optimized GIF
• JSON or Lottie files (if the app uses Lottie format)

Ask the client or devs first, though. They might not need it — or they might love that you thought to include it.

Final Checklist

Before you hit send, go through this final list:

• • ✔ All file types exported (SVG, PNG, etc.)
  • ✔ Logo versions for light and dark modes
  • ✔ Color values in usable formats
  • ✔ Spacing and size rules clearly documented
  • ✔ Do’s and don’ts visual guide included
