Brand Style Guide: What to Ask Your Designer For

Most founders do not get a weak style guide because they hired the wrong designer. They get one because they asked for too little, too late. I have seen this pattern again and again in my own work: a seller launches with a nice logo, then every new listing, box, and social post drifts a little further from it. Six months later, nothing matches, and nobody can say what the brand was supposed to look like in the first place.

A style guide is not a luxury document for big companies. It is the instruction sheet that stops that drift. If you are paying for design, ask for the guide up front, while the designer still remembers every choice they made and why they made it.

Start with the files, not the feelings

The bottom line is simple: if you cannot open, reuse, and hand over the files, you do not own a brand system, you own a picture. Ask for the primary logo, a stacked version, a horizontal version, a one-color version, and a reversed version for dark backgrounds. Ask for each one as a vector file and as a high-resolution PNG with a transparent background. A JPG on a white box is not a logo system, it is a screenshot of one.

Ask for the same treatment for any icon, badge, or pattern your designer creates. I always tell sellers to test the files the day they receive them. Put the logo on a listing image, on a box mockup, and on a dark banner. If it breaks in any of those places, send it back before you approve the final delivery. That ten minute test saves weeks of awkward fixes later, and it is the same discipline I recommend when you brief a listing image designer with a clear template instead of a vague idea.

Also ask, in writing, who owns the source files. You should receive the editable originals, not only the exports. If a designer keeps the source files hostage, every future change costs you a new negotiation. Ownership is not a rude question. It is a normal part of a professional handover.

Colors and fonts need rules, not names

The bottom line here is that a color name is not a color rule. Ask for exact values: HEX for screens, CMYK for print, and RGB where your designer works in that space. Ask for a primary color, two or three supporting colors, and a neutral set for backgrounds and text. Then ask for the ratio: which color leads, which one supports, and which one is only for small accents and calls to action.

Fonts need the same discipline. Ask for one headline font and one body font, with sizes and weights for the main uses: listing headlines, infographics, packaging, and A+ modules. Ask which font replaces each one if the original is not available on a given platform. Without that fallback, a teammate will pick something close enough, and close enough is how a brand slowly stops looking like itself.

This matters because shoppers judge fast. In Salsify's 2025 consumer research, 77% of shoppers said high-quality images and videos are important to their purchase decisions. That judgment starts with color and type. A listing that uses three different blues and two different headline fonts does not look creative. It looks unfinished, and shoppers read unfinished as risky.

Tone is a decision, not a vibe

The bottom line is that tone must be written down, or every writer and designer will invent their own version of it. Ask your designer to describe the brand voice in plain words: friendly or formal, playful or serious, premium or practical. Then ask for three example sentences in that voice, and three sentences that would never appear under your brand name.

Ask for image tone rules in the same way. Do your photos look bright and airy, or warm and moody? Are people smiling at the camera, or using the product naturally without posing? Is the background clean studio white, or a real kitchen, bathroom, or living room? These choices are not decoration. They tell a shopper who the product is for before a single bullet point is read.

I like to ask sellers one test question: could a stranger pick your listing out of a search page without reading the brand name? If the answer is no, the tone rules are too vague. A good guide makes that test easy, because color, type, photography, and wording all point in the same direction. That consistency is also why a brand and apparel graphics system should be planned as one set of rules, not as separate one-off designs.

Sizes and formats save the redesign later

The bottom line is that a guide that only works at one size will fail everywhere else. Ask for minimum sizes: how small can the logo go before it becomes unreadable, and what version should replace it at that size? Ask for clear space rules: how much empty space must sit around the logo so it never crowds against text or an edge.

Ask for the Amazon rules to be built in, not added later. Amazon requires the main image background to be pure white, RGB 255, 255, 255, with the product filling at least 85% of the frame, as set out in Amazon's main image requirements. A style guide that ignores that rule will produce beautiful art that Amazon suppresses. Your designer should show you how the brand survives inside those limits: which colors, fonts, and layouts still read clearly when the image is a small thumbnail on a phone.

Ask for packaging rules in the same document. A guide that covers screens but not boxes creates a second brand by accident. I have written before that packaging is a billboard, not a brochure, and the guide is where that idea becomes practical: one headline, one promise, and the same colors and fonts a shopper just saw online. When the box arrives and matches the listing, trust goes up. When it does not, the shopper wonders if they bought the right product.

Ownership, updates, and the handover checklist

The bottom line is that a guide is only useful if someone keeps it current. Ask for a one-page handover sheet: file locations, font names and licenses, color values, and the name of the person who can approve a change. Ask how future products fit in: do new colors get added, or does every product use the same palette with a different accent?

Use this checklist before you sign off. Logo versions in vector and PNG, color values for screen and print, headline and body fonts with fallbacks, tone examples with do and do not lines, photography style rules, minimum sizes and clear space, Amazon main image compliance, packaging rules, and full source file ownership. If any item is missing, ask for it now. It is far cheaper to add a page to a guide than to rebuild a brand after a year of drift.

Amazon puts it well in its own leadership principles: "Leaders start with the customer and work backwards. They work vigorously to earn and keep customer trust. Although leaders pay attention to competitors, they obsess over customers." That is what a style guide really is, in my view. It is working backwards from the shopper's trust, and writing down every choice that earns it. You can read the full principle at Amazon's Customer Obsession principle.

If you already have a guide and it feels thin, do not throw it away. Audit it against the checklist above, fill the gaps one page at a time, and check whether your current listings still match it. I have covered when to redesign your Amazon listing images, and the same test applies here: if the guide no longer describes what shoppers actually see, it is time to update the guide first, then the assets.
