Logo guidelines should answer one question: how does the logo get used correctly by someone who did not design it? At minimum, that means the primary mark and its approved variants, clear space, a minimum size, the approved colors and backgrounds, and a short list of what never happens to the logo. Most brands collect the logo files first and write the rules last, if they write them at all. A sales deck still carries last year's logo, or a vendor stretches the mark to fill a banner, because nobody wrote down the rule that would have stopped it. If you are starting the whole document from scratch, a brand guidelines template covers the rest of the guide. This post covers what belongs in the logo section specifically, and where to put it so people check before they use the logo, not after.
Key Takeaways
- Logo guidelines need the primary mark, every approved variant (horizontal, stacked, mark-only), clear space, and a minimum size stated in both pixels and inches.
- Approved colors and backgrounds matter as much as the file itself; a dark logo on a dark photo is a common misuse even when the file is the right one.
- A short, specific list of what never happens to the logo (no stretching, no recoloring, no shadows) stops more mistakes than a page about brand values.
- Guidelines only work if people check them before they use the logo. That is a problem of where they live, not how carefully they are written.
- TrueKeep keeps the guide next to the asset files in one portal, so the rule and the correct file sit on the same page.
What belongs in logo guidelines
Logo guidelines are the part of a brand guide that governs one asset: the logo. A complete section names five things: the primary mark and its variants, clear space, minimum size, approved colors and backgrounds, and what never happens to the logo. Leave one out and someone will eventually guess, and the guess usually becomes the exception everyone copies.
Each of the five earns its own section below, with enough detail that a designer or a vendor can act on it without asking anyone first.
The primary mark and its approved variants
The primary mark is the logo as the brand prefers it shown: the full lockup, at full color, on its cleared background. Most brands also need a horizontal lockup for wide spaces, a stacked version for square ones, and a mark-only icon for a favicon or an app tile.
Name each variant and state when it applies, rather than leaving the choice to whoever opens the asset folder. "Use the stacked version below 300 pixels wide" is a rule. "Use whichever one fits" is not.
Clear space and minimum size
Clear space is the empty margin the logo keeps from text, edges, and other graphics, usually stated as a multiple of a fixed unit inside the mark itself. A common rule: clear space on every side equals the height of the icon, so the logo never touches another design element.
Minimum size states the smallest the logo can print or render before it loses detail, typically given in pixels for screen and inches for print. A mark that reads fine at 100 pixels can turn into a smear at 16, so write the floor down rather than let someone find it by accident. The 1976 NASA Graphics Standards Manual, reissued today by Standards Manual, is still held up as one of the strictest logo guides ever written, down to the exact placement on a launch vehicle.
Approved colors and backgrounds
Most logos need at least three color versions: full color for light, uncluttered backgrounds; a single dark color for light photos; and white for dark backgrounds and photos. State which version goes with which kind of background, not just which colors exist.
Contrast is the real rule here. A navy logo on a navy folder cover is technically the right file and still wrong, because nobody can read it.
What never happens to the logo
A short list of prohibitions does more work than a page of brand philosophy. The common ones: never stretch or squeeze the mark to fit a shape, never recolor it outside the approved versions, never add a drop shadow, outline, or glow, never rotate it, and never place it on a background that fails the contrast rule above.
Write each one as a rule, not a paragraph. A vendor skimming a brief will catch "never stretch the logo" and miss the same point buried in a sentence about brand integrity. The design blog Brand New has covered plenty of rebrands where the new mark was misapplied within weeks of launch, usually in exactly these ways. There is a legal reason to keep the list strict, too: the International Trademark Association notes that inconsistent use of a mark can weaken the legal protection built on consistent use.
Where logo guidelines live, so people actually check them
A rule nobody finds in time does not get followed. The guidelines do the least good sitting in a PDF from two redesigns ago, in a shared drive next to a dozen old exports. TrueKeep keeps the guide and the logo files in the same portal, across the four parts of the portal (strategy, guide, assets, and components), so a designer can read the clear-space rule and download the correct file in the same visit.
The design brief writes down the decisions behind the rules, kept current, and connected AI tools read that brief through the MCP connection before they draft anything. The same colors and backgrounds that stop a designer from misusing the logo also sit in front of whatever tool writes the next caption or deck. Edit mode lets whoever owns the brand update the guide directly when a rule changes, which matters because a portal only helps as long as someone keeps it current. Name that person before launch, not after the first exception.
Frequently asked questions
What should logo usage guidelines include? Logo usage guidelines should include the primary mark and its approved variants, clear space, minimum size, approved colors and backgrounds, and a short list of what never happens to the logo. Anything less leaves a gap someone will eventually fill with a guess.
How much clear space should a logo have? Most brands set clear space as a multiple of a fixed unit inside the mark, often the height of the icon or a letterform, kept on all four sides. The exact multiple matters less than stating one number and applying it everywhere the logo appears.
What is the minimum size for a logo? A minimum size states the smallest the logo can appear before its detail breaks down, usually given in pixels for screens and inches for print. Below that size, swap to the mark-only variant instead of shrinking the full lockup further.
Can a logo be recolored for a campaign? Only if a recolored version appears in the approved colors section. Otherwise, no. Campaign-specific colors belong on the page or the banner around the logo, not inside the mark itself.
Where should a company keep its logo guidelines? Next to the logo files themselves, in whatever place a designer or a vendor already checks before starting work. Guidelines kept in a separate document from the assets tend to go unread, because checking two places costs more than guessing.
Do AI tools need logo guidelines too? Increasingly, yes. A tool drafting a deck or a social caption works from whatever brand rules it can read, so the same clear space and color rules written for a designer should reach a connected AI tool before it writes anything.
Conclusion
The primary mark and its variants, clear space, minimum size, approved colors and backgrounds, and what never happens to the logo: that is the whole list for logo guidelines. Write each one so a designer or a vendor can follow it without checking with anyone. State the rule, not the reasoning, and put it where the files already live.
The harder part is not writing the guidelines once. It is keeping them next to the assets so people check them before they use the logo, and keeping someone in charge of updating both when the brand changes. Get started to put the guide and the logo files in one portal.
