Choose the right logo dimensions

There is no single correct size for a logo. A true vector logo can be scaled up or down without losing quality, so choosing dimensions is mostly about two decisions. First, keep the artwork's proportions intact. Second, set the canvas, and the pixel or physical size of any export, to suit the place where the logo will appear. If the destination needs a different shape or more breathing room, expand the canvas around the logo rather than stretching or cropping the mark.

What "logo size" means for a vector file

Vector artwork is built from paths that are described mathematically rather than as a grid of pixels. Because of that, the artwork has no fixed resolution. A vector logo file still has measurable dimensions, though. These come from the canvas (often called the artboard or document bounds) and from the size you choose when you export it. The artwork's own bounding box and the canvas around it are separate things, and you can change either one.

• Artwork proportions: the width-to-height ratio of the mark itself, which should stay fixed.
• Canvas dimensions: the area around the artwork that defines what gets exported, including any padding or clear space.
• Output size: pixel dimensions for screen and raster files, or physical dimensions for print.

Confirm the artwork is actually vector

A file extension alone does not prove that a logo contains editable vector paths. SVG, PDF, EPS and native design-app files can all hold embedded raster images, and some contain only a raster preview. Open the file in a vector editor and check it. Use an outline or wireframe view, select individual shapes, and look for placed or embedded images. Embedded raster parts will blur or pixelate when enlarged. A file that is only a raster preview gives you no paths to edit, so resizing it works like resizing any bitmap.

Keep the proportions fixed

Always scale a logo uniformly. Stretching it horizontally or vertically distorts letterforms and shapes and makes the mark look wrong. Sometimes the destination has a different shape from the logo, such as a square avatar slot for a wide wordmark or a wide banner for a compact symbol. In that case, change the canvas, not the logo.

Expanding the canvas instead of resizing the logo

Canvas expansion adds space around the artwork without altering the artwork itself. Use it to fit a required aspect ratio, to add clear space so the logo isn't cramped or cropped, or to place the mark consistently inside a fixed frame.

• Check any brand guidelines for required clear space, minimum size and approved logo variants.
• Decide the target shape and size from the destination's current requirements.
• Enlarge the canvas or artboard to that shape, leaving the artwork untouched.
• Center or align the logo as the layout requires, scaling it uniformly only if needed.
• Decide whether the added area should be transparent or filled with a background color.
• Export at the required output size and format, then check the result at its real display size.

In a raster image, expanding the canvas adds pixels around the edges but no detail to the logo itself. If a raster logo is too small for its new use, a larger canvas will not fix that. You need a larger export from the vector source.

Match dimensions to where the logo will appear

Use | What drives the dimensions | What to check

Websites and apps | The layout slot and the range of screen pixel densities | Use SVG where the platform supports it; otherwise export raster files large enough for high-density screens

Social profiles and platform uploads | Each platform's current upload specs and cropping, which is often square or circular | Check the platform's current documentation, then pad the canvas so no part of the mark is cut off

Favicons and app icons | Very small display sizes | Test legibility at actual size; a simplified mark may be needed

Print materials | The physical size and the printer's resolution requirements | Supply vector files where accepted and confirm requirements with the print provider

Signage and large-format output | Large physical dimensions | Use vector artwork and confirm that no embedded raster elements will be enlarged

Small sizes: legibility and minimum size

Scaling down can be harder than scaling up. Thin strokes, fine detail and small taglines may disappear or blur at small sizes, even in a perfect vector file. Many brand guidelines set a minimum reproduction size or provide a simplified variant for small uses. Preview the logo at the size it will actually be displayed rather than judging it zoomed in.

Exporting raster versions

Raster formats such as PNG and JPEG have fixed pixel dimensions. Export each one from the vector source at the size you need instead of enlarging an existing small raster file. For print, the pixel dimensions you need equal the physical size multiplied by the resolution the printer asks for, so get that resolution from the print provider. PNG supports transparent backgrounds and JPEG does not, which matters if you expanded the canvas with a transparent area.

Permission to edit is separate from permission to download

Being able to download a logo does not mean you may modify it. Changing its proportions, recoloring it, adding padding, or using its fonts and trademarks may each be restricted. Check the brand guidelines or license terms that apply. Some owners allow placement changes such as added clear space while prohibiting any change to the mark itself.

What this guide does not specify

No verified platform-specific pixel dimensions, print resolution figures or software-version details were available for this article. Upload specs, cropping behavior, format support and canvas-editing tools vary by platform and by software version. Confirm them in the current documentation for the platform, printer or editor you are using.
