The short answer
The right logo size for Squarespace is less a fixed pixel count than a well-prepared image. Squarespace shows the header logo at a size set in the site's header or style settings, so the uploaded file mainly needs three things: enough resolution to stay crisp at its largest displayed size, a shape that suits your header, and no excess empty space around the artwork. The best way to produce that file is to export it from a master vector logo rather than enlarge an existing small image.
No confirmed figures were available for this article, so it gives no specific dimensions, file-size limits or format lists. Squarespace's recommendations can change between platform versions and templates. Check its current help documentation for exact values, and confirm the result in the editor's desktop and mobile previews.
Display size and file size are different things
There are two sizes to think about. The file size is the pixel dimensions of the image you upload. The display size is how large the logo appears on the page, which is controlled by the site's header settings, typically as a logo height. Squarespace scales the uploaded image to fit that setting, so uploading a larger file does not by itself make the logo appear bigger. It gives the browser more detail to work with when it draws the logo at the chosen size.
Because the display size is usually set by height, the logo's proportions matter. A wide horizontal lockup set to a given height takes up much more of the header's width than a square symbol does. A tall, stacked logo can look small and hard to read. If your logo exists in several versions, the horizontal one is often the most practical choice for a site header. That is a general layout judgment, and your template and navigation may change it.
Why resolution matters on high-density screens
Many phones, tablets and laptops have high-density displays that use more than one physical pixel for each layout pixel. A logo exported at exactly its on-screen size can look soft on these screens. A common practice is to export the image at a multiple of the largest size it will be displayed at, so there is spare detail. The trade-off is file weight: very large images slow the page down without adding visible sharpness. Aim for enough resolution to cover high-density screens, then compress the file sensibly.
Minimum legible size: design for the smallest view
The real constraint is usually the smallest size at which the logo appears, not the largest. Headers often shrink on mobile layouts, and a logo that reads well on desktop can become illegible on a phone. Common problems at small sizes include the following:
- Thin strokes and hairline details that blur or disappear.
- Taglines and small secondary text that can no longer be read.
- Tight letter spacing or narrow counters (the enclosed spaces in letters) that fill in visually.
- Low-contrast colors that blend into the header background.
If the full logo fails in the mobile preview, use a simplified version for the header. Options include dropping the tagline or using a compact lockup. Squarespace's options for setting a separate mobile logo depend on the version and template, so check what your site's header settings allow. Legibility at small sizes is a visual judgment, so test it on actual devices as well as in the editor preview.
Trim the canvas so padding doesn't shrink the logo
Squarespace scales the whole image, including any empty margin around the artwork. If the exported file has a wide transparent border, the visible logo appears smaller than the height setting suggests. It can also look off-center next to the navigation. Before exporting, crop the artboard or canvas closely to the artwork's edges. Leave only the minimal clear space your brand guidelines call for.
Vector master, raster delivery
Treat the vector logo as the master and the web file as an export. A vector file defines shapes as paths, so it can be scaled to any size without losing quality. Web headers commonly use raster files such as PNG, which store a fixed grid of pixels. Exporting from the vector master at the resolution you need gives a cleaner result than enlarging a small raster image, which cannot recover detail that was never there.
Which file formats Squarespace accepts for the logo, including whether SVG is supported in your version, should be checked against its current documentation rather than assumed. A PNG with a transparent background is a widely used choice because it sits cleanly on colored or image headers. If your header background varies, check the logo against each background it will appear on.
A file extension does not guarantee editable vector paths. A file saved as SVG, EPS, PDF or AI may contain an embedded raster image, or a low-resolution preview, rather than true paths. Open the file in a vector editor and confirm that the shapes are selectable paths before relying on it as a scalable source. If the logo uses live text, convert it to outlines in the export copy, or make sure the font is available. Otherwise the type may change when the file is opened elsewhere.
Other logo assets on a Squarespace site
The header logo is not the only branded image a site uses. Each asset has its own shape and purpose, and one file rarely suits all of them.
| Asset | Where it appears | Shape to plan for | What to check |
| Header logo | Site header on desktop and mobile | Usually horizontal; follows your lockup | Legibility at the smallest header size, trimmed padding, contrast with the header background |
| Browser icon (favicon) | Browser tabs and bookmarks | Square | Whether a simplified symbol reads at very small sizes; a full wordmark usually will not |
| Social sharing image | Link previews on social platforms | Set by the platform and Squarespace settings | Current recommended dimensions in Squarespace's documentation and how the preview crops the image |
A practical preparation workflow
- Start from the master vector file and confirm it contains real paths, not an embedded image.
- Pick the lockup that suits a header, usually a horizontal version, and decide whether you also need a simplified version for small screens.
- Crop the artboard tightly to the artwork, leaving only the minimum clear space.
- Export a transparent PNG, or another format your Squarespace version accepts, at a multiple of the largest display size for high-density screens.
- Compress the file so it stays sharp without being unnecessarily heavy.
- Upload it, set the logo height in the header settings, and review desktop and mobile previews.
- Check the result on real devices and against every header background the logo will sit on.
Rights and permissions
Preparing a logo for your own site assumes you have the right to use and adapt it. Being able to download a logo file does not grant permission to modify the artwork or to use the fonts or trademark it contains. If the logo came from a designer, a template or a third party, check the license or agreement before changing it or creating simplified variants.
What this article could not confirm
Without supplied evidence, this article does not state Squarespace's recommended pixel dimensions, maximum upload sizes, accepted formats or version-specific header options. These details are set by Squarespace and may differ between template families and over time. Verify them in Squarespace's current help documentation and in your site's settings, and make the final call based on how the logo actually looks in the preview.
