SM Logo Design for Favicons: Choosing a Monogram Symbol That Works at Tiny Sizes
How to turn an SM monogram into a favicon: what the mark should be, how to simplify it for small sizes, and how vector masters differ from raster exports.
Contents
The short answer
An SM logo designed for favicon use is a monogram built from the letters S and M. It is drawn as a vector mark and then simplified so that it stays recognizable in a browser tab, a bookmark list or a home-screen shortcut. The goal is not to shrink a full logo. It is to choose or redraw a compact symbol that still reads as SM, or at least as the brand, when only a small grid of pixels is available.
No specific SM logo, brand, designer or product was identified in the material behind this article. What follows treats the SM monogram as a design concept. It covers general, verifiable principles of favicon symbol selection rather than any particular existing mark. Prices, timelines and the details of individual designs are outside what can be confirmed here.
How a favicon monogram differs from the main SM logo
A primary logo can rely on a wordmark, a tagline, fine strokes or subtle spacing, because it is usually shown at comfortable sizes. A favicon has much less room. Detail that looks refined on a website header can blur into a smudge at tab size. For that reason, the favicon version of an SM logo is often a separate, purpose-built variant of the brand identity rather than a scaled-down copy.
- Fewer elements: usually just the two letters or a single merged glyph, with taglines, outlines and secondary shapes removed.
- Heavier strokes: thin hairlines and delicate serifs tend to disappear, so stroke weight is often increased.
- Simpler counters: the open spaces inside and between letters need to stay open, or the letters merge visually.
- Strong contrast: the mark must separate clearly from its background in both light and dark browser interfaces.
- A fitted silhouette: the overall shape should use the roughly square favicon area well, without leaving the letters tiny inside empty space.
Selecting the symbol: monogram options for S and M
Several structural approaches are common when building a two-letter monogram. Which one suits an SM favicon depends on the brand's existing identity and on how well each version survives reduction. The judgments below are editorial and not measured results. Testing any candidate at actual favicon size is the only reliable way to choose.
| Approach | How it works for S and M | Favicon consideration |
| Side by side | S and M placed next to each other as separate letters | Easy to read at larger sizes, but two letters in a small square can each become very narrow |
| Stacked | One letter above the other | Can fill a square shape, but each letter gets only half the height |
| Interlocked or ligature | Strokes of S and M share or overlap parts | Can produce a compact, distinctive shape, but overlaps may fill in and lose legibility |
| Enclosed | Letters set inside a circle, square or badge shape | The container helps the icon stand out, but it takes space away from the letters |
| Single initial | Only S or only M is used for the favicon | Often the most legible choice at the smallest sizes, at the cost of showing only part of the monogram |
The S curve and the angular, repeated strokes of the M contrast well in shape, which can help a combined mark stay distinctive. The same contrast creates a risk. Where a curve meets several vertical strokes, the spaces between them can close up at low resolution. Designers often adjust stroke widths and gaps specifically for the favicon variant, rather than accepting the proportions of the full logo.
Vector master, embedded raster and raster previews
An SM favicon should start as true vector artwork: shapes defined by editable paths that can be adjusted and exported cleanly at any size. This matters because favicons are delivered in several forms, and each one should come from the same master rather than from repeatedly resized bitmaps.
- Vector artwork: editable paths and shapes, typically kept in a design source file or exported as SVG. This is the master that stroke weights and spacing are refined in.
- Embedded raster: a bitmap image placed inside a vector-format file. The file may carry a vector extension, but the SM letters inside it are still pixels and cannot be cleanly edited or scaled.
- Raster previews and exports: PNG or ICO images generated at fixed pixel sizes for browsers and devices. They are outputs, not editable sources.
A filename or extension alone does not prove a file contains editable vector paths. An SVG or other vector-format file can wrap a pasted bitmap, and a monogram set in a live font may depend on that font being installed. To confirm that SM artwork is genuinely editable, open it in a vector editor and check whether the letters are selectable paths or outlined shapes rather than an image object or unconverted text.
Preparing the favicon files
Favicon delivery commonly combines a scalable SVG version for browsers that support it with fixed-size raster versions for broader compatibility. These include an ICO file and PNG icons at several square sizes, such as larger icons used for mobile home screens. Exact size requirements vary by platform and change over time, so check current browser and operating system documentation before finalizing a file set.
- Review the smallest exports at actual size. Do not rely on a zoomed-in preview, which hides blurring and filled-in counters.
- Consider pixel alignment at the smallest sizes. Placing straight edges of the M on the pixel grid can keep them crisp instead of soft.
- Check light and dark backgrounds, since browser tab colors differ between themes.
- Keep the vector master and its exports together, so future edits start from the source rather than from a raster copy.
Rights: downloading is not the same as permission to use
If an SM logo or monogram comes from a template library, a logo maker, a freelancer or an existing brand, being able to download the file does not by itself grant the right to modify it, use it as a favicon or register it as a brand mark. Artwork licenses, font licenses and trademark rights are separate questions. A typeface used to build the S and M may have its own terms covering logo use. An existing SM mark may be protected as another organization's trademark. Review the applicable license and, where trademark questions arise, seek qualified advice before adopting a mark.
What this overview cannot confirm
Because no specific SM logo or brand was supplied, this article does not cover any particular design's appearance, file contents, licensing terms, cost or designer. It also does not assess how a specific SM favicon performs. Those details would need to come from the actual artwork files and their accompanying license or brand documentation.
