Old vs. New Logos: How to Evaluate a Redesign

What you are actually comparing

An old-versus-new logo evaluation is a side-by-side reading of two visual identities, not a popularity contest. The essential answer is this: treat each version as a designed mark with measurable traits—shape, weight, spacing, color, type, and how it holds up at size—then decide whether the new mark is a clearer, more consistent expression of the same brand, a deliberate repositioning, or a weaker substitute. The object under discussion is the logo itself as a graphic system (symbol, wordmark, lockup, or combination), including the vector construction that makes those traits repeatable. Taste still matters, but it comes after the comparison, not before it.

Scope matters. A refresh usually keeps the recognizable skeleton and changes proportion, stroke, color, or type. A redesign replaces the skeleton. A lockup change can look like a new logo when only the arrangement of existing parts has moved. Compare like with like: mark against mark, wordmark against wordmark, full lockup against full lockup. If one file is a simplified app icon and the other is a horizontal lockup with a tagline, you are looking at two applications, not two identities.

Set up a fair visual comparison

Place both versions on the same background, at the same optical size, in the same color mode. Optical size means they occupy a similar visual mass, not that their bounding boxes share a pixel width. A thin wordmark next to a dense emblem will look smaller even when the files match. Align them on a shared baseline or geometric center so differences in x-height, cap height, and symbol height become visible.

• Use a light field and a dark field. Many marks that look balanced on white collapse or bloom on black.
• Check a one-color version of each. If the new mark depends on a gradient, a photo fill, or a fine outline to stay recognizable, that is a construction limit, not a style preference.
• View both at a large size and at a small size typical of favicons, app icons, and embroidered marks. Detail that only appears when zoomed in does not count as identity.
• If you have vector files, inspect them as paths. A raster screenshot of a logo is evidence of appearance, not of geometry. A .svg or .ai filename does not prove the artwork is true vector, editable, or legally reusable.

Geometry and silhouette

Start with the silhouette: the outer shape you would still recognize if the mark were filled solid. Circles, shields, letterforms, and animal profiles survive reduction; clusters of thin internal lines do not. Trace the old silhouette and the new one in your mind, then ask whether a viewer who only ever saw the old mark would still identify the new one at a glance. Continuity of silhouette is the strongest signal of a refresh. A new silhouette is a redesign, even if the name and colors stay the same.

Then read the internal geometry. Look at symmetry, axis, and how curves meet straights. Observable features include whether corners are sharp, slightly radiused, or fully rounded; whether strokes are even or have contrast (thick-to-thin, as in a serif letter); and whether negative space is an accidental gap or a designed counter. A mark whose counters close at small size will muddy. A mark whose outer contour is a simple, closed path will usually reproduce more cleanly in print, vinyl, and embroidery than one built from overlapping strokes, live effects, or stacked outlines.

Proportion, weight and spacing

Proportion is the relationship between parts: symbol to wordmark, cap height to line length, inner space to outer mass. A common redesign move is to thicken strokes and open letterspacing so the mark reads on screens. Another is to tighten everything so the lockup feels more premium in print. Neither is automatically better. Check whether the new proportions still hold when the lockup is stacked, when the symbol stands alone, and when the wordmark is used without the symbol. If the identity only works in one arrangement, the redesign has narrowed the system.

Weight is stroke thickness relative to the whole. Compare the old and new at the same size and ask which one still looks like a logo rather than a line drawing or a blot. Hairline marks disappear on fabric and in cheap print. Over-bold marks lose interior detail and can feel blunt next to fine product photography. Spacing includes tracking in the wordmark, the gap between symbol and type, and the padding implied by any containing shape. Uneven gaps, colliding letters, and a symbol that optically leans away from the type are construction problems you can see without knowing the brand strategy.

Color, contrast and reproduction

Color is part of identity only when it remains distinctive after you strip it away. Compare the palettes, then convert both versions to grayscale in your head. If the new mark is unreadable without a specific hue, the color is doing structural work that geometry should be doing. Note the number of colors, whether they are flat or blended, and whether light type sits on a dark field with enough contrast to pass a simple squint test. Gradients, glows, and photographic fills are observable treatments; they are also the first things to fail in one-color, small-size, and physical production.

Document what you can actually see: named or swatched colors if they are provided, otherwise the relative warmth, saturation, and value. Do not treat a marketing claim such as “more modern” or “more accessible” as a measured fact unless contrast, size, or color-count evidence supports it. A documented brand guideline that specifies a primary, secondary, and one-color lockup is stronger evidence than a social post showing only the full-color hero version.

Typography in the wordmark

If the logo includes lettering, compare the type as letterforms, not as a font name. Observable traits include serif versus sans, contrast in the strokes, the shape of terminals (cut, rounded, flared), the treatment of distinctive letters such as a, g, R, and ampersands, and whether the letters have been custom-drawn or only tracked and kerned. Custom lettering often shows in how a letter joins its neighbor or how a crossbar is redrawn to match the symbol. A font swap with default spacing is a lighter change than new letter construction.

Check optical alignment. Round letters such as O and C should slightly overshoot the baseline and cap line or they will look smaller than H and E. Wordmarks that ignore this look mechanically typeset rather than designed. Also check whether the new type still matches the symbol’s geometry: a geometric sans next to a calligraphic emblem, or a high-contrast serif next to a blunt pictogram, is a visible mismatch unless the redesign is intentionally splitting symbol and type into separate roles.

Vector construction versus appearance

Appearance is what you see at a given size and background. Construction is how the paths are built so that appearance can be repeated. In a vector logo, look for closed shapes, a limited number of anchor points on smooth curves, consistent stroke-to-fill conversion, and a clean separation between color areas. Overlapping strokes that only look joined, expanded outlines that leave stray points, and text that is still live (not converted to outlines) are construction issues. They may not show in a screenshot and still break when the file is scaled, cut, or handed to a printer.

Do not infer construction from a file extension. A file called logo.svg can contain an embedded bitmap. A PDF can be vector, raster, or both. Permission to use a mark does not follow from the file being public or easy to download. When you evaluate a redesign for production, ask for outlined artwork, a stated color system, and versions for light, dark, and one-color use. Those are the assets that turn a pretty comparison into a usable identity.

A practical scorecard

Work through the same questions for both versions. Write what you observe first, then your interpretation, and keep those two layers separate.

Lens | What to observe | What a change can mean

Silhouette | Outer contour at small size | Refresh if shared; repositioning if replaced

Geometry | Curves, corners, symmetry, counters | Cleaner drawing versus lost character

Proportion | Symbol-to-type ratio, stacking behavior | More flexible system versus one-lockup identity

Weight and space | Stroke thickness, tracking, gaps | Screen durability versus print refinement

Color | Count, contrast, one-color survival | Stronger system versus decoration dependence

Type | Letter construction, optical alignment | Custom identity versus generic typesetting

Construction | Closed paths, outlines, color separations | Production-ready file versus appearance-only art

Recognition | Could a prior viewer still name the brand | Continuity of equity versus a cold start

How to reach a conclusion

A redesign earns its keep when the new mark is more consistent across sizes and backgrounds, more distinctive in silhouette, and no harder to reproduce, while still carrying enough of the old geometry or lettering that existing audiences can transfer recognition. It fails when it is only a trend treatment—softer corners, a gradient, a thinner sans—on top of weaker structure. It is a true break when the silhouette, lettering, and color system all change at once; that can be the right business move, but it should be named as a new identity rather than sold as a tweak.

If you are choosing which version to keep, prefer the one that remains identifiable in one color at a small size, whose parts still work when separated, and whose vector construction is simple enough to cut, print, and screen. If you are documenting a change, record the observable deltas (thicker stems, wider tracking, new cap height, reduced color count, simplified counters) rather than adjectives. If a claim about the redesign cannot be pointed to on the artwork, treat it as editorial interpretation and give it less weight than the drawing in front of you.

Next step

Put the old and new marks on one sheet: large, small, light, dark, and one-color. Annotate only what you can see. Then decide, in one sentence, whether the new version is a refinement of the same mark, a replacement, or an incomplete system that still needs a standalone symbol, a stacked lockup, or a production-ready vector. That sentence is the informed conclusion; any file request or design brief you write next should follow from it.
