The short answer

To scale a logo proportionally in Photoshop, select its layer, open Free Transform (Edit > Free Transform, or Ctrl+T on Windows and Cmd+T on macOS), and drag a corner handle. Current versions of Photoshop keep the proportions locked by default when you drag a corner, and holding Shift switches to free, non-proportional scaling. For exact sizing, type a value into the width or height field in the options bar with the link icon between them switched on, so the other dimension updates to match. Press Enter or Return, or click the check mark, to commit the change.

Proportional scaling means the width and height change by the same percentage, so the logo's aspect ratio (the relationship between its width and height) stays the same. If the two values differ, letterforms and symbols are stretched or squashed, which is usually not acceptable for brand artwork.

Keeping the proportions right is only half the job. How sharp the logo stays depends on what kind of layer you are scaling, because Photoshop is mainly a raster (pixel-based) editor, not a vector one.

Why the layer type decides the quality

Vector artwork describes shapes as mathematical paths. A path is a line or curve defined by anchor points, which can be redrawn cleanly at any size. Raster artwork is a fixed grid of pixels. When Photoshop resizes pixels, it has to resample them, which means calculating new pixel values. Enlarging a raster logo softens edges and can blur small text. Repeatedly shrinking and enlarging the same pixel layer loses detail each time.

Layer type | What happens when you scale it | Suitability for logo work
Pixel (regular) layer | Pixels are resampled on every committed transform; enlarging softens edges | Acceptable for reducing a one-off export; avoid enlarging or repeated transforms
Smart Object containing pixels | The original pixels are preserved inside the Smart Object, so repeated transforms do not compound damage; enlarging beyond the original pixel size still softens it | Good for safe experimentation with raster logos
Smart Object containing placed vector content (for example from a PDF, AI or SVG file) | The vector data is kept inside and re-rendered at the new size | Best option when the logo must stay crisp in a Photoshop layout
Shape layer or type layer | Paths and live text are redrawn at the new size | Crisp at any size, as long as the artwork was built from shapes or live type

A file extension is not proof of what a file contains. An SVG, AI, EPS or PDF can hold embedded raster images, and a logo saved in one of these formats is not automatically fully vector, editable, or cleared for reuse. Check the artwork itself and the usage rights before relying on it.

Step by step: scaling a logo layer proportionally

  • 1. Open the document and, in the Layers panel, select the layer or group that contains the logo.
  • 2. If it is a pixel layer, right-click it and choose Convert to Smart Object, so the original data is protected. If you have the logo as a vector file, bring it in with File > Place Embedded or File > Place Linked instead of pasting pixels. This keeps it as a vector-backed Smart Object.
  • 3. Choose Edit > Free Transform (Ctrl+T or Cmd+T).
  • 4. Drag a corner handle to resize. Do not hold Shift unless you want to break the proportions. To scale from the center, hold Alt (Windows) or Option (macOS) while dragging.
  • 5. For a precise size, use the W and H fields in the options bar. Make sure the link icon between them is active, then enter a percentage or a measurement in one field.
  • 6. Commit the transform with Enter or Return, or the check mark in the options bar. Press Esc to cancel.

If corner-dragging in your copy of Photoshop distorts the logo unless you hold Shift, check Preferences > General. The Use Legacy Free Transform option restores the older behavior, where Shift is required to keep proportions.

Scaling the whole file instead of one layer

If the document is only the logo and you need a different output size, use Image > Image Size. Keep the link icon between Width and Height active so the aspect ratio is constrained. The Resample option decides whether Photoshop adds or removes pixels. With Resample turned off, changing the resolution only changes the print size and leaves the pixel dimensions alone. With it on, the pixel dimensions change and the same quality limits as Free Transform apply. Image > Canvas Size is different: it changes the space around the artwork and does not scale the logo.

How to verify the result

  • Before committing, confirm the W and H values in the options bar show the same percentage.
  • After committing, select the layer and reopen Free Transform to read the current scale relative to the original. This works on Smart Objects. On a plain pixel layer the reference resets to 100% after every commit.
  • View the document at 100% zoom (View > 100%) and inspect curves, thin strokes and small text for softness or jagged edges.
  • Compare the scaled logo with a reference copy of the approved artwork to catch any stretching that is hard to see by eye.
  • If the logo looks soft after enlarging, the source is probably raster. Replace it with a vector or higher-resolution master rather than sharpening it.

When Photoshop is the wrong tool

Photoshop is suitable for placing and sizing a logo inside a raster layout, such as a web graphic, mockup or photo composite. It is not the right place to build or maintain the master logo. Resizing master artwork, adjusting path geometry, or preparing scalable delivery files for print and digital use is better done in a vector editor, with exports produced from that vector source.

Gaps in this guide

No source evidence was supplied for this topic, so this guide gives no specific pixel dimensions, resolutions, minimum logo sizes or version-specific details. Menu names and default behaviors reflect general Photoshop practice and may differ slightly between versions. Any minimum-size or clear-space requirements for a particular logo should come from that brand's own guidelines.
