@@ -99,7 +99,7 @@ Layout options are set as options to the `\documentclass`, e.g.:
 - `logoinqr` or `nologoinqr`: place logo in the center of the QR code (`logoinqr`) instead of next to the name, default: `nologoinqr`. **Requires `qreclevel=H` for reliable scanning**.
 - `qrlogoscale=`: logo size in QR code as fraction of QR width (1.0 = 100%), default: `0.25` (25% width). Recommended values: Level H: 0.25-0.3, Level Q: 0.2, Level M: 0.15, Level L: 0.1. Higher values may reduce scannability.
 - `qrlogoborder=`: transparent padding around logo in QR code as fraction of QR width (1.0 = 100%), default: `0.02` (2%). Adds space between logo and QR modules.
-- `logoscale=`: scale factor for logo next to name (1.0 = 100% of name height), default: `1.0`. Use values like `2.0` or `2.5` for larger logos.
+- `logoheight=`: logo height next to name with unit (e.g., `4em`, `6em`), default: `4em` if company is set, `2em` otherwise.
 - `bgscale=`: background image scale factor (1.0 = 100% of card height), default: `1.0`. Use values like `1.5` or `2.0` for zoomed/cropped backgrounds. Only affects images, not colors.
 - `bgopacity=`: background image opacity/transparency (1.0 = 100% visible, 0.0 = invisible), default: `1.0`. Use lower values like `0.2` or `0.3` to fade the background so text remains readable. Only affects images, not colors.
 - `qrbgopacity=`: QR code background opacity (1.0 = solid white, 0.0 = transparent), default: `1.0`. White background behind QR code ensures scannability over background images. Use `0.0` for no background or lower values like `0.8` for semi-transparent.
