Hello,
Thank you for your comment and for using ‘Kaya QR Code Generator’.
There is no default image size in the plugin’s general settings, the only default settings present are color and background color.
Regarding the size of the image, as well as all other options in the settings of the “Kaya QR Code Generator” panel available in the post editor, are not used as custom fields for the post and in no way affect the content of the page.
The Shortcode generator assistant is used to help build the shortcode structure. The generated shortcode must be pasted on a “shortcode block” or directly in the page content.
The automatic size of the QR Code image is generated mainly based on the content and the level of repetition of the information. The pixel size field is used to give a desired size, which is taken into account and adapted according to the two parameters mentioned above.
To use this parameter in a shortcode you must therefore integrate it in this way, for a size approaching 300px for example:
[kaya_qrcode size="300"]
Let me know if that helps you.
Thank you, best regards.
