Hi Fabrice,

I don't understand what you wrote. Please use English. For example, DeepL Translator.

Share also URL of your website, and what shape has your logo.

Website > Helix Ultimate 2.2.4

Hello, What pixel size should I choose so that the logo at the top of the site is clearly visible? Template used: celestia - Default It does look very small. Thank you for your help

1. Share URL of your website (if you can)
2. What shape has your logo (square or rectangle) ?

the logo is a square

Go to Template Options > Basic > Logo > Logo Height 90px or 100px > Save & Close

If somehow above method will not help, please use below Custom CSS:

#sp-logo img.logo-image {height: 100px;}
