I would like to suggest aligning the grid spacing and the ruler in GoodNotes with common measurement standards.
In many countries (for example in Europe), squared paper follows a standardized pattern where two squares equal exactly 1 cm. This standard is widely used in schools, universities, and technical work.
Currently in GoodNotes, however, two squares correspond to about 1.12 cm when measured with the built-in ruler. Because of this mismatch, the ruler becomes difficult to use for precise measurements or technical sketches. Lines drawn using the grid do not correspond correctly to real-world measurements.
This can be especially inconvenient for students, engineers, architects, or anyone who relies on accurate spacing when sketching diagrams or technical drawings.
Suggestion:
* Adjust the grid so that 2 squares = exactly 1 cm, matching common squared paper standards.
* Ensure the digital ruler corresponds precisely to the grid spacing.
Alternatively, it could also be helpful to provide a “standard metric grid” option in the template settings.
This change would make the ruler far more practical and would allow GoodNotes to better replicate real squared paper used in education and technical fields.

Thank you for considering this improvement
