About OprawTo
How the service works, who it is for and its limitations.

OprawTo helps calculate dimensions, plan layouts and organise framing projects. It does not replace a conservator or appraiser.
Data
Projects, materials and checklists are stored locally. No account is required.
Method
Calculations use rectangle geometry, aspect ratios and explicit assumptions shown with every result.
