I have a question: My developer does math for matching dimensions between the screens I (the designer) give and the layout she makes. There is a formula for it, but she forgets after a project is over and she has to start all over again. Is there anything I can do as a designer to minimize her head banging hours. Is there a certain formula or layout I should design around to make things a bit easier for her. Thank you to anyone who responds it is greatly appreciated.
