White space is the area between design elements. It is also the space within individual design elements, including the space between typography glyphs (readable characters).
Despite its name, white space does not need to be white.
White space can cause problems between designers and clients. Design theory promotes the use of white space for elegance and ensuring a quality user experience. Sadly, many clients and managers consider white space wasted space. They think it could be used to house more information or other visual elements.
White space is a great tool to balance design elements and better organise content to improve the visual communication experience.
