Set a visual datum that also works in use
A frame can be level yet look wrong when the floor slopes, a cornice changes height or furniture sits off-centre. Decide which reference matters: the item below, the room axis, a group of pictures or the viewer’s normal position. Then check doors, curtains and circulation. For a television, comfort and cables matter more than aligning with a decorative moulding. For shelves, the proposed contents determine spacing and load. Use removable paper templates where a group needs approval. This planning separates visual preference from technical support, allowing the final location to satisfy both instead of discovering the conflict after holes have been made.
