Space Plan
A test fit is a rough layout drawn over a floor plan to answer one question: does this space actually work for what you do? For a practice, that means checking whether you can fit the number of operatories or exam rooms you need, plus reception, lab, sterilization, offices, and circulation, without cramming.
It is usually inexpensive or even provided by the landlord during negotiations, and it is one of the smartest things to do before signing. A space that looks right on paper by square footage can turn out to hold two fewer operatories than you need once walls, corridors, and code-required clearances are drawn in.
Square footage alone does not tell you if a space fits your practice. A test fit before you sign is cheap insurance against committing to a space that cannot hold your room count or grow with you. Always get one during negotiations, not after.
A dentist is deciding between two suites of nearly identical size. A test fit shows the first fits seven operatories cleanly, while the second, because of a column line and window placement, fits only five. That single drawing changes which lease makes sense.
