01 · Getting started
Make a simple sketch before taking measurements
Use a tape measure, paper, and a pencil to draw a rough outline of the office. Add the date, room name, and a label for each wall. The first sketch does not need to be to scale; it needs enough space for readable measurements and notes.
Choose one unit system and use it throughout. For many U.S. furniture orders, recording dimensions in inches makes comparison with product drawings easier. If you also write feet and inches, label them clearly rather than switching between the two without explanation.
Take photos from each corner and toward the entrance. Match them to the wall labels on your sketch. Photos explain features that can be hard to draw, but they should support your measurements rather than replace them.
Room outline
Record wall lengths, recesses, corners, columns, and changes in the room’s shape.
Fixed features
Mark doors, windows, outlets, vents, and built-in fixtures.
Furniture in use
Allow for occupied chairs, open drawers, cabinet doors, and people moving through the room.
Delivery access
Note entrances, corridors, elevators, stairs, and turns that the furniture must pass through.
02 · Room dimensions
Measure the full room and each usable wall section
Record the inside length and width of the room. Then measure individual wall sections between corners, doors, columns, and built-in features. A long wall interrupted by a doorway may offer much less space for a desk and storage than its overall length suggests.
For an L-shaped room or one with a recess, divide the sketch into simple rectangles. Measure each section and label where it joins the next. Do not use the room’s longest and widest dimensions as though they describe one open rectangle.
Check more than one point along a wall where the fit is tight. Baseboards, trim, and changes in the wall surface can affect where furniture sits. Record the narrowest relevant space and note anything that projects into it.
Measure ceiling height where you plan tall storage. Include bulkheads or other overhead features that reduce the available height. If a cabinet needs to be assembled upright or tipped into position, ask the installer how much working space that requires.
03 · Doors and fixtures
Locate features from a fixed reference point
Choose a corner as your starting point for each wall. Measure from that corner to the near edge of a window, outlet, column, or other feature. Record the feature’s width as well. This gives the person reviewing the drawing a clear location instead of a mark that only looks approximately right.
Mark which way each door opens and show its swing on the sketch. Include closet doors and doors on built-in cabinets. Open them fully to see which part of the floor they use.
Record window-sill height and the position of heaters, vents, and access panels near proposed furniture. Note outlet heights if a desk, cabinet, or panel could cover them. Furniture should not prevent the access these features need.
If a cable opening or monitor mount must line up with a particular location, flag it on the drawing. Ask the supplier to review that detail against the product specification.
04 · Furniture footprints
Draw furniture to scale and check it in use
Use the dimensions of the exact products you are considering. For desks with returns, ask for a drawing of the complete arrangement. Overall dimensions may differ from the sum of the individual parts because the surfaces can overlap.
Choose a consistent scale for your plan. For example, one-quarter inch on paper can represent one foot in the room. At that scale, a five-foot desk is one and one-quarter inches wide on the drawing. Label the scale so someone else can read it correctly.
Show more than the furniture’s closed outline. Add the space used by a chair when someone sits down, a drawer when it opens, and a cabinet door when it swings outward. Check how these areas interact with the routes people use.
A wall measurement is only the starting point
Suppose a usable wall section measures 120 inches. A 60-inch desk and a 36-inch cabinet total 96 inches, leaving 24 inches along that wall. The subtraction is correct, but it does not establish that the setup works. You still need to check furniture depth, door swings, drawer access, and chair movement. The remaining space is not automatically a usable passage.
For a final layout, have building management and the appropriate project professionals confirm access and exit requirements. A furniture drawing alone does not establish that those requirements are met.
05 · Try the layout
Mark the proposed furniture positions on the floor
If the room is available, use removable floor-safe tape to mark the outlines of the main pieces. Check the tape on a small area first and get permission before using it on someone else’s flooring.
Place a chair in the proposed workstation and move it as you would during the day. Walk from the door to the desk, storage, and shared equipment. Try the room with another person seated so you can notice conflicts that an empty outline may hide.
Think through ordinary tasks: carrying files to a cabinet, meeting a visitor, or reaching a shared printer. If the arrangement only works when chairs are tucked in and storage is closed, revise it before choosing the final pieces.
Use this test to compare layouts, then record any changes on the drawing. Keep one clearly dated version as the plan for the quote.
06 · Delivery route
Measure the route from the entrance to the office
Walk the full delivery route and record its narrowest openings, low points, and turns. Note door hardware, handrails, trim, and other projections. For an elevator, record the doorway and interior dimensions; for stairs, photograph landings and overhead restrictions.
Give these details to the delivery team along with the proposed furniture list. Ask about the size of the largest package or assembled component and whether parts can be removed according to the manufacturer’s instructions. A doorway measurement alone cannot confirm that a large piece can make a turn.
Also ask building management about loading access, elevator reservations, permitted hours, and paperwork. A piece may fit the route but still require delivery arrangements that need to be made in advance.
07 · Final review
Share the measurements before approving the order
Send the supplier your labeled sketch, photos, proposed layout, and delivery-route notes. Identify tight areas and measurements you could not confirm. An unanswered question is easier to resolve before an order is placed.
Bring the same information when discussing commercial office planning with 309 Office Furniture. Ask what additional site information or measurements the team needs for your project.
Review the final product drawing against your room measurements and the quote. Confirm the orientation of returns, drawer locations, overall sizes, and delivery responsibilities. If room finishes or construction change after you measured, check the affected dimensions again before final approval.
Frequently asked questions
Do I need a professional floor plan before visiting the showroom?
A labeled sketch with wall lengths, doors, fixed features, and photos can start the discussion. Tell the team which measurements are uncertain. More complex projects may need a site visit or additional drawings before furniture is ordered.
Should I measure the room in feet or inches?
Either can work if the units are clear and consistent. Recording inches can make comparison with U.S. furniture specifications easier. Avoid mixing an unlabeled decimal measurement with feet-and-inches notation.
How much space should I leave behind an office chair?
It depends on the chair, how the space is used, and whether people need to pass behind it. Test the chair in its working and pulled-out positions. Have the final layout reviewed for the requirements that apply to the room.
Can I rely on an existing building floor plan?
Use it as a starting point, then check key dimensions on site. The drawing may not show later changes, trim, built-in features, or the exact conditions at a tight furniture location. Mark your corrections and the date.
What if the furniture fits the room but the delivery route is tight?
Send route measurements and photos to the delivery team before ordering. Ask about package sizes, separate components, and permitted assembly options. Have the team review the route rather than assuming the piece can be turned or taken apart.
