Why a mockup beats a measurement
Numbers on paper are accurate but abstract. A width of a certain size means little until you see where it ends in your hallway. A mockup turns the measurement into something you can walk around, sit near and see from the doorway. It tends to expose problems that a tape measure does not: a unit that feels huge, a path that is too tight, a desk that would block the light.
The method is inexpensive and reversible, which suits a purchase that is hard to undo.
What you need
- Painter’s tape or masking tape, which usually lifts off floors more easily than other tapes (test a hidden spot first).
- Cardboard boxes, flattened or assembled, or old packaging.
- Newspaper or wrapping paper for large floor outlines.
- A tape measure, a marker and scissors or a box cutter.
- Optional: string, stools, chairs and laundry baskets as stand-ins.
Step 1: Outline the footprint on the floor
Start with the plan. Take the length and depth of each module from the product details and mark the rectangle on the floor with tape. For a sectional, mark each section so you can see the shape, including any chaise or corner. Label the pieces with a marker on the tape or on paper.
Check that you have included protruding parts such as arms, legs and the swing of doors and drawers. If you are weighing a few shapes, mark each in a different color of tape or lay them out one at a time. Our article on choosing a sectional shape covers what to compare.
Step 2: Add height
Floor outlines can hide the effect of height. For taller pieces, build a rough volume:
- Stack boxes to the intended height and shape.
- Tape cardboard sheets to a wall to show the top edge of a shelving unit or wardrobe.
- Hang a sheet of paper or a string line at the height of a headboard or a wall shelf.
Stand back and look from the door and from where you usually sit. Look at how it relates to windows, light switches, sockets and ceiling lines. This is also a good time to think about how it will affect room lighting.
Step 3: Test the walkways
This is where mockups earn their keep.
- Walk the routes you use every day, such as from the door to the sofa, or from the bed to the wardrobe. Carry something bulky, like a laundry basket, to simulate real use.
- Open the doors and drawers: if a drawer unit is represented by a box, mark the pull-out distance with tape.
- Sit in a chair at a desk mockup and push back as you would normally, to see whether you hit anything.
- Ask everyone in the household to try it. A space that works for you might be awkward for a child, or for someone using a mobility aid.
Comfortable clearance varies with the room and the person, so rely on how it feels in use rather than on a fixed number. If you are tight, shrink the layout rather than squeezing the walkway. Read about planning walkways and clearance if you want to go deeper into traffic flow.
Step 4: Live with it
Leave the mockup in place for several days if you can. Notice what annoys you: stubbed toes, shadows, a blocked view of the window, a heater that is covered. Go through your normal routines, including cleaning, since a unit that is difficult to vacuum around may bother you in a month.
If a mockup is too intrusive to leave out, take photos and revisit them, or leave it only through an evening and a morning.
Step 5: Adjust and record
Move the tape and boxes around. Moving a mockup is far easier than moving a real wardrobe. When you find a layout that works, measure and record the positions, and take photos for later reference. Then check the final plan against the product dimensions once more.
Variations for different situations
- Shelving and wardrobes. Stack boxes to approximate the height and check against sloped ceilings, skirting boards and light fittings.
- Beds. Use a sheet or flattened boxes to mark the mattress area, and sit on the edge to see whether you have room to dress.
- Desks. Tape the work surface, then place a laptop and a chair in position to test posture and reach.
- Kitchens. Use tape to mark island or cart footprints. Check how far appliance doors open.
- Rentals. Tape is gentle on most surfaces, but test an unseen spot first.
The limits of a mockup
A cardboard version cannot tell you about comfort, firmness, color or build quality. It will not show how the real piece looks in terms of visual weight, either, although boxes help. Treat the mockup as a test of fit and flow, then use samples and specification checks for everything else.
Done well, an afternoon with tape and boxes often prevents the costliest mistake: buying something that simply does not belong in the room.
