How to Measure Your Room for a Custom Sofa

2026-09-24 · TY Furniture Factory

To size a custom sofa, measure both the space where it will stand and the route used to deliver it. Then confirm the sofa's overall dimensions, seating proportions and orientation on a drawing. Choosing a size from a photograph alone leaves too much unresolved.

Draw the room before choosing the sofa dimensions

A simple sketch is enough to begin. Mark the wall lengths, door openings, windows and any fixed features that affect furniture placement. Include the television, coffee table and other pieces you intend to keep. Label every measurement with its unit.

Measure the usable space rather than assuming the full wall is available. A door may need room to open, curtains may occupy part of a corner, and a walkway may cross the area where you want the sofa. Record these limits so the factory understands the layout.

Mark out the proposed footprint

Use a removable floor marking method suitable for your flooring to outline the proposed width and depth. Walk around the outline, open nearby doors and consider how people will reach the seating. Include the chaise or corner section in its actual position.

This is a planning exercise, not proof of a comfortable fit. Think about where you will stand up, how you will reach a coffee table and whether another chair can still be used. Adjust the outline before deciding on the dimensions to send for a quotation.

Tell the factory how you want to sit

Overall depth is not the same as seat depth. The back structure and cushions take up some of the sofa's footprint. If you prefer upright seating or a deeper lounging position, describe that preference and ask which measurements the drawing will show.

An existing sofa that you find comfortable can provide a useful reference. Measure it and explain what you want to keep or change. Treat those measurements as a discussion point: different cushion and back arrangements can feel different even when the overall size is similar.

Make the chaise direction unambiguous

For an L-shaped design, send a top-view sketch showing the chaise, the wall and the direction the sofa faces. Words such as “left” and “right” can be interpreted from different viewpoints. A marked plan is a clearer instruction.

If you want separate modules, show the intended arrangement and ask how the sections connect. Confirm whether the layout is fixed or whether any rearrangement is actually supported by the agreed design.

Check the whole delivery route

Record the narrowest door openings, corridor turns, stair landings and relevant lift dimensions. Tell the factory about restrictions before production. If needed, ask whether removable parts or separate sections are feasible and how that changes assembly.

Do not compare only the finished sofa width with the front door width. Height, depth, packaging and turning space also matter. Ask the factory and delivery provider to review the proposed transport arrangement; a basic room sketch cannot guarantee that a packaged piece will pass through every turn.

Send one clear measurement brief

Your brief should include the room sketch, preferred overall sofa dimensions, seating preferences, chaise orientation and access restrictions. Attach the selected sofa design or its product code so the dimensions are connected to the right piece.

At TY Furniture Factory, size is part of the customization discussion. The production drawing should be checked and approved before manufacturing. Our drawing approval checklist explains what to review when that drawing arrives.

If you are still unsure, send the available measurements and identify the unresolved points. It is better to discuss a doorway or seating question early than discover it after the design has been approved.
