Comfort depends on more than the table footprint: players need a full cue swing around every rail. Draw the room to scale and keep clearance consistent on all sides.
A useful calculation
Add twice the working cue length to the table's length and width. Then include rail thickness, skirting boards and the light fitting's projection. A short cue can solve one awkward shot, but it should not replace safe walkways.
Furniture and delivery
Mark the table rectangle with painter's tape. Check door swings, player positions at each pocket, sofas and cabinets. Measure the narrowest corridor and every turn for the packaged sections before ordering.
Sensible compromises
If the room is tight, short cues help occasionally but cannot make a cramped layout pleasant. A smaller table format is usually better than repeated cue strikes on walls and furniture.
Ask for an installation drawing and confirm ceiling height for the light before paying.
