1. The front door
Provided the furniture won’t need to turn around a corner as soon as it enters your front door, find the design’s smallest measurement (usually the height of a sofa, the width of an armchair, or the depth of pieces like wardrobes and dressers). If the width of the door is greater than this, then it’ll fit through. Remember to take into account the door itself, unless you’re able to take it off its hinges or it can be opened 180°. And it’s always best to leave a little extra space (three–five centimetres) as wiggle room.
If there’s a wall opposite your front door that your piece will need to turn to avoid, it may be easier to take it in upright or on its side, especially if it’s a long, tall or wide design such as a sofa or wardrobe. In this case, as long as the height of the door frame is taller than your piece’s longest measurement, it’ll fit. Again, make sure to allow for wiggle room and be aware of any low-hanging light fittings.
