The short answer
Pick one casing and one baseboard profile for the whole building, matched to the door style. Flat and bevelled profiles suit flush and Shaker doors; colonial and ogee profiles suit moulded panel doors. Simpler profiles have fewer edges to paint and touch up at turnover.
Match the trim to the door
| Door style | Casing | Baseboard |
|---|---|---|
| Flush and grooved | Square flat (DC004), eased flat (DC003) | Square edge (BB009), bevel top (BB006) |
| Shaker | Tapered flat (DC008), square flat (DC004) | Bevel top (BB006), tall bevel (BB007) |
| 2-panel moulded | Colonial (DC001), ranch (DC005) | Colonial ogee (BB001), step ogee (BB008) |
| 6-panel and arch top | Ogee (DC009), ornate bead (DC006) | Ornate colonial (BB003), tall ogee (BB004) |
See every profile on our trim page, and the doors each pairs with in moulded, Shaker or flush doors.
What makes trim easy to own
- Fewer details. Every bead and step is another edge to cut in at turnover. Flat and bevelled profiles repaint fastest.
- One profile. A single casing and baseboard across every suite means one stock length in the maintenance room.
- Proportion. Taller baseboard and wider casing look right with higher ceilings. In a standard 8′ suite, keep both modest. We confirm exact sizes on the quote.
- Shoe where the floor needs it. Floating floors often need shoe moulding to cover the expansion gap. See quarter round vs base shoe.
How trim is ordered
| Item | Ordered by |
|---|---|
| Casing | The opening, one set per side, or the linear foot |
| Baseboard | The linear foot, taken off the floor plans |
| Shoe moulding | The linear foot, usually matching the baseboard run |
| Crown | The linear foot, for living areas and upgrade units |
A 30″ to 36″ door takes about 34 linear feet of casing for both faces. For baseboard per unit type, see the takeoff guide. Every profile comes in MDF or finger-jointed pine; see which to use where.
