Estimate lineal footage for drywall edge trims and beads
Our drywall trim and bead calculator helps estimate the lineal footage of various edge trims needed for your drywall project. Corner beads, J-beads, and L-beads create clean, durable edges that protect drywall corners and exposed edges from damage.
The calculator determines quantities for outside corner beads (L-bead), exposed edge trim (J-bead), arch beads for curved openings, and paper tape for inside corners. It accounts for ceiling height and adds a waste factor since trims are sold in standard lengths.
This tool is essential for DIYers finishing basements or additions and anyone asking "how much corner bead do I need?" or "what drywall trim for exposed edges?" Having all materials on hand prevents mid-project delays and ensures consistent finish quality.
