Make it the full width of the porch or slightly wider depending on your porch design. If necessary use a sliding bevel to determine angles needed where the rafters will meet the ledger board. Find the wall studs or roof trusses that will have to support the ledger. Anchor deck joists to the ledger with joist hangers filling each hole with galvanized joist hanger nails rated for pressure treated wood.

This is the only way to ensure the connection is water tight. Determine how high it must be to provide an adequate slope to the roof. Locate a position for a header or ledger board.
