To determine the right length, first, consider how high you want the top surface of your piece to be overall, and then deduct the thickness of the material you will be mounting the legs to. For example, if you want your dining room table to stand at 30” high and your wooden tabletop is 2” thick, we recommend 28” hairpin legs.
Below is a list of standard hairpin lengths for common DIY hairpin projects.
6” - Platform Bed
8” - Raised Sofa
10” - Raised Sideboards, Media Stands, Record Cabinets
12 - 18” - Coffee Table (the table should be lower than 2” from the seat of your couch)
16” - Bench, Stool
20” - End Table, Side Table to complement a standard coffee table
25” - Nightstand
28” - Dining Table, Desk (there should be 12” between your seating and the top of the table).
28 - 30” - Entryway, Foyer Table, Console Table, Sofa Table (the table should be level with the back of the sofa or 1” below it)
