Common shapes are rectangular, round, and oval tabletops — each shape is represented across the available farmhouse/barn-style dining table options.
Most list standard dining heights around 29.9 to 30.4 inches. Several listings show about 29.9–30 inches, with one extendable design listed at approximately 30.4 inches.
Common bases include four‑leg (4‑point) designs, single or double pedestals, X‑ or crisscross metal bases, and V‑shaped or thick rectangular leg supports depending on the model.
Tabletops are often described as engineered wood or MDF (sometimes with a veneer) or simply 'wood.' Frames and legs are listed as wood or metal (iron/steel) depending on the design.
Most listings indicate adult assembly is required and include tools, labeled parts, and clear instructions to make assembly straightforward.
Listings mention finishes such as waterproof or water‑resistant surfaces, dust‑proof or anti‑corrosive coatings, and scratch‑ or stain‑resistant laminate or sealed finishes. Many note easy‑clean care (e.g., 'wipe clean' or spills wiped away with a damp cloth).
