Guide

Real estate sign sizes, riders and posts.

Standard sizes, what the riders and posts are called, and the city size limits that catch agents out, like Beverly Hills' 150-square-inch cap.

Updated October 19, 2026 · By the OpenHouse LA team

Standard sizes

  • For-sale panels: 18 x 24 inches is the standard. 24 x 36 inches is used for busy roads and deep setbacks and needs a heavier post or frame (4over4).
  • Riders: 6 x 24 inches is the default; 6 x 18 fits 18-inch panels; 4 x 24 for a second stacked rider. Riders usually hang from two S-hooks under the panel (4over4 rider guide).
  • Open house A-frames: most hold an 18 x 24 panel; larger 24 x 36 versions exist.
  • Square footage: an 18 x 24 panel is 432 sq in, or exactly 3 sq ft. A 6 x 24 rider is 144 sq in, or 1 sq ft.

What fits in each LA-area city

Common riders

Coming Soon, Open House, In Escrow or Pending, Sold, Price Reduced, a team or agent name, a phone number, or a QR code. In Beverly Hills a Sold, Leased or Rented rider can stay up 30 days at most (BHMC 10-4-104); in Pasadena, "open house" belongs on a rider rather than a separate sign (PMC 17.48.170).

Post types

  • Vinyl or PVC arm post: the familiar white post with a hanging arm. One common model is 6 ft with a 36-inch arm that holds signs up to 24 inches wide (example product); another stands 60 inches installed with a 32-inch arm (1-800-The-Sign).
  • Two-leg or "luxury" posts and metal frames: sturdier and common on higher-end listings.
  • Stake-mounted frames and A-frames: no digging; used for open house and directional signs.

Watch the height limits. West Hollywood caps signs on existing homes at 42 inches (WHMC Table 3-13) and Pasadena at 4 feet (PMC Table 4-22), shorter than a standard 5–6 ft arm post. Use a shorter post or frame there.

How deep does a post go?

There's no official standard. One manufacturer's instructions say to drive its arm post at least 24 inches deep (1-800-The-Sign).

Call 811 before you drive a post. California's dig law defines excavation as moving earth with tools, including "digging," "augering" and "driving," with no minimum depth (Gov. Code 4216(g)), and requires notifying DigAlert at least two working days before you start (Gov. Code 4216.2). Irrigation, gas and electric lines often run right where a sign post wants to go.
