Picture-Hanging & Gallery-Wall Calculators
Free, practical calculators for getting art and photos on the wall — hanging height, gallery-wall spacing, art-to-furniture proportion, hardware weight ratings, frame-and-mat sizing, and salon-grid layout. Planning tools for arranging and displaying wall art, not professional installation advice.
Picture Hanging Height Calculator
Enter your art's height and the wire drop to get the exact nail height that puts the piece on the 57-inch gallery center line, plus the resulting top and bottom edges
Gallery Wall Spacing Calculator
Turn a wall width, frame width, count, and gap into the total row width, the empty wall to center it, and a center mark for every frame — an even, centered row the first time
Frame Size for Wall Calculator
Enter the width of the sofa, console, or wall the art hangs over and get the recommended art width at about two-thirds, a tasteful range, and the clearance to leave above the furniture
Hanging Hardware Weight Calculator
Enter a framed piece's weight to get the right picture-hook rating for one or two hooks, and a clear yes-or-no on whether you need a rated wall anchor or a stud
Frame & Mat Size Calculator
From your print size and mat border, get the mat window opening, the mat-board and glass size, and the finished outer frame — the full cut list for a matted frame
Salon Wall Grid Calculator
Enter rows, columns, frame size, and gap for the total frame count and overall footprint, then add wall dimensions to center the grid and confirm it fits
