diagram of key measurements used in hangcalc

free gallery wall calculator makes positioning hanging fasteners easy so you can focus on the layout

  • suitable for home or gallery
  • use one or two hook hanging methods
  • full version is at hangcalc.com a progressive web app you can add to your home screen

There are many ways to hang pictures depending on fastening methods available, personal preferences, tools and equipment etc. These can range from simple arbitrary placement, use of centerlines, center points or edges; and may use simple tools like a spirit level and tape measure, or precision location using lasers. All are perfectly valid methods.

Some prefer to determine the centerline or center point for a picture or artwork and work from there. The center point (mid-line alignment height) is generally suggested to be 57 inches or 1450 mm high. Centerlines are used in these calculators, particularly for solo works and vertical groups.

These calculators focus positioning artwork centers and fasteners relative to edges or previous works. Using this method just four measurements are needed for each artwork:

  • vertical:
    1 outer vertical height
    2 drop to fasteners

  • horizontal:
    1 outer horizontal width
    2 inside adjustment to fasteners

Three other distances are used for positioning: 1 vertical height on wall, 2 vertical inter-work spacing; and 3 horizontal inter-work spacing.

I hope the calculators can be used to make relevant and helpful calculations for your purposes. For example, you can use "solo" to install works one by one in any position, or just complete inputs you need, eg. for horizontals or verticals.

main calculator

step 1. overall wall setup

  • the main calculator is for horizontal row layouts: step 1 defines overall features used in step 2 (horizontal spacing) and step 3 (individual works)
details

Four measurements may be needed for each artwork:
* vertical: 1) outer vertical height and 2) drop to fasteners
* horizontal: 1) outer horizontal width and 2) inside adjustment to fasteners (if using two)

Other distances used for positioning: 1) vertical height on wall, 2) horizontal inter-work or first/end spacing (ie. "to previous edge"); and 3) vertical inter-work spacing for a vertical group

The "number of works" field is used in calculations and should match entries made

step 3. individual work calculations

details
  • drop is to center of taught frame wire; or if 2 fasteners to top of D-rings; or stretcher depth if resting on nails or screws
  • inside adjust is for a two point hang only and is edges to D-ring centers; or, a set distance
  • "solo" can be used to hang each work one-by-one
  • "vert" can be used if there is a vertical group in a work position, the widest work in that group will often be the work position width for horizontal spacing

specific purpose calculators

  • three specific purpose calculators are included if you just want to calculate horizontal spacing, hang an individual work or one at a time; or hang a vertical group of works
using "horiz"
  • enter data into the "inputs" section, ie. the section width, each work's width and how many works. The results provide options for adjsting your spacings in various ways
using "solo"
  • enter data into the "inputs" section, ie. a work's chosen "reference height" and other details. The results are shown for vertical height options (ie. top edge, mid-line or lower edge at the reference height level) and relevant horizontal measurements
using "vert"
  • enter inputs for as many works as required up to a maximum of six. Inputs and results for both vertical and horizontal measurements are shown in the diagrams below

centers aligned

  • for center aligned groups a group section width needs to be set to establish a centerline
inputs and results for center aligned vertical group

edges aligned

  • the group's vertical edges can be aligned to the left or right
inputs and results for edge aligned vertical group
