To calculate the quantity and size of picture rail needed for a hanging project, it is important to consider several parameters. Here is a step-by-step guide:

1. Measure the length of the wall

• Measure the total length of the walls where you want to install the picture rails.
• If you plan to install picture rails on multiple walls, add up their lengths.

2. Consider angles and junctions

• If your walls include corners or junctions, plan for connecting accessories (internal or external corners).
• These elements may sometimes require a slight adjustment in the length of the rail.

3. Determine the desired height

• The picture rails can be mounted either:
  • Close to the ceiling (classic and aesthetic solution).
  • Mid-height (option sometimes used for specific hangings, such as in art galleries).

4. Calculate the number of rails

• Picture rails are often sold in standard lengths (e.g., 2 meters or 3 meters).
• Divide the total measured length by the length of a standard rail to determine the number of rails needed.
  • For example: if your wall measures 5 meters and the rails are 2 meters, you will need 3 rails (5 ÷ 2 = 2.5, rounded up to 3 rails).

5. Provide fixing clips

• Provide clips every 30 to 40 cm for stability.
• Number of clips = total length of the rails ÷ recommended spacing.

6. Suspension wires and hooks

• Depending on the number of artworks to hang:
  • Count one wire per artwork or more if the artwork is wide.
  • Wires are often sold in sets or individually (standard length between 1 and 3 meters).
  • Provide one hook per wire, or two if the artwork is heavy or wide.

Calculation Example:

6-meter wall with 4 artworks to hang:

1. Required Rails:

   • Wall length = 6 m.
   • 2-meter rails → 6 ÷ 2 = 3 rails.

2. Required Clips:

   • Spacing = 40 cm.
   • Total length = 600 cm ÷ 40 cm = 15 clips.

3. Suspension Wires:

   • One wire per artwork → 4 wires.
   • Plan for additional wires if needed (adjustments or new artworks).

4. Hooks:

   • Minimum one hook per wire → 4 hooks.

Additional Tips:

• Add a margin: Plan for one or two extra rails for adjustments or to expand the configuration in the future.
• Plan for accessories: Consider end caps, angles, or connectors if your walls require junctions.
• Ask for advice: If you are buying picture rails from a specialized store, provide your measurements for personalized assistance.
