Easy DIY Gallery Wall Tutorial

Instructions

1. Measure the width and height of the area you are going to install the picture array.
2. Measure the width and height of one picture frame (assuming they are all the same size).
3. Measure the offset from the top of your picture to where it actually hooks. This is very important to factor into the wall mounting positions.
4. Now we do some math! Let’s use as an example the following values - (you can change it depending on how many frames you want to use):
   
   Picture array 4 x 3
   Wall Width: 480cm
   Wall Height: 400cm
   Picture Height: 100cm
   Picture Width: 80cm
   Hanger offset: 20cm
   
   First, we calculate the vertical spacing:
   So horizontally we have 4 x Pictures = 4 x 80cm = 320cm and we subtract that from the wall width (480cm): 480cm-320cm = 160cm. Then take that number and divide by the number of picture frames width-wise (4): 160cm/4 = 40cm.
   This is the spacing between each picture frame horizontally. At furthest left and right edges the space would be half of this: 40cm/2 = 20cm
   
   Since the hanger is in the middle of the picture we need to offset our measurements.
   So working left to right the first horizontal position for a hanger nail would be:
   20cm(leftmost offset) + 40cm (half a picture width).
   Then relative to that marking, the next three points would be 40cm+80cm=120cm apart.
   
   Next, we calculate the horizontal spacing:
   We start with a similar calculation for figuring out the spacing between the outside of the frames as we did in the first part:
   Vertically we have 3 x pictures = 3 x 100cm = 300cm and we subtract that from the wall height (400cm): 400cm – 300cm = 100cm. Then we take that number and divide by the number of picture frames height-wise (3): 100cm/3 = ~33cm (it is ok to round to an even number).
   So now 33cm is the vertical spacing between the edge of each frame vertically.
   At the ceiling and floor, the space is half this so 33cm/2 = 16.5cm
   
   Since the hanging point is actually offset from the top of the frame by 20cm, we need to factor this into our vertical hole positions.
   
   So measuring from the floor our first marker would be: half the spacing (16.5 cm) + picture frame height (100cm) – hanger offset (10cm) = 106.5cm
   
   After that, the two other holes are each 100cm + 33cm from that first marker.
5. Using a tape measure try to draw this grid you have calculated very lightly with pencil and then mark the points where you will be mounting your hooks.
   
   If you have drawn the lines you can double check them with a spirit level to make sure they are truly vertical/horizonal.
   
   *Remember the age old adage: measure twice, drill once
6. With all the markings in place you are ready to drill/screw and mount your frames!

Tips: use some double-sided tape on the corners to avoid wobble.
