Quick Answer
To measure your wall space for a custom poster print, first determine the ideal viewing distance and the proportion of the wall you want the poster to fill. Then, measure the width and height of that area, subtract a margin for breathing room, and choose a poster size that fits within those dimensions. Always account for the frame size, as the frame adds several inches to the overall footprint.
Turning your child's artwork into a custom poster print is a wonderful way to celebrate their creativity and add a personal touch to your home. But before you order, you need to know exactly how much wall space you have. Measuring correctly ensures the poster fits perfectly, looks balanced, and doesn't overwhelm or get lost in the room.
This guide walks you through the simple process of measuring your wall space, choosing the right poster print size, and planning for framing. Whether you're decorating a playroom, a hallway, or a home office, these steps will help you create a display you'll love.
Step 1: Identify the Wall and Viewing Distance
First, decide which wall you want to decorate. Consider the room's purpose and how often you'll see the poster. A playroom might call for a vibrant, large print, while a hallway may suit a smaller, more subtle piece. The viewing distance matters: for a poster you'll see from across the room, a larger size works better; for a close-up view, a smaller size can be just as impactful.
A good rule of thumb is that the poster should occupy about 60-75% of the available wall space, leaving some empty wall around it for visual balance. If the wall is empty, measure the entire width and height of the wall. If there's furniture or other decor, measure the open space between them.
- For a standard 8-foot ceiling, a poster that is 24x36 inches works well on a large wall.
- If the wall is partially covered by a sofa or bookshelf, measure the clear area above or beside it.
Step 2: Measure the Width and Height
Using a tape measure, record the width and height of the wall space you've identified. Write these numbers down. If you're planning to hang the poster at eye level, measure from the floor to about 57-60 inches, which is the standard gallery height. For a child's room, you might hang it lower, so adjust accordingly.
Subtract a margin of 2-4 inches on each side and top/bottom to give the poster breathing room. For example, if your wall space is 48 inches wide and 36 inches tall, you have a usable area of about 40x28 inches. This gives you a maximum poster size of roughly 40x28 inches, but you can choose a smaller standard size like 24x36 or 18x24.
- Always measure twice to avoid mistakes.
- Consider the orientation: landscape (wider than tall) or portrait (taller than wide) based on your child's artwork and wall shape.
Step 3: Choose the Poster Print Size
Now that you have your maximum dimensions, compare them to standard poster sizes. Common sizes include 8x10, 11x14, 16x20, 18x24, 24x36, and 30x40 inches. If your child's art is a square, you might prefer a square poster, but standard sizes are easier to frame. If your wall space is large, a 24x36 poster is a popular choice; for smaller spaces, an 18x24 works well.
Remember that the poster's aspect ratio should match your child's artwork as closely as possible to avoid cropping. If the art is portrait-oriented, a portrait poster is best. If it's landscape, choose a landscape poster. If you're unsure, you can always order a custom size, but standard sizes are more affordable and easier to frame.
- For a child's bedroom, a 16x20 or 18x24 poster is often the perfect size.
- For a living room or entryway, consider a 24x36 poster to make a statement.
Step 4: Account for the Frame Size
If you plan to frame your poster, remember that the frame adds several inches to the overall dimensions. A typical frame adds 1-3 inches per side, depending on the frame width. So a 24x36 poster in a 2-inch frame will take up about 28x40 inches of wall space. Make sure your measured area can accommodate the framed size.
When choosing a frame, consider the style of your room and the poster's colors. A simple black or white frame is versatile, while a wood frame adds warmth. Also, decide whether you want a mat; a mat adds extra space between the poster and the frame, which can enhance the look but also increases the overall size.
- Measure the frame's outer dimensions, not just the poster size.
- If using a mat, add 2-4 inches to each side for the mat width.
Step 5: Visualize and Plan the Layout
Before you finalize your order, visualize how the poster will look on the wall. You can use painter's tape to mark the outline of the framed poster on the wall. Step back and see if it feels right. Adjust the size or position as needed. This simple trick helps avoid disappointment after the poster arrives.
Also, consider the surrounding decor. If you have other frames or art, think about how they will work together. A single large poster can be a focal point, while a group of smaller posters can create a gallery wall. For a cohesive look, keep a consistent gap between frames and align the tops or centers.
- Use a level to ensure your tape outline is straight.
- Take a photo of the wall with the tape outline to see it from a different perspective.
Your Measuring Checklist
- Pick the wall: Choose the wall and note any furniture or obstacles. Determine the ideal viewing distance and the proportion of the wall you want the poster to fill. Aim for the poster to cover 60-75% of the wall space.
- Measure the space: Use a tape measure to record the width and height of the open wall area. Subtract a 2-4 inch margin on all sides for breathing room. Double-check your measurements to avoid errors.
- Choose the poster size: Compare your usable dimensions to standard poster sizes. Consider the aspect ratio of your child's art to minimize cropping. Select a size that fits within your measured area.
- Account for the frame: Add the frame width to your poster dimensions to get the total footprint. If using a mat, add extra inches for the mat. Ensure the framed size fits your wall space.
- Visualize with tape: Mark the outline of the framed poster on the wall with painter's tape. Step back and adjust size or position as needed. This helps you avoid ordering a poster that's too big or too small.
