When measuring a custom box, there are a few technical specifications that must be considered to ensure proper design, manufacturing, and fit for the product. Here are the major technical things to measure a custom box:
Inside Dimensions (Critical for Product Fit)
- Length (L): The longest side of the box measured inside from one corner to the opposite corner.
- Width (W): The shorter side of the box measured inside perpendicular to the length.
- Depth/Height (D or H): Measured inside from the bottom to the top opening of the box. Always specify that dimensions are given in Length × Width × Height.
Outside Dimensions (Important for Shipping & Storage)
- Measure the outer surfaces of the box including material thickness.
- Outside measurements are used for pallet stacking, warehouse spacing, and shipping compliance.
Material Thickness (Board Caliper)
- The thickness of the packaging material (e.g., corrugated board, rigid stock, cardstock).
- Impacts both the internal usable space and external dimensions.
Flap Measurements
- For boxes with flaps (e.g., mailer or shipping boxes), measure:
- Inner flaps: Ensure they meet in the middle without overlapping too much.
- Outer flaps: Allow proper sealing without gaps.
Tolerances
- Account for manufacturing tolerances (usually ±1/16" or ±2mm depending on material).
- Ensure the product fits without being too tight or loose.
Volume Capacity
- Calculate internal cubic capacity (L × W × H).
- Helps in determining how much space the product will occupy and shipping efficiency.
Product Orientation
- Decide how the product sits inside the box and measure accordingly.
- Orientation affects whether length or width is the primary dimension.
Die-Cut Openings or Windows
- Measure exact placement, height, and width for any cutouts.
- Ensure structural integrity when adding windows.
Printing Bleed & Safe Zones
- Include measurements for:
- Bleed area: Extra space beyond the cut line for printing.
- Safe zone: Inner area where critical text or logos should be placed.
Closure Type & Locking Tabs
- Measure slots, tabs, or locks for boxes with custom closures.
- Precision is required to avoid misalignment during assembly.
Packaging Style
- Folds, creases, and scores must be measured for accurate dieline creation.
- Different styles (e.g., RSC, tuck-end, mailer, sleeve) require specific panel measurements.
