    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.

    Delivering Premium Packaging. Materials Tailored for Your Brand and Product.

    Foil Stamping

    Add a premium metallic finish to your packaging with foil stamping. It enhances brand visibility and gives boxes a luxury appearance.

    Spot UV

    Spot UV adds glossy highlights to selected areas of your packaging design. It creates contrast and improves the overall visual appeal.

    Gloss

    Gloss finishing provides a smooth and shiny surface that makes packaging colors look more vibrant and professional.

    Holographic Foiling

    Holographic foiling creates a reflective rainbow effect that changes under light. It gives packaging a modern and eye catching look.

    Embossing

    Embossing raises selected design elements above the surface of the packaging. It adds texture and creates a premium feel.

    Debossing

    Debossing presses graphics into the packaging surface for a clean and elegant appearance. It adds depth and sophistication.

    Matte

    Matte finishing gives packaging a smooth non shiny surface. It reduces fingerprints and provides a modern premium look.

    Soft Touch Lamination

    Soft touch lamination adds a velvety smooth texture to your packaging. It also protects printed surfaces from scratches and wear.
