Custom Invitation Envelopes

Deliver Elegance Before the Invitation Is Opened

Your envelope is more than just packaging—it’s part of the invitation itself. With custom sizes, finishes, and printing options, we help you create envelopes that feel as special as the occasion they represent.

Materials

We use fine-quality, customizable paper stocks to give your envelope both beauty and durability:

• Textured Paper – Adds tactile elegance with linen, felt, or laid textures
• Smooth Matte or Gloss Paper – Sleek finish for modern, minimal designs
• Pearlescent or Metallic Stock – Subtle shimmer for weddings or luxury events
• Kraft Paper – Rustic and eco-conscious for artisanal or vintage-style invites

All paper options are thick enough to protect the invitation inside, and available in a range of colors and finishes.

Sizes

We create invitation envelopes in any size or shape to fit your specific card dimensions:

• Standard A-sizes – A7, A6, A2, etc., perfect for formal invitations
• Square envelopes – Great for modern or creative invitation styles
• Custom die-cut shapes – For unique formats or oversized inserts

No matter your event or brand, we ensure your envelope fits precisely and delivers beautifully.

• CMYK or Pantone color printing for full-color accuracy
• Letterpress or foil stamping for a tactile, elegant finish

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.
