View the video for a comprehensive overview on how size boundaries work in both the advanced letter and frame fit models.
What are size boundaries
Size boundaries are pricing tiers that help you set different prices based on the dimensions of your signs. Think of them as pricing brackets - smaller signs use one price structure, medium signs use another, and larger signs use yet another. This allows you to accurately price your signs based on the actual materials and labour required for different size ranges.
For example, you might charge higher rates per centimetre for smaller signs (which require more detailed work) and lower rates for larger signs (which benefit from economies of scale).
How to Access Size Boundaries
Navigate to your Sign Customiser admin panel
Select the customiser you want to configure
Click on 'Pricing' in the left-hand menu
Choose either 'Add Pricing' for new pricing or click on an existing pricing scheme to edit
Scroll down to the 'Size Boundaries' section
Click 'Add size boundary' to create your first tier
Setting Up Your First Size Boundary
For Advanced Letter Pricing:
Click the 'Edit' button on Size Boundary 1
Enter the Maximum Width (in cm) - signs up to this width will use this pricing tier
Enter the Maximum Height (in cm) - signs up to this height will use this pricing tier
If using volumetric shipping, you'll also see Maximum Length or Fixed Sign Length fields
Set your pricing inputs (Material Cost per cm, Start Price, and Shipping Price)
Click 'Done' to save
For Frame Fit Pricing:
Click the 'Edit' button on Size Boundary 1
Enter the Maximum Width (in cm) for frames that will use this pricing
Enter the Maximum Height (in cm) for frames that will use this pricing
Set your Sign Start Price and Shipping unit price (per cm²)
Click 'Done' to save
Adding Multiple Size Boundaries
Click 'Add size boundary' below your existing boundaries
The new boundary will copy settings from your previous tier
Edit the new boundary:
Increase the Maximum Width and Height values (they must be larger than the previous tier)
Adjust the pricing values for this larger size range
Typically, you'll want lower per-unit costs for larger signs
Click 'Done' to save
Understanding How Size Boundaries Work
First Matching Tier: The system checks sign dimensions against your boundaries in order and uses the first tier where the sign fits
Infinity Rule: Your last size boundary continues to infinity - any sign larger than your highest boundary will use that tier's pricing
Both Dimensions Matter: A sign must fit within both width AND height limits to use that tier
Progressive Sizing: Each tier must have larger dimensions than the previous one
Important Notes
You must always have at least one size boundary
Width and height values must be positive numbers
Each new boundary must have dimensions larger than the previous one
Changes to size boundaries affect pricing immediately for new customer orders
The system will display an error if you try to save invalid boundary values
Tips for success
Start Simple: Begin with 2-3 size boundaries and add more as needed
Consider Your Costs: Set boundaries based on where your material or labour costs change significantly
Test Your Pricing: Use the preview function to see how different sign sizes will be priced
Regular Reviews: Revisit your boundaries periodically as your business grows
Illustrative examples of how size boundaries work
In these examples,
There are three size boundaries associated with one pricing formula.
Each size boundary is represented as a grey square
The customer's sign dimensions are the red rectangle
Example 1
Since the sign dimensions width is greater than both size ranges 1 and 2, the shipping cost, material cost and optional base price values of size range 3 will be used.
Example 2
In this example, the height is greater than size range 1. The shipping cost, material cost and optional base price values of size range 2 will be used.
