– Dynamic Pricing: Once the Threshold limit is exceeded, the Dynamic price will be considered as per the square area.

– If you have selected Custom Size as the type of product then you can’t change its type once it is saved

You can add the default height & width of the canvas for the selected product:

You can add Canvas Size templates for different types of cards, letters, and cover pages.
The customers can set the canvas (product size) to design the product if you have enabled the ‘canvas resize on the product detail page’ option from the Manage Layout.

They can also enable the ‘aspect ratio’ by clicking on the tiny ‘lock’ icon to maintain the height & width in a proper format.
When you change the unit, the inserted value will be converted based on the DPI, formula:
Pixels ÷ DPI = Inches
Pixels ÷ (DPI * 2.54) = Centimeter
Now, by clicking on the DESIGN IT button, the customers will be navigated to the product designer tool page where they can see the Canvas Resize on the header.
The canvas resize will appear as per the inserted details from the product detail page for Canvas. You can customize the height and width, size unit, and aspect ratio manually for product design. 
How will Flat & Dynamic prices be calculated?
– The Product price will be calculated as per the Flat Pricing, Dynamic Pricing & Canvas Threshold values inserted in the backend in the product details page.
– If the canvas area value is less than the Threshold, the Product Price will calculate: Flat Price X Qty.
– If the canvas area value is greater than or equal to the Threshold, the Product Price will calculate:
(l X b X Dynamic Price) X Qty
– Suppose from the backend the following Value are inserted:
Flat Pricing: 15 | Dynamic Pricing: 35 | Canvas Threshold Value: 0.05 (meter)
Now, if you inserted Width: 0.10 & Height: 0.15, Flat Rate would calculate.
Area: 0.10*0.15 = 0.015 which is less than the Threshold Value 0.05 m.
So the Flat Rate will calculate Product Price (100€) + Flat Rate(15€) = 115€
Now, if you inserted Width: 0.42 & Height: 0.42, the Dynamic Rate would calculate.
Area: 0.42*0.42 = 0.1764 is greater than or equal to the Threshold 0.05 m.
So the Dynamic Rate will calculate: 100€ + (0.1764*35€)*1 = 100€ + 6.17€ = 106.17€
– Zoom In & Zoom Out and Undo-Redo will be disabled by default for Canvas Resize.
– Form-based addons will not work on the product detail page with the custom type product.
