Sterling Ink products all have different grid sizes. They have a general sizing guide on their website but I spoke to someone at Sterling Ink and they said the best, most accurate way to get the grid size is to refer to the exact product page of the planner you have. All the grid sizes are listed there! Once you have that grid size, you can return here to find the kits to match your specific planner.

For grid sizes that are uniformly square (e.g., 4mm x 4mm), simply purchase the kits that match the measurement... in the 4mm x 4mm example, purchase the 4mm kits.

For grid sizes that are not uniformly square (e.g., 3.7mm x 3.9mm), here is the guide to follow:

• For tracking strips that go left to right across the page, use the kits that follow the first number (in the 3.7mm x 3.9mm example, you would purchase the 3.7mm kits).
• For tracking strips that go top to bottom on the page, use the kits that follow the second number (in the 3.7mm x 3.9mm example, you would purchase the 3.9mm kits).

See product photos for more examples!

Please note: 3.6mm kits are coming soon!
