Ti-Hi Pallet Counting

How to Automate Ti-Hi Pallet Counting in the Warehouse

Ti-Hi counting, also known as Tie-High, is a critical metric in warehousing and logistics. It refers to the number of cases per layer (Ti or Tie) and the number of layers per pallet (Hi or High). This method is essential for efficient palletization, maximizing storage space, and ensuring safe transportation of goods. Here we explore the importance of Ti-Hi counting, calculating it, and how PalletSCAN 150 automates this process and provides fast and accurate counting of pallet contents.

Pallet Ti Hi Counting and Scanning

Automating Ti-Hi counting improves warehouse efficiencies and accuracy.

Ti-Hi counting pallet layers

For those not familiar with the process, Ti-Hi is a standardized way of describing how products, cases and boxes are stacked on a pallet. Here’s a breakdown:

– **Ti (Tie)**: The number of cases that fit on a single layer of the pallet.

– **Hi (High)**: The number of layers stacked vertically on the pallet.

For example, if you have a pallet with a Ti of 10 and a Hi of 5, it means each layer has 10 cases, and there are 5 layers high, making a total of 50 cases on the pallet.

Manual Ti Hi counting is slow error prone and delays pallet processing

Effective Ti-Hi counting allows warehouses to optimize space and maximize their overall storage efficiencies.  Unfortunately, this can also be a slow, error prone and labor-intensive process; but warehouses can now automate this process with warehouse computer visionPalletSCAN 150 is an automated drive through computer vision enabled gate, engineered to provide precise side scanning and Ti-Hi case counting.  Leading 3PLs and warehouses use this automated computer vision system to quickly capture the exact Ti-Hi allowing them to optimize pallet space, reducing the number of pallets needed and maximizing their overall storage efficiencies.  Additional benefits of the computer vision solution include:

  •  Ensures Stability and Safety: Proper Ti-Hi counting ensures that pallets are stable during transportation, minimizing the risk of damage to goods.
  • Streamlines Inventory Management: Accurate Ti-Hi counting helps in quick inventory audits and management, improving overall operational efficiency.

How to Calculate Ti-Hi

Physical dimensioning is required for manual Ti Hi counting and inspection

Calculating Ti-Hi involves understanding the dimensions of the product and the pallet. Here’s a step-by-step process:

1. Measure the Product: Determine the dimensions (length, width, height) of the product cases.

2. Measure the Pallet: Determine the dimensions of the pallet.

3. Calculate Ti: Divide the pallet’s length and width by the product’s length and width to determine how many cases fit per layer.

4. Calculate Hi: Divide the pallet’s height by the product’s height to determine how many layers fit vertically.

Ti Calculation:

– Pallet length (48”) / Product length (12”) = 4

– Pallet width (40”) / Product width (12”) = 3.33 (rounded down to 3)

– TI = 4 x 3 = 12

Hi Calculation

– Pallet height (60”) / Product height (10”) = 6

– HI = 6

TI-HI: Therefore, the TI-HI for this pallet is 12 x 6, meaning each pallet holds 72 cases.

1. Consistent Measurement: Ensure all measurements are consistent and standardized across the warehouse.

2. Regular Audits: Perform regular audits to verify the accuracy of TI-HI calculations and adjust as necessary.

3. Use Technology: PalletSCAN 150 automates pallet scanning and calculates Ti-Hi data in real time.  This system can also be integrated with a warehouse WMS ensuring Ti-Hi data is validated and recorded in the warehouse system of record.

4.  Train Staff: Educate warehouse staff on the importance of TI-HI counting and how to perform calculations accurately.

Pallet auditing in the warehouse

Q: Can Ti-Hi counting be applied to all types of pallets?
A: Ti-Hi counting can be applied to various types of pallets, but the dimensions of the pallets and boxes must be considered for accurate calculations.

Q: What are some common mistakes to avoid in Ti-Hi counting?
A: Common mistakes include inaccurate measurements, not considering weight distribution, and failing to adhere to safety standards.

Q: What are the benefits of automating Ti-Hi counting?
A: Mastering Ti-Hi counting is essential for any warehousing and logistics operation. Automating the process with PalletSCAN 150 maximizes storage space, minimizes required labor, and improves warehouse efficiencies but also enhances safety while reducing overall costs.

 By following the steps outlined above and utilizing the right tools, you can optimize your palletizing process and achieve greater operational success.

Ti-Hi Counting and Scanning FAQ

PalletSCAN 150 enables fast drive through automated Ti-Hi counting capabilities

Warehouses that use PalletSCAN 150 benefit from near-instant Ti-Hi assessment and validation of pallet contents and counts.  PalletSCAN 150 drive through stations are equipped with heads-up terminal display screens that present status results of each pallet and alerts users if a pallet fails validation. Along with station-side reporting, warehouses also benefit from the Vimaan web application, ViewDECK that provides actionable insights, reporting and digital photos of all pallet sides. 


Ti-Hi counting is a fundamental aspect of effective warehouse management. By understanding and implementing accurate Ti-Hi calculations, warehouses can improve storage efficiency, ensure the safe transportation of goods, and streamline inventory management. For businesses looking to enhance their warehousing operations, automating Ti-Hi counting is a crucial step towards achieving operational excellence.

PalletSCAN 150 compares the collected data against the Advanced Shipping Notice (ASN) to ensure accuracy and consistency. For pallets that pass the inspection, the system automatically receives the goods into the Warehouse Management System (WMS). If any discrepancies or exceptions are detected, such as incorrect case count, damages, or other visible anomalies, PalletSCAN 150 triggers a warning to alert operators. The camera images captured during the scanning process are archived in a searchable dashboard for easy access and reference. This feature is particularly useful for handling claims and investigating any issues related to specific pallets or shipments.
