Quotas and limits

This document lists the quotas and limits that apply to Translation Hub.

A quota limit restricts how much of a shared Google Cloud resource your Google Cloud project can use, including hardware, software, and network components. Therefore, quota limits are a part of a system that does the following:

  • Monitors your use or consumption of Google Cloud products and services.
  • Restricts your consumption of those resources for reasons, which include ensuring fairness and reducing spikes in usage.
  • Maintains configurations that automatically enforce prescribed restrictions.
  • Provides a means to request or make changes to the quota.

In most cases, when a quota limit is exceeded, the system immediately blocks access to the relevant Google resource, and the task that you're trying to perform fails. In most cases, quota limits apply to each Google Cloud project and are shared across all applications and IP addresses that use that Google Cloud project.

To increase or decrease most quota limits, use the Google Cloud console. For more information, see Request a higher quota limit.

There are also limits on Translation Hub resources. These limits are unrelated to the quota system. Limits cannot be changed unless otherwise stated.


The following quotas apply to a project. You can request a quota change through the Cloud Translation - Advanced API quotas page.

The number of Translation Hub portals 1,000
The number of concurrent translation jobs Unlimited
The number of pages that can be translated per minute Unlimited
