Maximum Length of Title and Meta Description???

With recent update, Title tag can limits to 512 pixels and Meta Description upto 300 to 320 characters

now i think but long , 155-160 ký tự.

Max length of Title Tag is 60-65 Characters and Description is 150-156 Characters.

The TITLE tag limit is 55-60 characters;
The META Description tag is 155-160 characters.

Meta descriptions may be any length, however search engines like google usually truncate snippets longer than 160 characters. it is excellent to keep meta descriptions lengthy enough that they're sufficiently descriptive, however shorter than that 160-character limit.

Title should be in between 50-60, meta description 150-160

Meta descriptions with Space 160 characters and Title: 60-70 max.

i like this answer with Space maximum Length of Title: 60-70 and Meta Description: 160 - 170
