القياس على شريط القياس.

A natural Egyptian-style pronunciation would be roughly:

el-ʔeyās ʿala šarīṭ el-ʔeyās

A few useful notes:

• ق is often pronounced as a glottal stop ʔ in Egyptian Arabic.
• على is usually said as ʿala in Egyptian, not the more formal ʿalā.
• شريط sounds like sha-REET, with a long ee.
• The final ط is an emphatic t sound.

If you were reading it in Standard Arabic, it would be closer to:

al-qiyās ʿalā sharīṭ al-qiyās

Here is the breakdown:

• القياس = measuring / measurement
• على = on / upon / against / using, depending on context
• شريط = tape / strip
• القياس in شريط القياس = measuring

So شريط القياس literally means the tape of measuring, which is the normal Arabic way to say measuring tape or tape measure.

The two instances do not have the same job.

• The first القياس is the main noun of the phrase: measurement or measuring.
• The second القياس is part of the expression شريط القياس, which means measuring tape.

So this is not just pointless repetition. Arabic often builds phrases this way, even when the same root appears more than once.

Because شريط القياس is an iḍāfa construction, often called a construct phrase or possessive structure.

In this structure:

• the first noun is شريط
• the second noun is القياس

Literally, it is tape of measuring.

Important rule:

• the first noun in an iḍāfa normally does not take الـ
• the whole phrase can still be definite because the second noun is definite

So:

• شريط قياس = a measuring tape
• شريط القياس = the measuring tape

Because Arabic often prefers a noun-plus-noun structure where English uses a noun plus modifier.

English:

• measuring tape

Arabic:

• شريط القياس
• literally tape of measuring

That is very common in Arabic. Another way to think about it is that Arabic often links nouns together instead of using an adjective where English might.

The basic meaning of على is on or upon, but in real usage it can also mean things like:

• on
• against
• using
• by means of
• according to what is shown on

In a phrase about measurement, على شريط القياس can suggest the idea of something being measured on or using a measuring tape.

So even though على is often introduced as on, its actual meaning depends a lot on context.

It is understandable, but it sounds more formal or like a label, caption, or manual phrase than casual everyday speech.

Why?

• القياس is a fairly formal noun
• شريط القياس is correct, but everyday Egyptian may use simpler phrasing depending on the situation

In casual Egyptian, people might sometimes use:

• المتر for a tape measure in some contexts
• a more verbal expression instead of a noun phrase

So this phrase feels more like written Arabic or instructional language than spontaneous conversation.

It feels more like a heading, caption, or topic label than a complete everyday sentence.

Arabic often uses short noun phrases without a verb in titles and labels. So القياس على شريط القياس could work as something like:

• a section title
• an instruction heading
• a caption under an image

In normal conversation, you would often expect a fuller structure, depending on what you want to say.

This is a very common learner question.

• قياس usually refers to measuring or measurement as a process or concept
• مقاس usually refers to a size or the resulting measurement

Examples:

• قياس الطول = measuring length
• مقاسي كبير = my size is large
• مقاس الحذاء = shoe size

So in this phrase, قياس makes sense because the idea is about measurement/measuring, not clothing size or a finished size result.

The first القياس is a noun, specifically a verbal noun, often called a maṣdar.

That means it expresses the idea of the action itself:

• to measure is the verb idea
• قياس is the noun idea: measuring or measurement

Arabic uses verbal nouns a lot, especially in headings, instructions, formal writing, and abstract statements. English sometimes does something similar with words like:

• measurement
• reading
• writing
• movement

So starting the phrase with القياس is grammatically normal.
