有大一点的吗?
Is there a larger size?
有 (yǒu) means 'have', 大 (dà) means 'big', 一点 (yìdiǎn) means 'a bit', 的 (de) is a particle that makes it a noun phrase, and 吗 (ma) makes it a question. Literally 'Have a bit bigger one?'
有没有大一点的
yǒu méiyǒu dà yìdiǎn de
Is there a bigger one? — More polite due to the alternative question form with 有没有.
可以大一点吗
kěyǐ dà yìdiǎn ma
Can it be a bit bigger? — More casual and direct.
请问,有大一点的吗?
qǐngwèn, yǒu dà yìdiǎn de ma?
Excuse me, is there a larger size?
有的,请稍等。
yǒu de, qǐng shāo děng.

Appropriate
Avoid when
You can say '有大一点的吗?' (yǒu dà yìdiǎn de ma?), which literally means 'Is there a bit bigger one?'
It is pronounced 'yǒu dà yìdiǎn de ma?'. Pay attention to the tone changes: yǒu (3rd tone), dà (4th tone), yì (4th tone due to tone sandhi before diǎn), diǎn (3rd tone), de (neutral), ma (neutral).
Both are polite, but '有大一点的吗?' is slightly more formal and common in standard Mandarin. '有没有大一点的' is also polite but more colloquial and often used in southern China.
