你们公司在当地算大公司吗？请帮忙检查英语翻译

in comparsion to 是“比作”要改成 in comparsion with
big应改成large
Is your company considered large company in conparsion with others in your local area?
或者 Does your company belongs to the large company in your local area?

Is your company considered as a bigger company in comparation to other local companies？

还要加上as，去掉the（因为没有特别指定），comparation应该这样写。

建议你换种说法:
Is your company a big company in your city(town, country...)?

你的中式翻译中有错误 big 改为 a bigger company
